The guidance is intended to be of a general nature and is divided into two distinct sections covering those vessels that are “in class” with a recognised organisation and those that are not “in class”. Specific problems relating to individual vessels may require reference to more detailed guidance information. The guidelines should be regarded as a live document and further or more detailed guidance may be included going forward. Although primarily aimed at existing vessels, the guidelines may also have relevance with respect to specific issues for new vessels. 2 Definitions “length overall (Loa)” means the length measured on a straight line from the fore part of the stem at top to the aftermost side of the transom or stern contour; “length (L)” means 96 per cent of the total length on a waterline at 85 per cent of the least depth, or the length from the foreside of the stem to the axis of the rudderstock on that waterline, if that length is greater. In vessels designed with rake of keel the waterline on which this length is measured shall be parallel to the designed waterline; “new fishing vessel” means: in relation to a vessel of 24 metres in length (L) and over, a fishing vessel for which (a) on or after 1 January 1999 the building or major conversion contract is placed; or (b) the building or major conversion contract has been placed before 1 January 1999, and which is delivered three years or more after that date; or (c) in the absence of a building contract, on or after 1 January 1999: - the keel is laid, or - construction identifiable with a specific ship begins, or - assembly has commenced comprising at least 50 tonnes or 1 % of the estimated mass of all structural material, whichever is less; in relation to a vessel of 15 metres in length overall and over but less than 24 metres in length (L), a fishing vessel the keel of which is laid or which is at a similar stage of construction on or after 1 October 2007 “existing vessel” means a fishing vessel, which is not a new vessel 3 Legislative references The sea fisheries licensing authority may not issue a licence until a vessel complies with the safety requirements and the owner submits a copy of an appropriate safety certificate confirming this. S.I. 418 of 2002. Fishing Vessel (Safety Provisions) Regulations, 2002 3 Rev 0 - 06/04/09 These regulations implement Council Directive 97/70/EC as amended. The directive, in turn, implements and amends the Torremolinos Convention 1977 as modified by the 1993 Protocol in order to introduce a harmonised safety regime for fishing vessels of 24 metres in length and over. The Torremolinos Protocol as amended by Council Directive 97/70/EC (as amended) applies principally to new fishing vessels of 24m length and over, with some limited parts applying to existing vessels. For the purpose of these guidelines the relevant part of the directive is Article 5, which states that: - “the standards for the design, construction, and maintenance of hull, main and auxiliary machinery, electrical and automatic plants of a fishing vessel shall be the rules in force at the date of its construction, specified for classification by a recognised organisation, or used by an administration.” In addition to the requirements of this S.I. existing fishing vessels of 24 metres in length and over must still comply with, inter alia, the requirements of the Life-Saving and Fire-Fighting requirements of the “1967 Rules”. S.I. No. 640 of 2007. Merchant Shipping (Safety Of Fishing Vessels) (15-24 Metres) Regulations 2007 These regulations apply to every mechanically propelled fishing vessel of 15 metres in length overall and over but less than 24 metres in length, registered in the State. The regulations set out the standards for the safe construction and equipment of fishing vessels and also the survey and certification requirements for new and existing vessels. The regulations will apply initially to new vessels and then to existing vessels on a phased basis: (a) on 1 October 2007, for new vessels, (b) on 1 October 2008, for existing vessels the keel of which was laid or which was at a similar stage of construction on or after 1 October 1997, (c) on 1 October 2009, for existing vessels the keel of which was laid or which was at a similar stage of construction on or after 1 October 1987, and (d) on 1 October 2010, for existing vessels the keel of which was laid or which was at a similar stage of construction before 1 October 1987. S.I. No. 325 of 1999. Safety, Health and Welfare at Work (fishing vessels) Regulations 1999. These regulations are made under the Safety Health and Welfare at Work Act 1989 and apply to new vessels of 15m length and over and existing vessels of 18m length and over. (Although the Act has been subsequently replaced, the Regulations remain in force.) For these regulations a new vessel is one whose keel was laid on or after 23 November 1995. Although the majority of the requirements of this S.I. have been incorporated in S.I. No.640 of 2007, the S.I. in its entirety still applies to vessels of 24m length and over. For all vessels certain provisions covering hoisting equipment and hauling gear, etc are the responsibility of the Health and Safety Authority. 4 Rev 0 - 06/04/09 Prior to conducting surveys it will be necessary to have a copy of this S.I. and an understanding of which parts are relevant. Other Legislation In addition to the above fishing vessel safety regulations, there are a number of other Statutory Instruments, including those related to Marine Pollution, Collision Regulations & Manning, which apply to fishing vessels and their crews. Surveyors, Owners and Skippers should be familiar with these and a list of applicable legislation is available from Marine Surveyors‟ Offices. 4 Surveys of Fishing Vessels – General Information 4.1 Scope of survey The matters on which the surveyor is to be satisfied are indicated in Regulation 71 and Regulation I/61. In respect of radio equipment and installations the surveyor should ensure that a radio surveyor has issued a declaration of survey. The surveyor should check, as far as possible, that the details supplied on the SUR6 application form are correct and refer to the vessel being presented for survey. 4.2 Survey of classed vessels Where the survey of a vessel classed with a recognised organisation for the issue of a Fishing Vessel Safety Certificate or a Fishing Vessel Certificate of Compliance is to be undertaken, a valid hull and/or machinery class certificate issued by the recognised organisation may be accepted by the Minister as an equivalent provision for those items covered by Parts 2 & 4 or Chapter II & IV as appropriate, provided there is no evidence of non-compliance. The guidance in Part C should be followed. Where there is a clearly identified shortfall in any classification society rules in respect of compliance with a specific requirement of the applicable statutory regulations, then this should be brought to the attention of the Chief Surveyor. 4.3 Survey of un-classed vessels The surveyor should follow the guidelines in Part B when the vessel is opened out for survey. These guidelines are not to be taken as the maximum requirements in respect of the survey of fishing vessels and where he/she considers that additional examination, opening out or testing is necessary in order to be satisfied, the surveyor should ensure that his/her requirements are complied with. 4.4 Construction Standards for Existing Vessels For existing vessels, a satisfactory service history may be taken as satisfactory evidence that the strength and construction is sufficient to withstand all foreseeable conditions of intended service. Where any doubt exists in relation to strength issues a more in depth analysis may be 1 Regulation References in italics refer to the Torremolinos Protocol & those in “normal” refer to SI 640 of 2007. 5 Rev 0 - 06/04/09 undertaken. The vessel will be inspected in relation to structural corrosion and damage in the normal manner. 4.5 Preparation for Survey Surveyors should be familiar with the MSO Surveyor Activities section of the Safety Statement for the Department of Transport. In addition surveyors should make themselves familiar with the safety statements and procedures of shipyards, boatyards, repair facilities, etc. Particular attention should be paid to tank entry, means of access and working aloft. Owners and skippers should be advised that they must have their vessel prepared for survey and their attention brought to the leaflet „IT PAYS TO BE PREPARED FOR YOUR VESSEL SURVEY‟ which is reproduced at Appendix 2. All available drawings for the vessel are to be submitted prior to the initial visit. Where no construction drawings are available a scantling analysis is to be submitted demonstrating that the construction and strength of the vessel is adequate for the intended operational areas. The surveyor may accept scantlings for a vessel that was constructed in accordance with “BIM” or “Sea Fish” (UK) prescribed schemes. Other standards may be considered and details should be forwarded to the Chief Surveyor. The Owner is to provide the necessary facilities for a safe execution of the survey. Means are to be provided to enable the Surveyor to examine the structure in a safe and practical way. Tanks and spaces are to be safe for access, i.e., gas freed, ventilated, illuminated, etc. In preparation for survey and thickness measurements and to allow for a thorough examination, all spaces are to be cleaned including removal from surfaces of all loose accumulated corrosion scale. Spaces are to be sufficiently clean and free from water, scale, dirt, oil residues etc. to reveal corrosion, deformation, fractures, damages or other structural deterioration. However, those areas of structure whose renewal has already been decided by the owner need only be cleaned and de-scaled to the extent necessary to determine the limits of the renewed areas. Sufficient illumination is to be provided to reveal significant corrosion, deformation, fractures, damages or other structural deterioration. 4.6 Equipment for Survey Thickness measurement is normally to be carried out by means of ultrasonic test equipment. The accuracy of the equipment is to be proven to the Surveyor, as required. One or more of the following fracture detection procedures may be required if deemed necessary by the Surveyor: • Radiographic examination. 6 Rev 0 - 06/04/09 • Ultrasonic examination. • Magnetic particle examination. • Dye penetrant examination. Companies or individuals approved by Recognised Organisations may be used to carry out thickness measurement or non-destructive testing. Other persons who possess the required training in NDT techniques and who operate in accordance with a satisfactory quality control procedure may also be acceptable to the Minister. The surveyor should not accept NDT that has been carried out by the owner or his representative. 7 Rev 0 - 06/04/09 PART B SURVEYS OF VESSELS NOT IN CLASS WITH A RECOGNISED ORGANISATION 1 Initial & Periodical surveys - General The survey of existing fishing vessels should include: (a) a complete and thorough examination of the vessel's structure both internally and externally; (b) an examination of all fittings and appliances for the protection of openings, including: (i) Hatchways, manholes and scuttles in freeboard and superstructure decks, (ii) Machinery casings and covers, funnel annular spaces, skylights, companionways and deckhouses protecting openings in freeboard or enclosed superstructure decks, (iii) Portlights together with deadlights, cargo ports, chutes and similar openings in vessel‟s sides or ends below the freeboard deck or in way of enclosed superstructures, (iv) Ventilators, air pipes together with flame screens, scuppers and discharges serving spaces on or below the freeboard deck. Air pipe “closure devices” are to be randomly opened out and their condition verified, (v) Watertight bulkheads, bulkhead penetrations, end bulkheads of enclosed superstructures and the operation of any doors in same, (vi) Weathertight doors and closing appliances for all of the above including stiffening, dogs, hinges and gaskets. Proper operation of weathertight doors and closing appliances to be confirmed; (c) Sea chests, sea suction and overboard discharge valves; (d) Freeing ports, together with bars, shutters and hinges; (e) Guard rails, lifelines, gangways and deck houses accommodating crew; (f) An examination of the stability and, where applicable, loading and ballasting in- formation which is required to be supplied to the skipper. Such tests, as the surveyor considers necessary, should be carried out to ascertain the foregoing. Where in an exceptional case the Minister allows departures from the requirements of the Regulations the arrangements shall provide an equivalent standard of safety and protection and be no less effective than those provided for in the Regulations. 1.1 Survey of steel or aluminium vessels The vessel should be placed in a dry dock or on a slipway on blocks of sufficient height to 8 Rev 0 - 06/04/09 enable the bottom shell plating to be examined thoroughly fore and aft to ensure that its condition is satisfactory. When in dry dock or on a slipway the remaining shell plating and its means of connection, i.e. riveting or welding should also be examined; the surveyor should be afforded safe access to any area of shell plating which he/she considers it necessary to examine. Internally the examination should include the plating, framing and means of connection etc in the double bottom, holds, 'tween decks, peaks, accommodation and machinery spaces; and any ceiling sparring, linings and insulation should be removed wherever the surveyor considers it to be necessary. The plating and beams of the working and superstructure decks should be surveyed and the surveyor may require portions of deck planking, deck composition or tiling to be removed where deterioration is evident or suspected. At each renewal survey all tanks, which are an integral part of the hull structure, are, in general, to be surveyed internally. Where such tanks are used exclusively for the carriage of oil fuel they need not be examined at each renewal survey unless as a result of an external survey or for any other reason the surveyor considers it necessary. Independent oil tanks in machinery spaces are to be externally examined and, if deemed necessary, tested under a head of liquid. Cross-levelling arrangements fitted for stability purposes should be examined. Boundaries of double-bottom, deep, ballast, peak and other tanks are to be tested with a head of liquid to the top of air pipes, except that fuel oil and lube oil tanks may be tested to the highest point that liquid will rise under service condition. Tank testing of fuel oil, lube oil and fresh water tanks may be specially considered based on a satisfactory external examination of the tank boundaries. The testing of double bottoms and other spaces not designed for the carriage of liquid may be omitted, provided a satisfactory internal examination together with an examination of the tank top is carried out. The Surveyor may require further tank testing, as deemed necessary. Thickness measurements are to be carried out in accordance with the following: (i) Age ≤ 10 Years Suspect areas throughout the vessel. (ii) 10 < Age ≤ 15 Years Suspect areas throughout the vessel. Two (2) transverse sections within the amidships 0.5L. Internals in forepeak tank. (iii) Age >15 Years Suspect areas throughout the vessel. Two (2) transverse sections within the amidships 0.5L. Internals in forepeak and after peak tanks. All hatch covers and coamings (stiffeners and plating). 9 Rev 0 - 06/04/09 Bulkheads forming the boundaries of the main compartments, throughout their vertical and transverse extent taking into account any recesses or steps, which may be fitted. Wind-and-water strakes, port and starboard, full length. All exposed main deck and superstructure deck plating. Flat keel plating full length. Also, additional bottom plates in way of cofferdams, machinery spaces and aft end of tanks. For tank vessels, gauging of principal internals throughout cargo and ballast tanks. Plating of seachests. Shell plating in way of overboard discharges as considered necessary by the attending Surveyor. A detailed report of the state of the vessel including the thicknesses of plating is to be prepared. Guidance on thickness measurement and wastage allowances is given in Appendix 1 1.2 Survey of wood vessels This section is currently under development and will be inserted when complete. The MSO resources deployed in respect of an initial survey of the hull of a wooden vessel will be specially considered. Owners should be encouraged to engage a shipwright to attend at the initial survey. 1.3 Vessels constructed of other materials This section is under development and will be inserted when complete. 2 Survey of accommodation, protection of the crew, ventilation etc. The surveyor should examine the escape routes, escape hatches, and their means of operation, stairways and ladders, bulwarks and guardrails, working spaces and all items concerning the protection of the crew. All accommodation arrangements should be maintained in accordance with the requirements that could have been expected at time of build. Sanitary facilities should all be in operational condition and arranged so as not to be harmful to health. Ventilation should be adequate, heating and as appropriate air conditioning being provided. Ventilation ducts (particularly extractions from galleys) should be examined and verified not to present a fire hazard. Gas cooking arrangements should comply with requirements of Marine Notice No.1 of 2002. In particular it should be noted that domestic appliances, if fitted, might not comply with marine standards. Adequate lighting should be provided in crew mess and accommodation areas, sufficient to allow a person to comfortably read a standard newspaper size of print. Accommodation areas located below the working deck of a vessel should be specially considered. 10 Rev 0 - 06/04/09 A safe means of access to the vessel is to be provided for the crew and for all other persons having legitimate business onboard. The owners should be able to demonstrate a system or combination of systems to facilitate safe access at the normal states of the tide. Whereas it may be acceptable for persons to “step” onboard when the side of the vessel is close in and no gap exists between the boarding deck and the quay, the practice of jumping across gaps between a quay and the vessel will not be considered as a safe means of access. 3 Stability Fishing vessels of 15 metres in length and over shall possess sufficient stability for their intended service and comply with the requirements of Part 3 and Schedule 3 of the Regulations or Part III of the Protocol. It is likely that for many existing vessels additional equipment will have been added to the vessel that may have adversely affected the stability of the vessel. It may be difficult to establish if the stability information available actually relates to the vessel in its current condition. Manufacturers data plates on heavy items of deck equipment may show a date after the date on the stability information. G.A drawings as built may show different arrangements than the current ones. It will be beneficial if the owner can submit stability information and drawings prior to commencement of survey. Such checks are likely to be necessary in a substantial number of cases and should be performed prior to dry-docking or slipping in order to establish if remedial work will be necessary. Changes in fishing methods and operational practices may have resulted in conditions that give rise to inadequate stability margins. It should be verified that the skipper of the vessel is aware of any operational limitations, and is complying with any such limitations. Where doubt exists, surveyors may ask skippers to explain the stability book more fully so as to verify their understanding of the various operating conditions. The stability requirements to be complied with are set out below. (a) New Vessels. The stability information for new vessels shall comply with Part 3 and Schedule 3 of the Regulations or Chapter III of the Protocol, in full. (b) Existing Vessels. All existing vessels shall be subject to a Lightship check before the first issue of a Fishing Vessel Safety Certificate or a Fishing Vessel Certificate of Compliance. However, where an existing vessel has been subject to an inclining test, within the last 10 years, which was witnessed by a surveyor from the MSO it may not be necessary to carry out a lightship check at this time, provided the surveyor is satisfied that no modifications, which may have adversely affected the stability of the vessel, have been made – the vessel should, however, be subject to a lightship check within 10 years from the date of that inclining test. 11 Rev 0 - 06/04/09 Some existing fishing vessels may already have been subjected to an inclining test and the stability information prepared but this information may not have been submitted to the Department, as there was no requirement to do so under previous legislation. (a) Where the lightship displacement and LCG, obtained from the lightship check, are within the limits given in Regulation 38(3)(b) or Regulation III/9(2) and the information in the stability book is substantially in accordance with the requirements of Part 3 and Schedule 3 or Chapter III, the stability book can be approved. If, however, the information in the stability book is not substantially in accordance with the requirements of Part 3 and Schedule 3 or Chapter III, the stability book is to be revised and submitted for approval (b) Where the lightship displacement and/or the LCG, obtained from the lightship check, are outside the limits given in Regulation 38(3)(b) or Regulation III/9(2), the vessel is to be re-inclined and a new stability book, prepared in accordance with the requirements of Part 3 and Schedule 3 or Chapter III, submitted for approval. Where no stability book exists it will be necessary to incline the vessel, in the presence of an MSO surveyor, and submit for approval stability information based on Part 3 and the requirements of Schedule 3 or Chapter III. Special consideration may be given to the stability information provided for vessels engaged in voyages of limited extent and where particular conditions of service apply, subject to the approval of the Chief Surveyor. 3.1 Date by which stability information must be provided for fishing vessels Recognising that it may not always be possible to have the Stability Information Book approved before the Safety Certificate is issued, a Short Term Certificate may be issued for a period not exceeding 12 months provided the surveyor is satisfied that reliable provisional Stability Data is available for the use of the skipper. Owners should however be encouraged to submit stability information as soon as possible to the Department for examination and approval, particularly for vessels where no previous submissions have been made. 3.2 Inclining test The Inclining Test is to be carried out in accordance with the „Detailed guidance for the conduct of an inclining test‟ given in Annex 1 of the IMO Code on Intact Stability. 3.3 Deck cargo Fish cargo when approved for carriage on deck shall be stowed in pounds or other suitable containment so as not to interfere with or impair the following: (a) the crew working on deck, the access to their living quarters or other working spaces; (b) the free drainage of water coming on deck and (c) the effective operation of the deck closing appliances, control valves or any other operation necessary for the safety of the vessel. 12 Rev 0 - 06/04/09 3.4 Fish-hold divisions The scantlings of portable fish-hold divisions, if fitted, shall be to the satisfaction of the Minister. An acceptable standard would be that given in the attached Appendix 3 - „Recommended practice on portable fish-hold divisions‟ as set out in annex IV of the IMO Voluntary Guidelines for the Design, Construction and Equipment of Small Fishing Vessels, 2005. 3.5 Minimum Freeboard For 15 – 24m vessels, SI 640 of 2007 Reg. 41(2) requires that: - “Notwithstanding the requirements of paragraph (1), all existing fishing vessels shall have a freeboard of at least 300mm at any point along the working deck.” For vessels that do not meet the minimum freeboard criteria but do not submerge the lower deck, the following arrangements apply: - 1. Vessel built after 1st October 1997 and surveyed/inspected during construction or on completion by the MSO. 2. The working deck (lower deck) may not be submerged in any loading conditions. 3. The vessel must have a weathertight enclosure above this working deck and satisfy all other specified stability criteria. Therefore generally in line with Rule 41(3)(f). 4. The owners/consultants apply for an exemption under Rule 4(2) outlining why they require to be considered for such an exemption. For vessels that may submerge the lower deck the following may be considered to satisfy the freeboard requirement, 1. The working deck may be considered to be stepped in way of an aft weathertight bulkhead. 2. The upper deck may be considered as the working deck. In such instances the following must be considered, A. Openings such as doors in the collision bulkhead and machinery space bulkheads, which are required to extend to the working deck shall be fitted with indication to the bridge and shall have single lever operation to close. B. Penetrations in the collision bulkhead are to be examined on a case-by-case basis in relation to means of closure. Special consideration may be given to the height of any penetrations in relation to the height of any floodwater if there is damage forward of the collision bulkhead. C. Consideration is to be given to the possibility of progressive flooding of the vessel by the upwelling of floodwater from the machinery space. 13 Rev 0 - 06/04/09 D. Where an upper deck has been designated as the working deck a reduction in the coaming height of hatchways may be considered on the basis that there is an excess of freeboard to that deck. E. Where accommodation is located below a lower deck which may be submerged in service, special attention should be given to maintaining a safe means of escape from such spaces in the event of the vessel being damaged Where doubt exists concerning the designation of the working deck, full details should be forwarded to the chief surveyor. Special consideration will be given where an equivalent level of safety can be demonstrated in respect of a vessel previously constructed in accordance with the rules of a recognised organisation, which has a designated working deck that does not satisfy the rule requirements. 3.6 Treatment of Free Surfaces For 15 – 24m vessels, in relation to the method outlined in SI 640 of 2007, Schedule 3 Paragraph 11; it is an acceptable equivalent to use the methodology outlined in Chapter 3 Paragraph 3 of Res. A.749(18). 3.7 Severe Wind and Rolling For 15 – 24m vessels, SI 640 of 2007 Reg. 34 requires that: - “For vessels intended for operation in areas where exceptionally adverse weather conditions may be experienced, special attention shall be given to the capability to withstand the capsizing effects of breaking waves.” The method outlined in Chapter 3 Paragraph 2 of Res. A.749(18) as amended should be used to satisfy this requirement. Additionally the reductions in wind pressures for fishing vessels from 24m to 45m as outlined in Chapter 4 Paragraph 2 may be applied to vessels from 15m to 24m. For existing vessels with approved stability information, the owner should be requested to submit supplementary wind and rolling calculations to be retained on file. If a vessel is non-compliant with the recommended criteria, then the owner may apply to the Chief Surveyor for an operational weather restriction to be imposed, to provide an equivalent level of safety. A warning should be inserted in the stability book concerning the capsizing effect of breaking waves. 3.8 Water on Deck For 15 – 24m vessels, SI 640 of 2007 Reg. 35 requires that: - “Vessels shall be able to withstand the effect of water on deck, taking account of the seasonal weather conditions, the sea states in which the vessel will operate, the type of vessel and its mode of operation.” 14 Rev 0 - 06/04/09 The water on deck calculation is to be carried out as described in the recommendations contained in the consolidated edition of the 1993 Torremolinos Protocol. Account should be taken that a vessel to which this section applies will have to have freeing ports as required by Reg. 26 of SI 640 of 2007 and that compliance with these requirements should ensure rapid draining of trapped water on the deck The well for retention of water relates to the exposed section of deck. For vessels that have a non-weathertight bulkhead or no bulkhead within the well, the length of the well being considered is to be increased by 50% of the breadth of the vessel. However the volume of any side casings within this well may be excluded. Any non-compliance may be reviewed on a case-by-case basis in consultation with the Chief Surveyor and where a weather restriction on the vessel may be introduced to provide an equivalent level of safety. For open vessels to which this section applies a special warning is to be issued to the owner concerning the arrangement and use of pound boards on deck, which form wells. 3.9 Freeing Ports The length for the calculation of the freeing port area will be based on the length of the bulwark in way of all non-weathertight structure, subject to the restriction of 70% of the vessel length as specified in the rules. The length in way of enclosed structures/casings will not be included. No deduction or addition in area will be applied for height in relation to sections in way of shelter decks. 3.10 Use of Water Ballast For 15 – 24m vessels in relation to Rule 31(3)(a); water ballast may be permitted on the basis that it is solid in so far as it does not have a free surface effect associated with it. Therefore the ballast tank space must be fully pressed up and all pipe work that could permit the draining of the tank must be removed. 4 Survey of structural fire protection The Minister will accept the fire protection, detection and extinguishing arrangements on existing vessels providing they comply with and are maintained in accordance with previous requirements under the Merchant Shipping (Fire Appliance) Rules 1967 (S.I. No. 100 of 1967) and continue to remain efficient in service. Where structural fire protection is fitted to an existing vessel, the survey requirements are to be as follows: 4.1 Class 'A' and 'B' Divisions The surveyor should examine all 'A' Class and 'B' class divisions and satisfy himself that their integrity has not been impaired. Such an examination need not necessarily include the sighting of concealed insulation but the surveyor may at his discretion require removal of 15 Rev 0 - 06/04/09 such parts of linings etc as may be necessary to enable him to check the condition of insulation. The surveyor should also take advantage of any opportunity afforded by the removal of linings etc for other purposes to make an examination of insulation. Existing structural fire protection must have been maintained in good condition, and be free from damage, not soaked with oil vapour etc. All doors and other means for closing openings in Class 'A' and Class 'B' divisions should be inspected and their condition and efficiency checked. These inspections may be carried out when the vessel is in the upright condition but surveyors should take advantage of any opportunity afforded to check the operation of doors and shutters that are required to comply with the Regulations at any angle of the vessel's inclination up to about 3½ degrees. The surveyor should see that the means for operating dampers in ventilation and other trunkways are in proper working order and properly marked. If the surveyor finds deficiencies in the proper working order of fire doors and shutters which may be attributed to a design fault or that any of the materials used are not proving satisfactory in service he should report the matter to the Chief Surveyor so that it may be referred to the appropriate manufacturer. 4.2 Painting The surveyor should check that any repainting or resurfacing is in accordance with Regulation 80(7), and Regulation 82(8) or Protocol Ch. V. Reg. 11(3) and Reg. 31(3) where applicable. 4.3 Appropriation of spaces The surveyor should have regard to the possible existence of any storerooms and lockers or other spaces that are being used for the storage of materials, or for any purposes, other than those for which they have been designated which may affect the existing fire protection arrangements. 4.4 Alterations etc If any alterations or other work is done to a vessel the surveyor should ensure that the structural fire protection arrangements are not thereby impaired. Owners should be made aware of the importance of their giving prior notice of any proposed alterations etc which may affect the structural fire protection arrangements, together with sufficient information and such drawings as may be necessary to enable the matter to be given proper consideration and any modifications should be duly recorded in the files. When alterations are made to the fire protection arrangements it is essential that the vessel's fire control plan and the copy held by the Department are amended as necessary. Any renewals or alterations to the vessel should comply with requirements for structural fire protection in force at the time. For older vessels the presence of asbestos must be considered and dealt with by specialist contractors as appropriate. It may not be necessary to remove any asbestos provided it is adequately sealed; the recommendations of specialists in this area should be adhered to. 16 Rev 0 - 06/04/09 5 Machinery Surveys - This section is currently under development and will be inserted when complete. 6 Life-saving appliances The requirements for life-saving appliances are given in Part 7 of the regulations and in the Protocol in Ch.7 and in the Merchant Shipping (Life-Saving Appliance) Rules 1967 All appliances must be in good order and tested/serviced as required. All loose equipment (flares, line throwing equipment, boat equipment etc) should be examined and be readily available. If any exemptions have previously been granted in relation to LSA it should be verified that any conditions relating to the exemptions are being complied with. 7 Fire-fighting appliances The Minister will accept the fire protection, detection and extinguishing arrangements on existing vessels providing they comply with and are maintained in accordance with previous requirements under the Merchant Shipping (Fire Appliance) Rules 1967 (S.I. No. 100 of 1967) and continue to remain efficient in service. All appliances must be in good order and tested/serviced as required. Existing vessels may retain their manually operated emergency fire pump provided it remains effective in service. Where a portable power operated emergency pump is provided in lieu of a manual operated pump, surveyors should be satisfied that as a minimum, an equivalent level of safety has been provided. Where the fire extinguishers provided are of a type that cannot be re-charged on board, the Protocol requirement is that the number of spares to be provided should be equivalent to 50% of the required extinguishers of each type. 8 Navigational equipment. This should all comply with regulations and be in good working order. AIS where required to be fitted should comply with the performance standards developed at the IMO. Any electronic chart system used for navigation must be of an approved type. Appropriate corrected charts for the operating area are required to be carried. 9 Radio Equipment. It will be necessary for the vessel to have a radio survey. Liaison with the radio surveyors should be arranged prior to survey. 10 Conclusion of survey. With the vessel afloat machinery, LSA, fire fighting etc should all be tested. A short sea trial should be undertaken. A fire and abandon drill ship should be held. 11 Surveyor's report 11.1 General 17 Rev 0 - 06/04/09 For vessels less than 24 metres in length, the report referred to in Regulation 8 should generally consist of the following documents as appropriate: (a) Record of Particulars. (b) Report of Periodical Inspection. (c) Stability Declaration. (d) Report of Scantlings of Steel Vessels. (e) Report of Scantlings of Wood Vessels. (f) Report of Scantlings of GRP Vessels. (g) Declaration of Survey. In complicated cases when great difficulty could be experienced in compiling the particulars of the requirements of the Regulations, a drawing or plan that shows the complete information may be attached to the form. In such cases a copy of the plan or drawing should be kept on board the ship and be available for reference at all times. For over 24 metre vessels the declaration of survey should be forwarded to the Chief Surveyor together with any details of exemptions sought. 11.2 Completion of Record of Particulars In general these documents or alternative evidence will be submitted at the conclusion of the survey but where a surveyor doubts whether the vessel complies with the requirements of the Regulations he/she should make an interim report so that an early decision can be made. . Surveyors should note that where structural plans are submitted for examination and are approved by the Department he/she may in such cases refer to the plan by title, number and date of approval in the appropriate section on the report. At the initial survey the surveyor should confirm on the report that the vessel has been built in accordance with the approved plans. If at subsequent surveys alterations are found to have been made to the structure, details of the structural modifications should be included in the report or a modified structural plan submitted for approval. The surveyor should also note satisfactory completion of the survey together with any recommendation as to the period of validity of the certificate. When completing the Record of Particulars it will not be necessary to complete the diagram on Form FV2 if the surveyor forwards a suitable plan showing all the features referred to in the form. An 'as fitted' general arrangement plan would be considered suitable for this purpose. The surveyor should note that the details contained on Form FV2 (Record of Particulars) will be the determining factor in deciding whether or not a vessel complies with the Regulations. It is therefore essential that the various questions in the form are answered fully and that all particulars are provided as requested. The owners should ensure that one copy is placed on the vessel in the custody of the skipper. Where references are made on Form FV2 to the information attached thereto (e.g. approved drawings) copies of such drawings should also be kept on the vessel in the custody of the skipper. 18 Rev 0 - 06/04/09 19 Rev 0 - 06/04/09 12 Periodical survey of vessel 12.1 General Under Regulation 7 and Protocol Ch. 1, the owner is required to make application for the periodical / intermediate survey. The appropriate fee prescribed in the current fees regulations should accompany the application. Where the survey is not completed in one operation the whole survey should be commenced and completed in a period not exceeding three months. Where the survey period exceeds this time, the chief surveyor should be consulted. When such a partial survey has been carried out the surveyor should state on his/her report the items that remain to be dealt with and inform the surveyors at the port where the owners propose to have the survey completed. 12.2 Requirements for periodical surveys At each periodical / intermediate survey the surveyor must ensure that the matters referred to in Regulation 7 are in order and that the requirements of paragraphs 7(1)(b) and 7(3) or Protocol Ch I, Reg. 6(1)(b), (c) & (d) are met. During the survey the surveyor should be satisfied that where enclosed superstructures have been taken into account in the construction of the cross curves of stability the closing appliances fitted to any openings therein are fully effective and that no alterations have been made. If the surveyor finds that alterations or additions have taken place that would materially affect the stability (e.g. significant increase in the light weight of the vessel) he should ask for revised stability information to be submitted for approval. The characteristics and details of the fittings, appliances and arrangements approved for the vessel which are recorded on Form FV2 (Record of Particulars) are to be checked at each periodical survey. No hatchway or fitting in its vicinity should be inspected when work is in progress at the hatchway if this interferes with effective inspection. Advantage should be taken of any opportunity to hold the inspection when the vessel is in a dry dock, on a slipway or on a hard. The surveyor should ensure in respect of radio equipment and installations that a current certificate issued by a radio surveyor is held. 12.3 Items to be given particular attention at periodical surveys 12.3.1 Hatchways situated in the freeboard deck and hatchways within super structures which are not enclosed superstructures The surveyor should ensure that all the materials, bearing surfaces and fittings associated with hatches, including rollers, chains, hatchways coamings, beams, fore-and-afters, covers, tarpaulins, battens and securing arrangements are in good and effective condition. The whole arrangement should be assembled in place for inspection either before or after the examination of the individual parts. Steel covers and their components are to be examined carefully in place and where the surveyor has doubts as to the effectiveness of the sealing arrangements he may require tests to be carried out. Where hatch coamings are of a height less than that required under Regulation 17(1) or Ch. II. Reg. 5 & 6 or where flush hatches have been permitted the surveyor should survey these 20 Rev 0 - 06/04/09 hatches for their effectiveness and, if extensive repairs have been carried out, hose test should be carried out if necessary. The Surveyor should report any alterations that have been made to the closing appliances of enclosed superstructures. Where alterations have been made to the closing appliances reducing the effectiveness of such superstructures, the surveyor should request modification or replacement to meet the Regulation requirement. 12.3.2 Openings in the vessel‟s sides below the freeboard deck and in the sides and ends of enclosed superstructures Means of closing these openings are to be examined carefully in place and hose tested if considered necessary to ensure watertightness or weathertightness as appropriate. 12.3.3 Machinery casings, companionways and deckhouses Casings protecting machinery openings and companionways, whether separate or within deckhouses are to be examined ensuring that their sills, doors, fastenings, etc continue to be effective. 12.3.4 Freeing port shutters The surveyor should ensure that the shutters hang freely and that any fittings for retaining them in the closed position will not prevent them from opening if a substantial amount of water is shipped. 12.3.5 Ventilators and air pipes The surveyor should ensure that the closing appliances e.g. ball valves, hinged gasketed plates, flap valve steel covers etc are satisfactorily maintained and are effective. The surveyor should ensure that all fittings or appliances required by the Regulations as appropriate are in good condition. 12.4 Departures from Record of Particulars Where alterations to the Record of Particulars have been made the alterations are to be recorded on Form FV2. 12.5 Endorsement of certificates, completion of report etc On completion of the periodical survey if the surveyor is satisfied that the fishing certificate should remain in force he will (a) return the copies of forms FV2, suitably endorsed, to the skipper drawing his attention to the need to retain these documents on the vessel; (b) endorse the certificate, including the electronic copy held in the MSO and the certified copy in possession of the skipper; and (c) submit a Report of Survey and return to the ship‟s file their copies of Forms FV2 that should agree with the vessel's copies. 21 Rev 0 - 06/04/09 13 Issue of a Fishing Vessel Safety Certificate / Certificate of Compliance 13.1 Requirements relating to the issue of a certificate All new vessels shall comply with all the requirements of the Regulations relevant to their type. Existing vessels shall comply with such of the requirements of the Regulations as are applicable in their cases, due regard being paid to the issue of exemptions where full compliance would be unreasonable or impracticable bearing in mind the type of fishing on which the vessel is engaged and its foreseen life. In cases where existing vessels undergo a major structural modification, repair or alteration, the vessel should be brought in line with the Regulations as far as is reasonable and practicable. Vessels undergoing a main engine change should comply with the requirements for a new vessel to the extent of the machinery and ancillary systems concerned. 13.2 Record of Particulars relating to the issue of a certificate In determining whether or not a vessel complies with the requirements of the Regulations and should be issued with a certificate, the 'Record of Particulars' (Form FV2) will be a determining factor and should be carefully studied. 22 Rev 0 - 06/04/09 PART C SURVEYS OF VESSELS IN CLASS WITH A RECOGNISED ORGANISATION (to be developed and inserted) 23 Rev 0 - 06/04/09 APPENDIX 1 Guide for Hull Thickness Measurement 1. Purpose The purpose of thickness measurement is to establish, in conjunction with a visual examination, that the condition of the existing structure is, or will be after the required repairs, fit for continued service during the subsequent survey interval. The gauging requirements include measurements, which are used to verify remaining longitudinal strength, transverse sections, as well as measurements of areas known to be potential problem areas, main deck plates and wind and water strakes. Thickness measurements are a tool used to assess ship structure, not a stand- alone method of inspection. Thickness measurements are a confirmation of conditions sighted by the Surveyor. When a Surveyor confirms that a set of thickness measurements are representative of the conditions found, he can only do so if he personally examined and selected the particular areas to be measured, and is satisfied they actually represent the conditions of the structure involved and not the thickness in way of isolated pits or localised corrosion. Local pits and corrosion are to be dealt with as necessary by the Surveyor. 2. The Thickness Measurement Process When an Owner requests attendance for a survey with thickness measurements due, the Surveyor will ensure scantling drawings will be available, either from the Owner or from MSO files. The Surveyor will advise the Owner of the thickness measurement requirements and of the requirement to use an approved company to take the thickness measurements. The Surveyor is to attend the vessel while thickness measurements are being taken in order to advise the Owner of the locations. The Surveyor is to regularly review the thickness measurement results, in order to promptly advise the Owner of any additional readings which are to be taken to confirm marginal conditions or the accuracy of questionable readings. When multiple readings are taken to confirm marginal or questionable readings, the Surveyor will determine and report the single reading which in his / her professional judgement and based on observation, represents the average condition of the plate in question. A corrosion pattern may be localised, may be uniformly present on an individual plate or may cover an entire bottom of a tank. An individual reading does not constitute a corrosion pattern. One marginal reading would require additional readings to be taken and assessed together with close visual examination by the Surveyor for determination of extent of corrosion pattern. When multiple readings are taken or marginal readings encountered, the Surveyor must make an assessment of the average condition based on observations of the structure from visual examination and the gauged readings. 3. Thickness Measurement Review First, the Surveyor is to ensure that all thickness measurement requirements for the applicable survey are met. Any required measurements which have not been taken, will be noted in his report as an item remaining to be completed before the survey can be credited. 24 Rev 0 - 06/04/09 Next, the Surveyor is to check that all individual plate thickness measurement results are within the allowances listed in Table 2 “Steel Wastage Allowances” and Table 3 “Aluminium Wastage Allowances”. For unconverted, conventional type vessels, wastage allowances are to be applied to the as-built thickness. To request a thickness measurement review based on other than as-built thickness or a scantling reassessment, the Owner should contact the Marine Surveyors‟ Office. Finally, the Surveyor is to check the average wastage of the top and bottom transverse sections. If individual plates are to be renewed, this average is to be checked with the renewed plate thickness. For ease of check, the plates and internals are to be averaged separately. The top of the transverse section includes the deck plating, stringer plate and sheer strake. The bottom of the transverse section includes the flat keel plating, the bottom plating, and bilge plating. The internals are those longitudinal members attached to the aforementioned plates. The average wastage is a simple, arithmetic average of the individual plate or internal wastage percentages. For example, assume there are seven (7) plates in a top section with individual plate wastages of 12%, 16%, 18%, 13%, 19%, 11% and 17%. The average wastage of the top section of plating is (12 + 16 + 18 + 13 + 19 + 11 + 17) divided by the number of plates, seven (7), which equals 15.1%. 4. Thickness Measurement Reports Reports are to clearly present the location, original thickness, measured thickness and percent wastage. The attending Surveyor will review the results for accuracy and completeness and endorse the report with the vessel‟s name, the date and his signature to indicate the results are considered representative of the actual condition of the vessel. 5. Thickness Measurement Company Approval Requirements Persons or companies who act at the request of the Owner to take ultrasonic thickness measurements on vessels for statutory surveys, must be approved by a Recognised Organisation or be acceptable to the Minister. The local MSO can provide the Owner with a list of approved companies in that office‟s area. The Department does not recommend or endorse any specific company and it is entirely up to the Owner to select the company. 6. Thickness Measurement Requirements and Locations The thickness measurement requirements for Surveys are based on the conditions found at the time of survey, as well as conditions documented at Paragraph 5.1 of the Guidelines. Thickness measurement requirements for Periodical Survey are based on age of vessel. In all cases, the Surveyors have the discretion to require thickness measurements to supplement their visual examinations where there is any doubt of the structure‟s fitness for continued service. 25 Rev 0 - 06/04/09 The Surveyor will indicate the locations to be measured. Transverse sections should be in one section, not over several frame spaces. The sections should be located where the largest reductions are suspected to occur or are revealed from deck plating thickness measurements. Where possible, locations different from those measured at previous Periodical Surveys should be selected. 7. Modification of Thickness Measurement Requirements In general, thickness measurement requirements of internals may be modified for vessels with acceptable, corrosion-resistant, hard-type coatings, such as epoxy or zinc, providing that after a careful examination, the Surveyor can verify the continued effectiveness of it. No consideration for reduced thickness measurements will be given for soft type coatings. Where there is evidence that the coating is no longer intact (such as heavy staining, blistering, cracking, peeling or bare spots), the Surveyor must require sufficient confirmatory thickness measurement to clearly establish the condition of the internals. Note that in the initial stages of coating breakdown, the corrosion may proceed at a very high rate in the exposed spots due to the abnormal area ratio between the protected and unprotected surfaces. For converted vessels, the Periodical Survey and the thickness measurement requirements are based on the age of the original, retained sections. However, the thickness measurement requirements for the new body sections may be in accordance with Periodical Survey requirements for a vessel of corresponding age. 8. Additional Thickness Measurements and Substantial Corrosion The Surveyor will specify additional thickness measurements in areas of known or suspected wastage. During the thickness measurement process, the Surveyor will also advise the Owner if any additional readings are to be taken to confirm questionable readings or marginal conditions. Substantial Corrosion is defined as, “an extent of corrosion such that assessment of corrosion pattern indicates wastage in excess of 75% of the allowable margins, but within the acceptable limits”. An individual reading does not constitute a corrosion pattern. A single, marginal reading requires additional readings to be taken and evaluated together with close visual examination by the Surveyor in order to determine the extent of the corrosion. For example, assume the individual plate wastage allowance for plates in a transverse bulkhead is 25% and the original thickness of the plate in question was 12mm, the following illustrates the wastage limits: For a gauged thickness of 9.75 to 12mm, the percent diminution was 18.75% (i.e., 75% of 25%) to 0%, therefore, the plate had some corrosion. For a gauged thickness of 9.0 to 9.75mm, the percent diminution was 25% to 18.75%, therefore, the wastage of the plate was in substantial corrosion range. For a gauged thickness of less than 9.0mm, the percent diminution was greater than 25%, therefore, the wastage of the plate was outside the allowable wastage limit and the plate should be renewed. Once a thickness measurement reading reaches a critical wastage range (by substantial corrosion definition, 75% of allowable wastage), the accuracy of that reading is more crucial in 26 Rev 0 - 06/04/09 determining the appropriate recommendation. Accordingly, when substantial corrosion is found, the number of readings must be increased. In assessing the overall condition, it should be borne in mind that where wastage limits are based on a percentage, thinner members would of course reach the limit sooner, assuming the material loss rate per surface is the same. Also, where both surfaces of a member are exposed to the same wastage conditions, the limit will be approached at double the normal rate. For instance, internals in tanks, since they are exposed to corrosion on both surfaces and because they are often originally thinner than the plating in the same area, usually reach the limiting wastage much earlier than the plating. Accordingly, if substantial corrosion is found on plating, additional thickness measurements should be extended not only to surrounding plating, but also to internal members. Likewise, when substantial corrosion is identified on internals, additional thickness measurements are to be extended to other similar and thinner internals. For Example, considering a typical bottom structure: - “Bottom shell plating and longitudinal members are gauged across a transverse section in way of the aft most bay of a wing tank. The transverse section required each plate and longitudinal member to be gauged. The readings identified one bottom strake with wastage in the substantial corrosion range.” The following action would be required: For the one identified strake, the number of readings must be increased. This will require a five-point pattern to be thickness measured on each panel of the strake within the bay. This high density of readings will provide a higher degree of accuracy in determining the corrosion pattern and will provide sufficient data to establish appropriate recommendations for extent of repair, if required. Bottom shell thickness measurements are to be extended. This will require the bottom shell in way of two other bays to be measured with the minimum thickness measurement pattern. If vessel‟s age is 15 years or greater, all bottom plates will have been measured as a baseline requirement. If the minimum thickness measurement pattern indicates wastage in the substantial corrosion range, thickness measurements should be increased to the five-point pattern per panel as above. No internal members were identified with wastage in the substantial corrosion range for the transverse section. However, as internals usually reach the limiting wastage much earlier than the plating, additional thickness measurements should be extended not only to surrounding plating, but also to internal members. This will require in way of the two other bays identified in above, three longitudinals in each bay to be measured with three (3) measurements in line across flange and three (3) measurements on vertical web. Similar action should be taken with regard to bottom girders and brackets and bottom transverse webs. Areas of Substantial Corrosion identified would have to be thickness measured at subsequent Intermediate Surveys. If areas of Substantial Corrosion have been coated with a hard coating and the Surveyor finds the coating is still effective at the time of survey, the confirmatory thickness measurements normally required at that Intermediate Survey may be specially considered by the Surveyor. 27 Rev 0 - 06/04/09 9. Suspect Areas Suspect Areas are areas prone to rapid wastage or having Substantial Corrosion. Special attention should be paid to unprotected salt water ballast tanks, bilge wells, shaft alley recesses, pipe tunnels or duct keels, lower edges of bulkheads, bulkhead stools, exposed hatch covers, hatch coamings and brackets, areas just above joint of tween deck or tank top to side shell plating, horizontal stringers and webs, shell plating adjacent to transverse bulkhead boundary welds, void spaces under boilers, plating in way of steam drains and adjacent to heated tanks, plating in way of areas where drainage accumulates or flows very fast, and panting areas. Plating behind under deck accommodation linings should also be paid special attention. 10. Individual Plate Wastage Allowances The wastage allowances for individual plates are found in Table 1 and Table 2. Guidance wastage allowances for rudders or rudder components are: Rudder side plating and vertical diaphragms: 25 % Rudder top and bottom plating and horizontal diaphragms: 30 % 11. Wastage Compensation and Repair Wasted areas are to be repaired to the satisfaction of the Surveyor or noted as outstanding recommendations in the survey report. Individual plates or structural members that are wasted in excess of allowable limits are to be cropped and renewed. The primary concerns in assessing overall wastage are the hull longitudinal strength and the local buckling strength. Localised wastage and pitting is to be dealt with to the satisfaction of the Surveyor and may not require renewal. Local wastage should be viewed from the standpoint of local buckling, fracture and the potentially serious risk of marine pollution. Localised areas of serious wastage, pitting or grooving may have to be dealt with immediately. Highly localised pitting, usually found in oil tanks, may be cropped and renewed, cleaned and coated with a special coating, cleaned and filled with a special filler, or repaired by welding. The choice of repair method depends mainly on the percentage of the plating surface area that is pitted, the depth of pits and the size of pits. The Surveyor will make the appropriate repair recommendation considering the particular circumstances. For additional information on pitting repairs, IACS “Shipbuilding and Repair Quality Standard” may be referred to. Areas showing signs of load deformation (permanent set) or stress corrosion may have to be reinforced or renewed even though the wastage allowance may not have been exceeded. Partial renewal of a plate is permitted provided the remaining portion is satisfactory. Small inserts should be avoided because fractures frequently develop, probably due to cumulative shrink stress and notch effect at the corners. Preferred renewal is full width, and length no less than the width; or at least half-width and length equal to one plate width or more. For less than full width inserts, the corner that does not land on a seam or butt should be radiused. For local inserts, it is suggested that the minor dimension should never be less than 300mm. 28 Rev 0 - 06/04/09 Replacement plating should be the same, equivalent or higher Grade and substantially the same thickness as the original Rule requirement. Replacement shapes must equal original Rule section modulus (with plate) and sectional area. Substitutions of steel differing from that originally installed, alteration of original structural configuration or change from riveted to welded joints is not to be made without prior approval. Local doublers are not acceptable as a permanent repair or wastage compensation. If such doublers are found, the plating underneath should be carefully investigated and repaired, where found necessary. Where straps are resorted to for area loss compensation of deck or bottom plating area, there must be sufficient material underneath to effectively transmit the load. If used to reinforce a longitudinal strength member, then continuity must be maintained throughout the affected area. Any local plate wastage is to be dealt with by renewal prior to the installation of straps. In general, a strap should be continuous throughout the amidships 0.5L and no more than 1.5 times the thickness of the underlying plating. The strap should fit tightly onto the underlying plating and be continuously welded around the edges; if over 600mm wide, it should also be plug-welded on 300mm centres. Strap ends should taper in width and terminate at least two frame spaces or approximately 2 meters beyond structural changes-in-section (such as hatch ends or superstructure end bulkheads). Where possible, straps should be situated over underdeck longitudinal girders or bulkheads. All proposals for continuous strapping are subject to approval. In any case where elimination of riveted joints or change of structural form is contemplated in connection with renewals, prior approval must be obtained. 12. Wastage Rates – Effects on Thinner Members and Welds In assessing the overall condition, it must be understood that where wastage limits are based on a percentage, thinner members will of course reach the limit sooner, assuming that material loss rate per surface is the same. Also, where both surfaces of a member are exposed to the same wastage conditions, the limit will be approached at double the normal rate. For instance, internals in most ballast tanks, since they are exposed to corrosion on both surfaces and because they are often originally thinner than the plating in the same area, usually reach the limiting wastage much earlier than the plating. Special attention should be paid to the fillet welds attaching internals to the plating, particularly in forepeak tanks and on the underdeck of tanks. The wastage of the heavy deck longitudinals may be relatively low on a percentage basis, but the relatively small fillet welding attaching the longitudinals to the plating may be already wasted sufficiently so as to render the internal member ineffective. Likewise, internal members such as hold frames and end brackets may be subject to necking and grooving corrosion adjacent to connection that will require special attention and thickness measurements. 29 Rev 0 - 06/04/09 TABLE 2 Steel Wastage Allowances Main Deck Plating 25% Bottom Plating 25% Keel Plating 25% Sheer Strake 25% Bilge Strake 25% Side Shell Plating 30% Forecastle 30% Internals and Bulkheads 30% TABLE 3 Aluminium Wastage Allowances Main Deck Plating 15% Bottom Plating 15% Keel Plating 15% Sheer Strake 15% Bilge Strake 15% Side Shell Plating 20% Forecastle 20% Internals and Bulkheads 20% 30 Rev 0 - 06/04/09 APPENDIX 2 IT PAYS TO BE PREPARED FOR YOUR VESSEL SURVEY Quick Guide to Survey Preparation Preparing and presenting your vessel properly for survey will save you both time and money. Forward planning and preparation could make the difference between success and failure. This leaflet sets out useful advice to help ensure your next survey is a successful one. APPLYING FOR SURVEY Apply early to your local Marine Survey Office. Survey Application Form available at http://www.transport.ie/upload/general/11402-0.pdf. Ensure that the details that are supplied on the application form are correct, especially in relation to the vessel name, port of registry, dimensions, tonnage and registered power. Incomplete or incorrectly filled applications may be returned to the applicant. Surveyors will also check the application details against the vessel at the time of the survey. Your survey can begin up to six months before your Fishing Vessel Safety Certificate expires. Organise your survey to limit the number of visits the Surveyor has to make. Most surveys can be completed in two visits. The most efficient order for surveys is an out of water survey followed by an in water survey. However if the vessel is being surveyed for the first time (an Initial Survey), you should arrange for an additional in water survey prior to the vessel being taken out of the water. At this time you can discuss with the Surveyor the survey procedure. Have your Marine Consultant conduct stability checks whilst the Surveyor is conducting the initial in water survey. Survey Check List OUT OF WATER SURVEY A surveyor will check for the following during a survey. Follow the guidelines below to cut down the time the Surveyor spends on board and the need for re-visits. Pressure wash the hull but do not re-paint until after survey. Open up Tanks and Spaces which are to be inspected. Tanks are to be clean and certified gas free and other spaces are to be clean. Ultra sonic tests to be carried out on total hull area and suspect areas whilst Surveyor is present, (on steel vessels). Remove and clean sea valves, both inlets and overboards for inspection. Propeller shaft clearances to be taken. This may be achieved by feeler gauges or by lifting the shaft and using a clock gauge. The Surveyor will then advise if withdrawal/renewal of shaft is required. 31 Rev 0 - 06/04/09 Rudder pintel bearing clearance to be taken. Draft marks to be checked. Wooden vessel. Having a shipwright available at survey time allows the Surveyor to discuss any required course of action with him. Fastenings on wooden vessels will be withdrawn at the discretion of the Surveyor. 32 Rev 0 - 06/04/09 WHAT IS THE SURVEYOR LOOKING FOR? The Surveyor will look at the following areas whilst on board your vessel. The following sections tell you what the Surveyor is looking for when he or she checks these areas. Doing your own checks in advance can identify problems you can sort out beforehand so saving you time and money on the survey itself.

Recognizing the desirability of ensuring the adequate strength of scantlings of portable fish-hold divisions, studies on national practices have been carried out, resulting in the establishment of certain formulae for scantlings, which are recommended to Administrations for their guidance. 2. These formulae represent the average of a wide range of experience covering all types of vessels operating in all sea areas, and in conditions likely to impose the maximum loading on a division. Alternative scantlings might, however, be accepted where experience has shown that these are more appropriate. 3. According to the basic type of construction, the following formulae are recommended for vertical fish-hold divisions: .1 Vertical steel uprights and horizontal wooden boards Minimum section modulus of vertical steel uprights Z = 4ρ sbh2 (1) Minimum thickness of horizontal wooden boards t = 8 ρ sb2 (2) .2 Horizontal steel beams and vertical wooden boards Minimum section modulus of horizontal steel beams Z = 4ρ sHS2 (3) Minimum thickness of vertical wooden boards t = 3.6 ρ sh 2 (4) where: Z = section modulus, in cm3. t = thickness of wooden board, in cm. ρ = density of cargo, in t/m3. s = maximum transverse distance between any two adjacent longitudinal divisions or line of supports, in m. h = maximum vertical span of a column taken to be the hold depth, in m. b = maximum longitudinal distance between any two adjacent transverse divisions or line of supports, in m. H = vertical span of a division which is supported by a horizontal beam, in m. S = horizontal distance between adjacent points of support of a horizontal beam, in m. ∗ Appendix V of the annex of Assembly resolution A.168(ES.IV) incorporating subparagraphs 4(g) and 4(h) adopted by the eighth Assembly. Page 38 Revision 0 10th March 2009 4. In applying the above formulae, the following notes should be observed: .1 The formulae are applicable to longitudinal divisions. Where the divisions are athwartships the formulae should be modified by interchanging s and b. .2 The formulae were derived on the assumption that the loads were on one side only of the divisions. When it is known that the divisions will always be loaded on both sides, reduced scantlings may be accepted. .3 If vertical steel uprights are permanent and well connected at both ends with the structure of the ship, reduced scantlings may be accepted depending upon the degree of security provided by the end connections. .4 In the formula for vertical wooden boards, the full depth of the hold is assumed as the unsupported span, where the span is less the thickness may be calculated using the reduced span. .5 The timber used should be of sound durable quality, of a type and grade which has proved satisfactory for fish-hold divisions and the actual finished thicknesses of boards should be those derived from the formulae. The thickness of boards made from good quality hardwood may be reduced by 12.5%. .6 Divisions made of other materials should have strength and stiffness equivalent to those associated with the scantlings recommended for wood and steel, having regard to the comparative mechanical properties of the materials. .7 Channelways in stanchions to take pound boards should have a depth of not less than 4 cm and the width should be equal to the pound board thickness plus 0.5 cm. .8 Each pound board should have a length not less than the distance between the bottom of the respective channelways into which it will engage minus 1 cm. If pound boards have shaped ends to allow a rotational manoeuvre for easy housing, the extent of end shaping should not be more than allowed by a radius equal to one half the length of the board with its centre at the mid length and depth of the board. 5. Figures 1 and 2 illustrate the application of the formulae. Page 39 Revision 0 10th March 2009 Page 40 Revision 0 10th March 2009 Page 41 Revision 0 10th March 2009
