Port of Mossel Bay INTRODUCTION Mossel Bay has always been a fishing port of substance with limited commercial cargo activity. More recently however, it has started to service the oil industry as well and today these two industries play a major role in the development of the port. Since the launch of the Mossgas project in 1987 for the production of synthetic fuels and by-products, Mossel Bay has been on the brink of great industrial development. An excellent road and rail network connects Mossel Bay to the consumer markets and industrial zones of South and Southern Africa. Owing to the relatively small size of the port, it is supported by the Port of Port Elizabeth in various specialised fields, i.e. industrial relations, training, financial management, equipment and infrastructure procurement. Description of Position Situated halfway between Cape Town and Port Elizabeth, Mossel Bay is the only South African port that operates two offshore mooring points within port limits. It also serves as the oil rig supply boat base Longitude and Latitude Latitude 34° 08’S Longitude 22° 08’E Special Features The Marine Tanker terminal Single Point Mooring Buoy (MTT) is situated at Voorbaai, an open, unsheltered roadstead, in a depth of about 21 metres of water. FUTURE DEVELOPMENTS Traditionally known as a fishing port, the port also handles the oil industry, especially the oil from gas operations of PETROsa. Various options for its future development are being investigated to include fish processing plants and leisure activities. WEATHER AFFECTING PORT Prevailing winds, south-easterly and south-westerly. Wind direction and velocity are subject to rapid change without warning. PORT AUTHORITY FUNCTIONS Radio/Port Control Mossel Bay Port Control operates on a limited basis. The port’s control centre is manned from 06:00 to 18:00 daily. An NPA’s watchman is employed during 18:00 to 06:00. Limitations e.g. Harbour Entrance Depth The entrance channel has a depth of 8 metres. Ships intending to anchor in the bay must keep clear of the approach channel. The maximum draught for the port is 6,5 metres where MGO and water are available. Pilotage NPA provides pilotage services for all vessels utilising the port or offshore facilities. The rendezvous position with the pilot launch is 2 miles northeast of Cape St. Blaize. The mooring launch is used as the pilot vessel for the pilot and other personnel to board from, and for passing the pick-up rope to the ship. Pilotage is compulsory, however, if the Port Captain is satisfied that the master of the vessel is competent to navigate safely within the limits of the port without the assistance of a pilot, he may grant permission to do so, providing that the vessel is less than 70 metres in length, a regular caller, excluding tankers. Ballast Requirements All ships arriving at the facility are required to have sufficient ballast to give a safe draught for manoeuvering. This should be at least 25% of SDW. Ships arriving with insufficient ballast may be required to increase ballast if the NPA pilot considers it necessary to do so. There is a shore ballast water facility available that is suitable for the reception of WHITE PRODUCT CONTAMINATED ballast only. This ballast may be discharged at the buoy through one of the floating hoses, but only after consultation with the Loading Master. All non-segregated ballast can be discharged to the shore reception facility and may produce no black oil contamination. The Ship’s Master shall ensure that not less than 25% of the summer deadweight of ballast or cargo is on board during loading operations at any time. The requirement is to prevent too high a vertical loading on the buoy turntable bearing during the initial stages of loading and to ensure that the vessel has good manoeuverability at all times should it be required to leave the buoy. Mooring Ship’s ETA must be sent to the ship’s agents 72, 48, 24 and 12 hours prior to arrival. On arriving for berthing, the NPA pilot will board the ship approximately 1 – 2 miles to the east of the facility, or at the discretion of the pilot by radio. The pilot will then advise the Ship’s Master on the mooring operation by discreet use of the helm and engines. Prior to the pilot boarding the ship, two heaving lines and a messenger rope should be made ready on the fo’c’sle head. The derrick should be made ready on the port side. A pilot ladder, rigged with two manropes, is required to be deployed 2 metres above the waterline. Should the freeboard exceed 9 metres, a combination of accommodation ladder and pilot ladder will be required. A tanker basket containing tools and equipment for the connection of the hoses is required to be lifted on board. On the close approach to the buoy, the mooring launch will pass to the ship a mooring pick up rope by connecting the ship’s messenger line to it. The ship will then heave on the messenger until the pick up rope is on board, which will then be heaved up until the chafe chain comes through the bow stopper and the ship is secured. When this operation is complete, the floating hoses will each be connected to previously selected manifolds. The connection is made by the use of bolts to the 8” manifold flanges and the hoses will be supported by ”hanging off” chains to suitable eye pads on the deck opposite each connection. In order to avoid damage to the submarine pipeline and the SPM anchor chains, the ship’s anchor will not be used under any circumstances and will remain secure during berthing operations and for the whole period that the ship is moored to the buoy. Tug Assistance Extensive towage and salvage resources (operated by private enterprise) are available and tug facilities are also utilised for sea rescue and salvage operations. One small tug with a HP of 1400 is available to assist vessels berthing and unberthing. The port provides a berthing gang of three to assist berthing and unberthing, for whom accommodation is required on board. The BTV will attend to the hoses and will remain on the station in the vicinity of the buoy as the diving support and pollution control vessel. The BTV has a capability of towing and is able to hold the ship off the buoy if required. A loading master and a tanker team consisting of three divers and deck watch all remain on board for the whole loading operation. Accommodation is required for these personnel. Working Hours Berthing of tankers at CBM and SPM during daylight hours only. Unberthing from SPM, 24 hours a day. MARINE SERVICES Pollution Control The port is equipped with an oil-containment boom of 150 metres in length, a skimmer and oil dispersing equipment. Fresh Water Supplies Fresh water supplies are available at all berths. Air Supply A constant 700kPa air supply is available at the slipway between 06:30 and 16:00. Bunkering Marine diesel is provided at quay nos. 2, 3, 4 and 5 and at the Vincent Jetty Divers A full diving service is offered by professional divers equipped with modern equipment and marine expertise. Services that are undertaken include the following: ● Hull inspections and cleaning ● All general repairs ● Underwater welding and cutting ● Underwater photography ● Salvage work including use of air bags ● Construction work Telephones Telephones are available for ships from the telecommunications company, Telkom. The request is directed via the ship’s agent. Electricity Electricity is available on application at all berths. The supply is 380/220V 3 phase 4 wire at 50Hz. Rates are available on application. Refuse Removal Service A refuse removal service is available free at all berths on request from the Port Captain. All commercial vessels are encouraged to make use of this service for galley refuse. Chandlers and Stevedores These services are provided by private enterprises. Transport (Internal/Rail/Road) The port has direct transport links with the main consumer markets and industrial zones in Southern Africa. Railways link the port with the Gauteng area, as well as South Africa’s northern neighbouring states. PORT FACILITIES The Port of Mossel Bay is operated on a common user basis and is managed by National Ports Authority who provides and maintains infrastructure as well as the superstructure. Ships are served on a first-come-first-served basis There are two off-shore mooring points within the port limits: the Single Point Mooring (SPM) has been commissioned primarily for the export of Mossgas products, while the oil industry terminal and submarine pipeline which has been used until recently for the import of fuel into the area, is now being used for the export of Mossgas products. Berths Quay No. 4 can accommodate vessels with a maximum length of 130 metres and a draught of 6,5 metres. The handling of cargo is done by marine personnel. The port operates one slipway for the repairing of vessels up to 200 tons. The fishing industry is the biggest user of this facility. Mossel Bay is the only port in South Africa that has a C.B.M. and S.P.M. within port limits. C.B.M. (Cantenary Buoy Mooring) The size of vessels presently allowed on the CBM is 32 000 DWT with a maximum draught of 12 metres and a maximum length of 204 metres. Berthing and unberthing will be carried out during daylight hours only. The cut off time for berthing is 4,5 hours before sunset. Sailing is 1,5 hours before sunset. Both anchor winches should be operational, capable of working independently and have a minimum chain length of at least 10 shackles. The vessel should be equipped with sufficient winches to enable it to connect six ropes from the stern of the vessel, two to each buoy ashore. Winches should also be available forward of the accommodation to handle the breast ropes port and starboard. 10 full coils (220m) 64mm diameter paydrop ropes or comparable floating ropes with a minimum breaking strain of 64 tons are required. S.P.M. (Single Point Mooring) This is an Imodco type Single Point Mooring Buoy with a 3 hose system, which may be used simultaneously. The buoy is 8,5 metres in diameter, with a freeboard of 1,6 metres and painted yellow in colour. The vessel must be fitted with an O.C.I.M.F. type bow stopper designed to take 54mm chains. While on the buoy, the vessel’s trim must not exceed 3 metres. During adverse weather the Loading Master may require the vessel to have less trim. Berthing will be carried out during daylight hours only. For vessels arriving at the SPM, the cut off time for berthing is 1,5 hours before sunset, weather permitting. Limitations Berthing will be limited to wind speeds of less than 25 knots and/or sea swell not exceeding 2m or in accordance with the advice of the NPA Pilot. Berthing on to the buoy will only be permitted in daylight. Equipment and Handling Rates The port owns a number of mechanical appliances including two forklifts. The following services are available at competitive tariffs for private work: • A truck mounted crane, with a maximum lifting capacity of 35 tons, is mainly used for maintenance to equipment and handling abnormal loads within the Mossel Bay area. • Forklifts with a lifting capacity of 3 and 4 tons • A guillotine and plate bending machine with a capacity of bending and cutting a 13mm x 4m steel plate • general machining, welding and rigging services MARINE TANKER TERMINAL Loading Hoses The hoses are 8” internal diameter and the ends are fitted with 8”x 8 hole O.C.I.M.F. 150 pound flanges for the manifold connection and butterfly valves which must be locked in the open position during the whole operation. Hoses must be suitably secured with hanging off chains on the hoses, made fast to either bollard or pad eyes at the manifold. The hoses will be suitably suspended from the ship’s derrick, which must have a minimum SWL of 5 tons. Distance from the vessels manifold rail and this requirement must be taken into account when planning the cargo operation. Mooring Hawser Consists of 45m x 144mm diameter braidline nylon with a 45m x 64mm polypropylene pick up rope. Between the mooring hawser and the pick up rope is a length of 54mm stud link chain designed to be accommodated in an O.C.I.M.F. tongue type bowstopper with which all tankers loading at this terminal must be fitted. Loading Whilst moored at the buoy, the ship is required to maintain an efficient cargo loading and deck watch. While the ship is in berth, the Ship’s Master is entirely responsible for ensuring that the ship does not come into contact with any part of the buoy. When the ship is ready in all respects for loading, the Ship’s Officer in charge must inform the Loading Master. Loading will be started at a slow rate and gradually increased until the agreed loading rate is reached. Loading rates may vary at any time during loading. In case of emergency, immediate stopping of all loading can be accomplished. At the time of topping off, the Ship’s Officer on duty should request the Loading Master to reduce the loading rate prior to any valve closure in order to avoid any excess pressure on the loading hoses. At the final stage of loading, the rate will be reduced at the tank farm ashore, in such a manner as to allow sufficient time to top off accurately without endangering the hoses or risk of spillage. The ship must be ready to move under her own power with engines available at short notice throughout her stay at the facility. Unless the Pilot’s or Loading Master’s prior agreement has been obtained, the ships propeller shall not be turned ahead when moored at the buoy. Loading Rates Whilst the facility has been designed for maximum operating pressures of 1 200kpag for both the distillates and ballast lines and 1 500 kpag for the petrol line at a maximum operating temperature of 30°C, the pressure at the ship’s manifold will not exceed the maximum permitted by the ship. Pump rates and permitted line pressures will be passed to the tank farm by the Loading Master after consultation with the Ship’s Master.
