              Optional page N/A added to options Yes/No. - Reporting of optional issues delete from
              Assessment page.
              Structural question after establishing class -removed since structure is USCG issue.
    24-Mar-09 Add comment to characterize estimate and calculations in Structural Factor.
              Location:: Brackets around scour issue (Max bearing area of spud can + 5ft on sand) for
              clarity
              Location: note added to explain answer after mat rig on <100 psf shear strength.
              Metociean: Max W.D. Rating removed from metocean page - irrelevant
              Genotech: Remove requirement for FofS of 1.2 in Survival storm on sand - FofS for Survival is
              Max Airgap in Factors!p6 =62 not 62.5; Structures Tab - G26to G34 formula AE11 changed to

   NOTE: This Checksheet does not constitute a rigorous engineering approach to safety. It merely provides
   a draft Checksheet for Permitting with whatever benefits/limitations that apply to that process. It in no-way
   confirms that the jack-up is suitable for the location. This is a Draft Checksheet and further
   calculations/information is required after suitable explanations are provided as requested herein.
   The User of this document should check accuracy and interpolation of any industry curves (e.g. API 95J,
   API 2 Int-Met, GoM Annex etc) to verify correctness and accuracy. prior to using.

              API 95J calls for information on the location if a jack-up has operated there before. Such
              information may include location, penetrations and footprint dimensions. Any anomalies
              left by the previous rig's operations should be provided.




              This information is requested because the surface soils may have changed for surface
              soils (mat rigs) and measurement techniques may have changed. No specific
              requirements are made other than provision of the date when the information was
              The distance between the information source and the required site has been set at a
              max of 1000 ft as a screening tool. Depending on the site and Consequence level, the
              distance may need to be decreased for the site specific location or for future revisions.

              The suitability may be best evaluated based on the characterization of the information.
              Pile driving records are of minimal use for a mat rig; surface samples have limited use for
              independent leg units and new records give more confidence than old records.




              Geotech information may be valid at a greater distance than 1000 ft if tied back with
              shallow seismic information.




              It is important to note who completed the Checksheet /or approved it so that if questions
