1SHIPYARDS: Differences between Tankers and FPSO Specification Dr. Alwyn McLeary,Senior Surveyor, Lloyd’s Register ASIA, Singapore Office,(+65)
2Presentation (20mins) Discussion (10mins) Outline a simplified model representing the FPSO Classification processValidated the proposition that there is a lack of agreement between the shipyard tanker/FPSO specificationsIdentify the key issuesIdentify the gapsDiscuss the progress to date in closing these gapsOutline a way forward

5Proposition: there exists a lack of agreement between shipyard tanker/FPSO specifications? YES/NO Depends who you ask?Generally an “interface” issue (Discipline Project Management)Hull (shipbuilding standards + FPSO-Specific Loadings)Everything else (offshore standards)But majority of the project assembled in a shipyardRegulatory Issues Govern
6Key Issues Regulatory Requirements Interface (problems on previous projects)PhysicalCode/SpecificationContractualFPSO-Specific Loadings based approval (Site- & Operational-Specific Loadings)
7Regulatory Requirements Coastal State Authority and National Authority (National Administrations) requirements regarding applicable codes and standards (and dates/versions) govern and requires to be defined at the outset (e.g. SOLAS, MARPOL, Loadline, Tonnage). PMA?If the vessel will disconnect and sail under own power then there may be two sets of requirements to be met (will require to be Flagged). The most onerous for individual systems will govern.At present no clear universal Regulatory requirements for FPSOs established.
8Interface Problem Areas Escape and access routes, particularly configuration of ladders, etcTank entry requirements (in operations), PMAIs MARPOL, SOLAS and LOADLINE applicableNDT requirements based on code compliance at interfaceTolerances at interfaceHazardous Area definitionDrgs. with lines detailing the extent of responsibility?

11GapsTendency to “re-invent the wheel” (not learning from previous projects)80% of Problems due to 20% of Causes (Ref. 1), Project Management and Contracting are Key ElementsHarmonisation of Regulatory RequirementsSpecification Definition (defining interfaces), FPSO/JTP Future AlignmentInterface Management (point 2 above)Physical, Code, ContractualRef. 1: “Capturing Lessons Learned During FPSO Projects”, JR Still, The Naval Architect, January 2004, pp19-22.
12Progress in Closing Gaps Lloyd’s Register Group works closely with FPSO clients to identify potential interface problems at an early stage in the project (e.g. FEED Review).Continuous Rule development and internal R&D activities as well as participation in various JIPs over a number of years (e.g. FPSO-Specific Loadings Project, + future planning of alignment with JTP).Preparation of Guidance Notes expanding Rule requirements and identifying important considerations (e.g. LR Group Guidance Note “FPSO INSTALLATIONS – AN OVERVIEW OF REGULATORY ISSUES”, OS/GN/99001).
13Way Forward Industry Driven Harmonisation of Regulatory Requirements Lessons Learnt Exchange Between FPSO Owners/Operators (FPSOForum is probably already effective in this area)Alignment of Future JTP based Tanker Rules and FPSO Design Apprasial Processes (Increased Transparency in Loading Assessment)
14Summary FPSO’s - NOT JUST A TANKER WITH SOME EQUIPMENT ON DECK! REGULATORY ISSUES GOVERN (NO CLEAR SET OF REGULATIONS APPLY)MANAGEMENT OF VARIOUS INTERFACES VERY IMPORTANTFPSO-SPECIFIC LOADINGS ALIGNMENT TO FUTURE JTP RULES?
