Frigg Sealines Abandonment

Decommissioning FPSO

Key Asset Abandonment Study

Customer: Total UK Location: North Sea

Customer: Confidential Location: WEst Africa

Customer: Confidential Location: Confidential

As part of the offshore abandonment scope, all sealines within the platform safety zones needed to be removed or otherwise made safe for other users of the sea. Associated rock berms were to be removed or leveled. Final seabed configuration must have been acceptable for interaction with fishing equipment.

A decommissioning plan, cost estimate and schedule for an offshore oil platform, removal of remote subsea wells, pipelines and FPSO in deepwater West Africa was developed. The work included a cleaning plan to remove hazardous waste from the facilities and FPSO and the engineering and operations support for decommissioning and demobilization of the FPSO and subsea equipment. WorleyParsons provided engineering and analysis to support the disconnection of the risers, umbilicals and mooring legs from the FPSO during the planning and execution stages. WorleyParsons executed the marine consultancy and offshore operations supervision during the disconnection and demobilization operations offshore.

WorleyParsons performed a decommissioning and abandonment plan of offshore assets. The study consisted of a detailed cost estimate that evaluated the removal options, regulatory framework and degrodation issues associated with decommissioning (abandonment and removal) of 3 separate installations. Assets included 13 subsea wells and 6 platform wells, Production Platform, pipelines (10”, 9”, and 12”), umbilicals, manifolds, and an onshore gas processing plant.

INTECSEA’s scope included assessment of pipeline rockberm overtrawlability, risk assessment for abandoned pipeline, pipeline recovery analysis, market survey of rock spreading tools and capability, and recommendations of spreading scope and method.
