From Australia (RW): Subsea 7 has won a contract from Woodside Petroleum for the Persephone (SEN, 31/18) development - Work Pack 2 covering fabrication, subsea installation and diving services on the North West Shelf (NWS).
The project involves two wells tied into a subsea production manifold and gas production tied in to the existing North Rankin complex 7km away.
Subsea 7’s contract covers fabrication, transportation, installation and pre-commissioning activities, with additional decommissioning and pipeline suspension work in the Echo/Yodel satellite field to the Goodwyn A platform.
Project management and engineering will start immediately in the group’s Perth office. Offshore operations using the diving construction vessel Seven Eagle will begin during fourth-quarter 2015.
The NWS partners approved development of Persephone last November. Total investment will be A$1.2n with the field due onstream in early 2018.
A few more details on the Woodside FEED contract with Wood Group Kenny for the flowline system and procurement support for its Greater Western Flank (31/22) phase 2 development on the NWS.
GWF2 is the next phase of gas supply to the existing NWS project after Persephone. It includes six fields - Keast, Dockrell, Sculptor, Rankin, Lady Nora and Pemperton.
The new contract follows completion of the preliminary engineering of the GWF2 rigid flowline basis of design phase.
Scope of work for the new award includes engineering and procurement support services for the 16in CRA rigid flowlines, FLETs, inline tee assemblies, mid-connection structure and tie-in spools.
The focus of the FEED is to develop the flowline system prior to final investment decision in the second half of this year.
