Woodside advances Sangomar development, FPSO moves for topsides integration
Woodside Energy Ltd. completed construction of the FPSO for Sangomar Phase 1 field development offshore Senegal. The vessel is now being relocated to Keppel Offshore & Marine Ltd.’s Tuas Shipyard in Singapore. Keppel will complete topsides integration and support pre-commissioning and commissioning activities for the vessel.
The FPSO is a converted Very Large Crude Carrier and has been named after Senegal’s first president, Leopold Sédar Senghor. It will have a capacity to produce 100,000 b/d of oil.
Woodside let the FPSO supply contract to MODEC Inc. in 2020. Hull and marine works, external turret and topsides module installation, and conversion work on the vessel were completed by COSCO Shipping Heavy Industry (Dalian) Co. Ltd. The topsides modules were fabricated by both COSCO and by BOMESC Offshore Engineering Co. Ltd. in Tianjin. The external turret mooring system was fabricated by Penglai Jutal Offshore Engineering Heavy Industries Co. Ltd.
Phase 1 of Sangomar field development—Senegal’s first offshore oil project—is currently about 70% complete. Development includes the FPSO, 23 wells, and supporting subsea infrastructure to tie-in subsequent phases.
Sangomar field, formerly known as SNE field, was discovered by FAR in November 2014 in 1,100 m of water about 100 km south of Dakar. Recoverable oil reserves are estimated at nearly 630 million bbl.
Woodside is operator with 82% interest. Société des pétroles du Sénéga (PETROSEN) holds the remaining 18%.
