Subsea 7 announced the award of a very large contract by Woodside to Subsea Integration Alliance(3) for the Sangomar Field Development Phase-1 project located in the Sangomar Offshore and Sangomar Offshore Deep oil blocks, offshore Senegal. This contract was initially awarded in December 2018 subject to final investment decision, which has now occurred.
The project work scope covers the engineering, procurement, construction, transportation and installation of the SURF system and associated subsea production systems (SPS). The development will include 23 wells, 107 km of rigid flowlines, 28 km of flexible risers and jumpers, and 45 km of umbilicals in water depths between 700 metres and 1400 metres.
Offshore activities will take place from 2021 to 2023 using Subsea 7’s reel-lay, flex-lay and light construction vessels.
The Subsea Integration Alliance team established during the Front End Engineering Design (FEED) phase will now transition into the full EPIC phase based at Subsea 7 Global Projects Centre (GPC) in Sutton, UK. SURF engineering will be performed by Subsea 7 GPC centres in Sutton and Suresnes, France. A base in Senegal will support the offshore campaign and conduct site receipt testing and equipment storage.
