Primary drivers of this project were safety in all aspects of execution with minimal interruption of oil production. Successfully completed with an exemplary safety performance and only 37 days in dry-dock, Hśwene Brim resumed crude oil production within 3 weeks after leaving drydock and second oil and gas was achieved shortly thereafter. Full water injection was achieved December 21st.
The upgrade work took close to one million manhours with a scope of work that included installation of water injection facilities weighing over 1000 tons along with modifications to existing vessel systems, class and flag survey works. Fabrication of the new facilities took place at both McNulty's, and A&P Tyne facilities.
Water injection facilities were added to the FPSO in order to further develop the Pierce field located in the central North Sea, 280 km east of Aberdeen. The new facilities will inject up to 95,000 barrels per day of seawater into the field reservoir to increase pressure and enhance production levels.
"This project clearly demonstrates the flexibility of modern FPSO vessels. While a fixed production platform would have been out of production for at least 4 months and would have required an expensive floating offshore crane and hotel platform, the Haewene Brim FPSO could easily disconnect and sail under its own power to the shipyard in order to undergo these fast track modification works," stated Jesse van de Korput, Vice President Floating Production, Bluewater Energy Services B.V.
