Royston completes engine overhaul on FPSO vessel

A team from diesel power specialist Royston Limited has completed the important engine overhaul on the Bluewater-owned Haewene Brim offshore floating production, storage and offloading (FPSO) vessel. The 252m, 103,000dwt facility has operated in the Pierce Field in the UK sector of the North Sea, since 1999 on behalf of Shell UK Exploration and Production. Last year vessel was also linked to the the Brynhild field, operated by Lundin, located in the Norwegian sector.The Haewene Brim is powered by main generating sets consisting of four 5.2MW Wartsila W46 medium speed diesel engines.Initially working alongside a Wartsila team, the scheduled 48,000 hour service on the first engine required the Royston engineers to completely dismantle the engine and overhaul the cylinder heads and liners, pistons, con rods, cam shafts and bearings.The service and overhaul started earlier this year, but was halted when adverse weather conditions and 100mph winds caused the evacuation of non-critical personnel from the platform.On resumption of the engine overhaul, damage to the crankshaft journal bearings was identified required remedial machining work to be undertaken in-situ on the vessel. Royston engineers remained on board to oversee and assist with this work and resumed the main engine service when the crankshaft was repaired.Following the specialist repair of the crankshaft, Royston completed the main engine overhaul with full commissioning and a 100% load run.
