NEWCASTLE-UPON-TYNE, UK – Royston has completed the overhaul of engines on the FPSOHaewene Brim for operator Bluewater Services.

Engineers undertook a 16,000-hour service on the Wartsila W6L46 diesel engines onboard the 252-m (827-ft) long, 103,000-dwt Samsung-built vessel as part of a refurbishment and refit of critical fuel and power systems.

The FPSO has been operating on Shell’s Pierce field in the UK North Sea. It is powered by main generating sets comprising four 5.2-MW Wartsila W46 medium-speed diesel engines.

Royston’s team dismantled the engines and performed maintenance and repair work on fuel systems, bearings, pistons and connecting rods, cylinder liners and heads, valves, camshafts, drive gears and turbochargers.

The HT, LT water pumps and main lube oil pump were replaced and new turbochargers fitted to two power units.

A new section was fitted to the no.2 engine to counter wear on the camshaft wear, and new bushing and bearings and an exchange governor were fitted to the fuel rack and control systems to improve performance.

Then a period of comprehensive testing, involving full commissioning and a 100% load run was carried out.

TheHaewene Brim was originally built as a multi-purpose shuttle tanker and was converted to an FPSO at the Aker McNulty yard in Newcastle in 1998, ahead of deployment on the Pierce field.

A water injection topsides module was added in September 2004.
