Wartsila 32 Dual fuel control upgrade
The Foinaven is a Floating Production Storage and Offloading (FPSO) vessel operating in the West Shetlands. The vessel is 250 meter long and 34 meter wide and started oil production in 1997 with a max capacity of 140,000 barrels of oil per day. The vessel is powered by four Wartsila 16V32GD and four Wartsila 18V32GD engines. Each engine drives a medium voltage generator with a combined output of approximately 50MW.
The engines are able to run on diesel or high pressure gas (350 bar) up to full load. The engines can also switch between fuel without interruption to the power output. The main engine controls, multipoint injector drivers, high pressure electronic rail valves and main engine governor were originally supplied by Woodward.
After operational contract renewal, the Teekay Shipping Corporation approached Turner ECS to investigate parts obsolescense and field service supportability on the long term (minimum 10 years) to guarantee safe and reliable operation. After conducting a site survey it became clear that the Woodward main engine control (Netcon) and multi point driver modules (EFIC/EFID) would not fall within the new supportability requirement and had to be replaced.
