Wärtsilä wins production platform power contract
Wärtsilä has been awarded a contract from BP to deliver an integrated package of auxiliary diesel generators totalling 15.3 MW for the Thunder Horse offshore project in the Gulf of Mexico. The power plant will be installed on the production, drilling and quarters platform Thunder Horse PDQ being built in Korea.
The integrated package of auxiliary diesel generators is to supply the hull and drilling rig loads, the emergency services, and the fire pumps, with control systems for all three services.
The auxiliary diesel generators are powered by two Wärtsilä 18V26 engines, each rated 5580 kW at 900 rpm. The emergency generator has a Wärtsilä 12V200 engine, rated at 2100 kW at 1200 rpm. Two Wärtsilä 6L20 generating sets, rated 1020 kW at 900 rpm, provide independent power for the emergency fire water pumps.
The Thunder Horse field is the largest oil and gas discovery to date in the Gulf of Mexico. It is located approximately 150 miles south-east of New Orleans. The field will be developed by BP, with ExxonMobil owning a 25% interest in the field development. BP will act as the field operator. The hydrocarbons from this field will be produced using the "Thunder Horse PDQ" platform. Displacing 129,000 tonnes, this will be the largest semi-submersible production platform in the world. It will be delivered from Korea in 2004.
The Wärtsilä engines will provide essential power for all hull and drilling rig related services, allowing the platform to be commissioned before it leaves the shipyard. Once the platform arrives at the U.S. Gulf coast, the Wärtsilä engines will provide onboard power while the topside process modules are integrated with the platform hull and for commissioning of the topside systems.
