Power generation modules

Finland-based Wärtsilä is set to supply topside power module solutions for a floating production, storage and offloading (FPSO) vessel to be deployed at the Kraken oilfield in the UK sector of the North Sea.

The engineering, procurement and construction (EPC) contract was awarded by Malaysia-based international offshore oilfield services provider Bumi Armada’s wholly owned subsidiary Armada Kraken, in December 2013.

Under the contract, Wärtsilä, which provides lifecycle power solutions for the marine and energy markets, will deliver two identical 62MW power generation modules.

Each module, designed by Wärtsilä Ship Design, will accommodate two 16-cylinder Wärtsilä 50DF multi-fuel engines with generators, waste heat recovery units and all related fuel, oil and air, and other utility systems.

According to the company, the engines can be operated on various fuel types, including treated well gas, heavy crude oil and marine diesel oil (MDO).

Compared with conventional technologies, the gas-fired power solution is said to produce significantly lower levels of CO2 emissions.

"Wärtsilä plans to deliver its equipment mid-2015, while the FPSO is slated to start production at the Kraken field in 2016."

For FPSO conversion, Bumi Armada will be using a recently built Suezmax tanker with a storage capacity of 600,000 barrels.

Wärtsilä plans to deliver its equipment mid-2015, while the FPSO is slated to start production at the Kraken field in 2016.

Wärtsilä Ship Power vice-president solutions Magnus Miemois said: "This engagement with Bumi Armada endorses the fact that our integrated power module solutions offer the critical fuel flexibility and the high levels of efficiency and availability that successful offshore operations demand."

Over the coming 25 years, approximately 140 million barrels of heavy oil are expected to be extracted from the Kraken field.
