The Petrojarl Foinaven is an offshore production system specially designed for oil production in the ultra-harsh environment of the North Sea and North Atlantic margin. It is designed to stay connected to the production wells in the 100 year West of Shetland environmental condition.

The ship’s production facilities comprise two parallel two stage separation trains separating crude, gas and produced water. The stabilized crude is temporarily stored onboard for subsequent offloading to shuttle tankers. The produced gas is used for generation of electricity, fuel to boilers, gas lift and the remainder is exported to the Magnus Field for enhanced recovery purposes. The reservoir pressure is maintained by a water injection system.
