Although the location is described as in the continental shelf block, in practise Foinaven is the first development made beyond the actual reach of continental shelf.
Oil is produced by subsea wells via a manifold, which passes through rigid flowlines and then flexible risers into a floating production, storage and offloading system (FPSO). Surface process facilities consist of two parallel oil separation and gas compression trains with a combined liquid handling capacity of 145,000 bbls per day of crude oil and 114 million standard cubic feet (scf) per day of associated gas.
The FPSO, Petrojarl Foinaven, which is operated by Teekay Petrojarl, has an overall length of 240m and an oil storage capacity of 300,000 bbls. It is permanently stationed in the field and the crude oil is exported by shuttle tankers. Oil is exported primarily to the Flotta oil terminal in Orkney with smaller amount is going to Tranmere Oil Terminal on Merseyside.
Approximately half of the produced associated gas is used for enhanced oil recovery of the field. Another half of natural gas is exported through the West of Shetland pipeline to the [[Sullom Voe Terminal]. Some of the exported gas is used as fuel in the Fortum operated Sullom Voe power station. The remainder is enriched with LPGs and exported to the Magnus platform for enhanced oil recovery in Magnus field.
