[2] FPS consists of a 36-inch (910 mm) pipeline originating at APA Corporation's Forties Charlie platform.
The pipeline carries crude oil 169 kilometres (105 mi), routing through the Forties Unity riser platform, to the terminal at Cruden Bay.
From there unstabilised crude is co-mingled with natural gas condensate from the St Fergus terminal and pumped to the processing facility at Kinneil, Grangemouth.
The onshore pipeline has three intermediate pumping stations at Netherley, Brechin and Balbeggie.
It was formerly owned and operated by BP, which retained the asset after selling the Forties Oil Field to APA Corporation in 2003.
