The 100 mile Forties pipeline system transports approximately 450 000 bpd of oil from 80 oilfields. As reported by The Telegraph: “It transports oil from the unmanned offshore Unity platform in the North Sea to the onshore terminal at Cruden Bay near Aberdeen. From here 130 miles of onshore pipes carry the oil to the Kinneil terminal near Ineos’s Grangemouth oil refinery.”
