TheBrent System pipeline transports oil from theNorth Seaoilfields viaCormorant Alpha to theSullom Voe Terminal inShetland,Scotland.[1] Since 3 August 2009, it is operated byAbu Dhabi National Energy Company replacing the previous operatorRoyal Dutch Shell.[1][2] The Brent system is jointly owned by 21 companies.[1]
Oil is transported from 20 oilfields, including:
The Cormorant A to Sullom Voe pipeline is 36 inches (910 mm) diameter steel (API 5L X60) of 147 kilometres (91 mi) in length. It has capacity of 100,000 barrels per day (16,000 m3/d).[1] The Brent C to Cormorant A pipeline is 30 inches (760 mm) in diameter and 35 kilometres (22 mi) long.
