The Douglas Complex is a 54-metre (177 ft) high system of three linked platforms in the Irish Sea, 24 kilometres (15 mi)[1] off the North Wales coast. The Douglas oil field was discovered in 1990, and production commenced in 1996. Now operated by Eni, the complex consists of the wellhead platform, which drills into the seabed, a processing platform, which separates oil, gas and water, and thirdly an accommodation platform, which is composed of living quarters for the crew. This accommodation module was formerly the Morecambe Flame jack-up drilling rig.

The Douglas Complex is also the control hub for other platforms in the area, and provides power for all platforms. It also offers recreational, catering and medical facilities for up to 80 personnel.[2] Oil from the Lennox, Hamilton, and Hamilton North unmanned satellite platforms is received and blended at the complex.[3]

Gas is sent through a pipeline 33.5-kilometre (20.8 mi) long to a processing plant at Point of Ayr, in Flintshire, North Wales. After processing, almost the entire output is sold to E.ON to fire the combined cycle gas turbine power station at Connah's Quay, on Deeside, in Flintshire. Oil produced in Liverpool Bay is sent through another pipeline, 17 km long, to the Offshore Storage Installation, a permanently anchored barge which acts as a floating oil terminal, capable of holding 870 thousand barrels (~1.2×10^5 t) of oil. From the floating terminal oil is transferred to tankers approximately once every month.[2]
