Lesson plan
Douglas Complex
The Douglas Complex is a high system of three linked platforms in the Irish Sea, 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. Oil from the Lennox, Hamilton, and Hamilton North unmanned satellite platforms is received and blended at the complex. Fluids from the Lennox installation via the gas pipeline are treated on the Douglas installation in the 3-phase (oil, gas and produced water) Lennox Production Separator. Following separation, gas flows to the Offgas Compressor suction manifold. Oil is directed to the Oil Stripper where the liquid is stripped of sour gas using a counter-current flow of stripping gas. Produced water from the separator is directed to the Produced Water Hydrocyclones where hydrocarbon liquids are removed prior to overboard disposal.…
