white rose oilfield development application - Husky Energy

While facility designs are very preliminary, it is expected that the processing requirements will be basedon a single processing train and will not require any unconventional facilities. The oil will be stabilizedin a conventional separation train and de-watered in an electrostatic coalescer. The gas will becompressed for reinjection in a multi-stage compression train. The proposed configuration comprises athree-stage compression system driven by gas turbines.Accommodations will be located either at the stern or at the bow of the vessel. The pallets containingoil and gas will be located at a safe distance from the accommodations. Typical personnel levels willrange from 45 to 50 permanent crew up to 80 to 85 with temporary crew. The accommodationrequirement for the FPSO will consider the requirements for normal operation and also offshore hook-upand commissioning and maintenance operations. Utilities, such as the galley and mess, food storageareas, change rooms and laundry, potable water and sewage treatment will be sized accordingly. Otherfacilities provided will include office, recreational, sick bay and entertainment amenities.The topside facilities will primarily be located on a horizontal plane raised above the vessel deck. It isenvisaged that the topsides will be configured in pre-assembled units, modules or pallets. The numberand size of units will be determined as design engineering is undertaken.Some of the topsides utilities required are: produced and oily water treatment; seawater filter andinjection systems; power generation; cooling and heating systems; fuel and inert gas systems; flare andvent system; drain systems; chemical injection; potable, service and fire water; nitrogen; diesel and jetfuel; compressed air; hydraulic power; de-icing; and safety and control systems.Personnel safety and environmental protection will be paramount in designing the facilities. This will applyto layout and construction and to the provision of safety systems, which will include:• emergency shutdown valves;• emergency flare and blowdown;• hazardous drain;• fire and gas detection;• active and passive fire protection;• personnel escape routes, temporary safe refuge and evacuation;• energy conservation; and• gaseous and liquid discharges.Communications are a critical component in the operation of an offshore oil facility, ensuring both thesafety of the facility and its competent operation. The FPSO, on-shore facilities, and all support craft willbe linked by state-of-the-art communications systems for voice, data or video.White Rose DA Project Summary • January 2001 Page 57
