Louisiana Offshore Oil Port
The Louisiana Offshore Oil Port (LOOP) is a deepwater port in the Gulf of Mexico off the coast of Louisiana near the town of Port Fourchon. LOOP provides tanker offloading and temporary storage services for crude oil transported on some of the largest tankers in the world. Most tankers offloading at LOOP are too large for U.S. inland ports. LOOP handles 13 percent of the nation's foreign oil, about 1.2 million barrels (190,000 m3) a day, and connects by pipeline to 50 percent of the U.S. refining capability.
Tankers offload at LOOP by pumping crude oil through hoses connected to a Single Point Mooring (SPM) base. Three SPMs are located 8,000 feet (2.4 km) from the Marine Terminal. The SPMs are designed to handle ships up to 700,000 deadweight tons (635,000 metric tonnes). The crude oil then moves to the Marine Terminal via a 56-inch (1.4 m) diameter submarine pipeline. The Marine Terminal consists of a control platform and a pumping platform.
The control platform is equipped with a helicopter pad, living quarters, control room, vessel traffic control station, offices and life support equipment. The pumping platform contains four 7,000-hp (5 MW) pumps, power generators, metering and laboratory facilities. Crude oil is only handled on the pumping platform where it is measured, sampled, and boosted to shore via a 48-inch (1.2 m) diameter pipeline.
LOOP's onshore facilities, Fourchon Booster Station and Clovelly Dome Storage Terminal, are located just on-shore in Fourchon and 25 miles (40.2 km) inland near Galliano, Louisiana. The Fourchon Booster Station has four 6,000-hp (4.5 MW) pumps which increase the pressure and crude oil flow en route to the Clovelly Dome Storage Terminal.
