The terminal consists of eight caverns with a total capacity of 50 million barrels (7,900,000 m3), a pump station with four 6,000-hp pumps, meters to measure the crude oil receipts and deliveries, and a 25-million-barrel (4,000,000 m3) Brine Storage Reservoir. The Clovelly Dome Storage Terminal is used to store crude oil in underground salt domes before it is shipped to the various refineries. 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. 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. 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. The pumping platform contains four 7,000-hp (5 MW) pumps, power generators, metering and laboratory facilities. The control platform is equipped with a helicopter pad, living quarters, control room, vessel traffic control station, offices and life support equipment. The Marine Terminal consists of a control platform and a pumping platform. The crude oil then moves to the Marine Terminal via a 56-inch (1.4 m) diameter submarine pipeline. The SPMs are designed to handle ships up to 700,000 deadweight tons (635,000 metric tonnes). Three SPMs are located 8,000 feet (2.4 km) from the Marine Terminal. Tankers offload at LOOP by pumping crude oil through hoses connected to a Single Point Mooring (SPM) base. 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. Most tankers offloading at LOOP are too large for U.S. LOOP provides tanker offloading and temporary storage services for crude oil transported on some of the largest tankers in the world. 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.
