In April or May a specially trained mooring master will board a supertanker 24 miles off Lafourche Parish Louisiana, to begin the first offloading test from a US offshore terminal. The vessel will be guided shoreward for 5 miles and positioned at one of three SALM (Single Anchor Leg Mooring) buoys. The tanker will be moored only by bowlines, permitting it to weathervane into prevaling wind and waves while it offloads into the LOOP (Louisiana Offshore Oil Port) terminal. The $630,000,000 facility is constructed in 110-ft water in Grand Isle Block 59, approximately 19 miles offshore. The terminal is the first serious US effort to build a facility capable of handling supertankers and gain the economics of scale the large-volume ships offer. The components of LOOP are discussed and the mooring systems are explained. LOOP will handle six different designations of crude imports; use of the specific caverns for segregation is important. The Clovelly facility is an underground tank farm. Crude will move in and out of the caverns via brine displacement. Crude pumped into a cavity will displace brine to the surface storage reservoir. Typically, oil leaving the Clovelly Salt Dome will head northwest through the 48 inch diameter LOCAP pipe line connecting the dome with the St. James terminal of Capline. From St. James, the crude either will be piped to refineries in Louisiana or sent up the Capline system. Because of Capline and adjacent crude pipe lines, LOOP imports are connected with approximately 25% of the nation's refinery capacity. (DP)
