Map Awards Delayed Coker Job To Bechtel Project To Build World´s Largest Two-drum Coker In Louisiana

November 16, 1999 Marathon Ashland Petroleum LLC (MAP) has awarded Bechtel Corporation a lump-sum contract for the technology license, design, and construction of a 34,500-barrel-per-day delayed coker at its Garyville refinery in Louisiana. MAP is owned 62 percent by Marathon Oil Company and 38 percent by Ashland Inc.The MAP delayed coker will be the world's largest two-drum coker, with 30-foot-diameter coke drums. Construction is scheduled to be completed in September of 2001.

The delayed coker will use Conoco-Bechtel Delayed Coking Technology to process heavy feedstocks. Conoco's patented distillate recycle technology will be used to increase the yields of more valuable lighter products and to improve furnace run lengths between heater decoking operations.

The MAP delayed coker is the most recent award to Bechtel resulting from the current heavy-oil upgrading capacity increase in the North American refining market. In addition to Garyville, Bechtel is designing and constructing delayed cokers for Merey Sweeny L.P. (a joint venture of PDVSA and Phillips Petroleum Company) at the Sweeny refinery in Texas, the Exxon Baytown refinery in Texas, HOVENSA (a joint venture of PDVSA and Amerada Hess Corp.) at its refinery in St. Croix, U.S. Virgin Islands, and (with Bantrel) the Suncor Energy oil sands upgrading facility in Fort McMurray, Alberta.

Based in Findlay, Ohio, MAP (www.mapllc.com) is the nation's fourth largest refiner with 935,000 barrels per day of capacity in its seven-refinery system. MAP's retail marketing system comprises approximately 5,400 locations in 21 states, more than half of which are brand locations. Marathon Oil Company is part of the USX-Marathon Group (NYSE:MRO), a unit of USX Corporation.

Bechtel, headquartered in San Francisco, is one of the world's leading engineering, construction, and development companies. The firm has worked on some 20,000 projects in 140 countries on all seven continents over the past century.
