Bath Iron Works-Portland drydock Shiplift/Drydock (continued) ing and pumping system of the pon- toon. The wing walls, which house more than 28,000 square feet of potential office and shop space, are 48-feet high, 18-feet wide, and 101-feet long. The distance between wing walls is 122 feet. In the assembled dock—with three-foot spaces between sec- tions—the wing walls of the individ- ual pontoons are connected with welded plates. This creates two con- tinuous box girders extending the full-length of the dock, while it also provides longitudinal moment strength. To be devoted primarily to the repair and inspection of mobile off- shore drilling units and production facilities, the drydock contains electrical generating equipment, utility capacity, and cranes, and is equipped with machine, carpenter, and electrical shops. The sectional dock can be config- ured to provide a clear docking area of either 413 by 362 feet or 829 by 122 feet, depending on the size and shape of the incoming vessel. This unique flexibility will accommodate jackup rigs, semisubmersibles, sub- mersibles, and drillships. The U.S. Navy surplus drydock, built during World War II, was transported earlier this year from Pearl Harbor to Bethlehem's Beau- mont Yard, where it was refur- bished and modified.
