THOROUGHBRED TOPPER Bay Shipbuilding Bay Shipbuilding Corporation of Sturgeon Bay, Wise., a subsidiary of The Manitowoc Company, recently delivered the oceangoing coal top- off barge Thoroughbred Topper to Lamberts Point Barge Company, a subsidiary of the Norfolk Southern Corporation of Norfolk, Va. The big 33,000-dwt vessel will be operated by Coastal Barge Corporation, a subsidiary of the Dowd Group of New York. The Topper will be used primari- ly for topping off partially loaded, oceangoing bulk coal carriers of such size that they have too deep a draft to be completly loaded at U.S. coal-loading terminals. This proce- dure will allow vessels that receive a partial load of cargo at the coal docks to proceed to deeper water, where they will be topped off to full cargo capacity. The barge has an overall length of 550 feet, beam of 78 feet, and draft of 34 feet; capacity is in excess of 36,000 short tons of coal. She is fit- ted with a deep stern notch to accommodate a 7,200-bhp tug. The December 1, 1984 barge is equipped with hydraulically controlled skegs to maintain direc- tional stability while under tow. A 1,000-hp, fixed-pitch bow thruster provides additional maneuverabili- ty. Bay Ship's parent, The Mainito- woc Company, provided two 4600 Series-3 clamshell cranes that pro- vide the barge with self-loading, un- loading, and transfer capabilities in excess of 1,500 tons per hour. The two 4600s rotate on special 16-foot roller paths mounted atop self-pro- pelled gantries that travel on rails along the length of the four cargo holds. The gantries, manufactured by Bay, also serve as hatch cover cranes. Each crane is equipped with a 120-foot boom and provides 50,000-pound clamshell capacity. In addition, each is equipped with an operator's module to provide op- timum visibility for loading. The Thoroughbred Topper com- plies with all regulations of the U.S. Coast Guard, and is classed by the American Bureau of Shipping +A1 Barge, Unrestricted Ocean Service, (continued on page 38) THOROUGHBRED TOPPER Major Suppliers Clamshell cranes . . . .Manitowoc Engineering Crane gantries ....
