January, 1925 MARINE REVIE W 15 On the J.W.Van Dyke ESTINGHOUSE electrical equipment has been selected by the Atlantic Refining Company for the conversion to Diesel-Electric drive of the 8000 ton tanker, J. W. Van Dyke, formerly the United States Shipping Board Ship, Allentown. This is the largest ship, in point of dead weight tonnage, yet under contract for conversion to Diesel-Electric drive. Power for propulsion and auxiliaries will be supplied by three 600 kw. Diesel-driven Westinghouse gener- ators with 50 kw. exciters. The single propelling motor is to be a 2300 shp., double armature West- inghouse motor, controlled directly from the pilot house by the Ward-Leonard system. In port, one of the main generator sets is switched from the propelling circuit to the pump circuit, and supplies the pump motors, which handle the 60,000 barrels of oil. This illustrates the flexibility and economy of the Diesel-Electric System. For conversion or construction, Westinghouse en- gineers will gladly cooperate with you to lay out the most efficient electrical equipment for your ship.
