Harbor Supply Vessel Completed By Delaware Marine A recent delivery from the ship- building yard of Delaware Marine & Manufacturing Company was the harbor supply vessel Will- kate, which was built for Marine Launch Company, Inc. of Balti- more. The all-welded steel vessel has been placed in service in Bal- timore's Inner Harbor where it is being used to carry provisions and lube oil, in sealed containers, to ships using the port. The Willkate has an overall length of 64 feet 11 inches, a beam of 18 feet 6 inches, and a loaded draft of 6 feet 4 inches. The vessel is certificated by the U.S. Coast Guard to carry 28 con- tainers of lube oil containing 500 gallons each. All cargo is carried on the vessel's flat afterdeck. The husky workboat is powered by a 270-bhp Cummins model NT- 855-M marine diesel, which drives a 42-inch-diameter, 28-inch-pitch three-blade propeller through a 3:1 reduction gear and 2%-inch- diameter stainless steel propeller shaft. Service speed is about 12 knots. The main cargo pump is a 200-gpm Viking driven by a four- cylinder Chrysler diesel engine.

Ray E. Pierce, Section chairman, Philadelphia Naval Shipyard; George B. Manning, author, U.S. Department of Energy; and Eugene P. Weinert, Section vice chairman, Naval Ship Systems Engineering Station, Philadelphia. The American Society of Naval Engineers, Delaware Valley Chap- ter, Philadelphia, Pa., held a re- cent meeting at the Officer's Club, U.S. Naval Base, Philadelphia. Following a social hour and din- ner, Chapter chairman Capt. Ray Pierce formally opened the meet- ing and turned over the technical session to meeting coordinator John Siemietkowski, Naval Ship Systems Engineering Station, Philadelphia, who introduced George Manning, Department of Energy, Washington, D.C., pre- senter and author of the evening's paper titled "Multiple Fuel Capac- ity for Large Gas Turbines." The author reviewed the gas turbine fuel system, which pres- ently burns liquid fuel. However, it was noted that there is a great amount of interest in gas tur- bines which would use a coal- derived fuel. The paper described a most interesting current re- search and development program on the largest coal-burning gas turbines being developed by the Department of Energy. A lively question and answer and discus- sion period concluded the techni- cal presentation. Captain Pierce presented George Manning with a Certificate of Ap- preciation for a timely and out- standing presentation.
