Halter Marine Building Offshore Oil-Well Boat Sedco, Inc., (Southeastern Drilling, Inc.), of Dallas, Texas, has placed an order with Halter Marine Fabricators, Inc., Moss Point, Miss., for the construction of an offshore oil-well supply boat. Designated Hull No. 227, and to be powered with 1,700-total-bhp diesels, the vessel will have the following dimensions: 166 feet by 40 feet by 15 feet. Manning Electric Appointed Distributors By Edison Ind. For Voltage Control Equipment Donald Manning, president of Manning Electric Inc., 52 Warren Street, New York, N.Y. 10007, has announced the appointment of his firm as marine distributors for the Thomas A. Edison Industries for general sys-tems voltage control equipment. General Systems manufactures voltage regu-lators, current limit controls, and reverse cur-rent rectifiers for the marine trade. Edo Western Introduces Doppler Current Meter Edo Western Corporation, Salt Lake City, Utah, has announced the development of a completely new concept for the measurement of flowing currents. The Model 429 Doppler Current Meter is designed to meet the in-creasing need for valid, precise measurement of flowing currents ranging from 0-0.5 feet/ second to 0-15 feet/second in water depths to 500 feet. This new measuring system consists of an underwater section and a surface unit which contains instrument readout and controls, and operates on the principle of volume reverbera-tion and reflection signal frequency shift. This method provides high accuracy at very low current rates and allows fast current accelera-tion measurement. The underwater package is faired to minimize flow disturbance, and to act as a vane to keep the meter pointed in the direction of current flow. It is connected to the surface package by an underwater inter-connecting cable. Error-causing current dis-turbances are minimized by measuring the current flow at an acoustical beam intersection, approximately one foot in front of the trans-ducers. Transmitting and receiving trans-ducers are mounted at an angle of 20 degrees with respect to the face of the meter. Very small particles of water reflect energy and act as point energy sources for the beam pattern of the receiving transducer. The received sig-nal has a Doppler frequency shift expressed in a difference frequency for signal processing by the surface package. The Model 429 Doppler Current Meter is easily maintained and serviced because of its modular, all solid-state construction. Inter-changeable printed circuits are used through-out the system, facilitating ease in field troubleshooting and repair.

G. Willis, Inc., Paulsboro, N.J. The 221-foot by 35-foot by 12-foot vessels will be of 2,000-dwt. Dravo is also building ten covered hopper barges for stock purposes only. These barges will have dimensions of 195 feet by 35 feet by 12 feet. Gunderson Bros. Engineering Corp., Port-land, Ore., was awarded a contract by Crowley Launch & Tugboat Co., San Francisco, Calif, for the construction of two 4,500-dwt cargo barges. Designated Hull Nos. 16546?3 and 4, each will have dimensions of 250 feet by 76 feet by 18 feet 6 inches. Ingalls Iron Works Co., Birmingham, Ala., was awarded a contract by Canal Barge Co., Inc., New Orleans, La., to build an oil barge. The 3,000-dwt barge will have the following dimensions : length?250 feet; width?50 feet; depth?14 feet 6 inches. Jeffboat, Inc., Jeffersonville, Ind., was con-tracted by Ellis Towing & Transportation Co., Galveston, Texas for the construction of three 1,500-dwt tank barges. Each barge will have the following dimensions: 195 feet by 35 feet by 12 feet 6 inches. Levingston Shipbuilding Company, Orange, Texas, was awarded a contract for the con-struction of a marine pipe laying barge, by J. Ray McDermott & Co., Inc. The announce-ment was made by Roger W. Wilson, presi-dent of the company. To be named McDer-mott Lay Barge No. 23, it is designed to lay pipe in deepwater. The unit will be 420 feet long and 120 feet in width and will have two 100 ton gantry cranes and a constant tension-ing device to facilitate pipelaying. Zigler Shipyards, Inc., Jennings, La., will build an independent tank barge designed for the movement of chemicals, for Durow Corp., New Orleans, La. It has been designated Hull No. 195, and will be named D.C. 110. The 1,500-dwt barge will have the following dimensions: 193 feet 9 inches by 35 feet by 11 feet. Fairbanks-Morse Diesels To Propel Nine MSTS Tankers The largest order since World War II for diesel engines to propel commercial U.S.-flag ships has been placed with the Fairbanks-Morse Power Systems Division of Colt Indus-tries, Beloit, Wis. The order is reported to be valued at $12-million dollars. This diesel engine order results from the award of a build-and-charter contract by the Military Sea Transportation Service to Central Gulf Steamship Company for nine 25,000-dwt tankers. Central Gulf has ordered the tankers from Bethlehem Steel Corporation's Sparrows Point, Md., shipyard. The proposals received by MSTS for these tankers covered both steam and diesel propul-sion, with the selection of the type of power-plant left up to the Navy. Each ship will be propelled by two six-cylinder engines. The engines are rated at 1,250 hp per cylinder, thus giving a total output of 15,000 hp. The propeller shafts will drive attached electric generators. Carstone To Represent lulius Mock & Sons Carson Stone, president of Carstone Corpo-ration of 321 Carondelet Building, New Or-leans, La., has announced the firm's appoint-ment as Gulf area representative for Julius Mock & Sons, Inc. of Brooklyn, N.Y. The Mock organization specializes in Navy and commercial hinged closures such as doors, hatches and scuttles. 58 Maritime Reporter/Engineering News
