Equipped with an SCR Diesel Electric propulsion system, the geophysical research vessel Western Strait has a cruising speed of about 13 knots. The 185-foot vessel was built by Mangone Shipbuilding for Western Geophysical Company. Mangone Delivers Research Vessel, Western Strait, To Western Geophysical The Western Strait, a highly sophisticated 185-foot geophysi- cal research vessel with an SCR Diesel Electric propulsion system, has been delivered to Western Geophysical Company by Man- gone Shipbuilding Company, a subsidiary of Stewart and Ste- venson Services, Inc. Constructed at the Mangone yard in Houston, Texas, the ship's first assignment is in South Amer- ican waters. Don L. Godeau, vice president and general manager of Mangone Shipbuilding, said the Western Strait joins a Western Geophysical fleet of some 30 ves- sels which are engaged in offshore research throughout the world. Built specifically for research and exploration, the Western Strait is 185 feet in length, has a 38-foot beam, a 16-foot depth and a 13-foot 8-inch draft. The ship has a range of 11,500 miles and a working capacity of 38 days. Cruising speed is approxi- mately 13 knots. Quarters are fully air-conditioned, with accom- modations for 39 geophysical per- sonnel and crew members. The SCR Diesel Electric pro- pulsion system supplies electric power with two 16V 149T1 De- troit Diesel engines each driving a 1,100-kw Kato a-c generator, providing power through SCR equipment to two Westinghouse 1,000-hp d-c motors with a Cotta marine gear on each shaft. Auxiliary generators aboard the Western Strait include one 250-kw set powered by a 12V71 Detroit Diesel and one 150-kw unit powered by an 8V71 Detroit Diesel. A 48-inch Murray and Tre- gurtha Harbor Master BT-375 bowthruster is driven by a 1,000- hp Westinghouse d-c electric motor. The SCR propulsion system controls developed by Interna- tional Switchboard Company are operated from a pilothouse con- trol panel. The ship's electronics include a Decca autopilot, Sperry gyrocom- pass, Raytheon DE-731 recording Fathometer, Leigh Class A E.P.- I.R.B., two Decca 65121 radar units, intercom system, and VHF and SSB radios. She is also equipped with Azimuth stabil- izers and a COMSAT 3941 sat- ellite communications system with telephone and telex. Geophysical research equipment aboard the Western Strait in- cludes an LRS-888 Seis Recording System with 100 channels; a com- plete satellite navigation system consisting of Hewlett-Packard Mini-computer, Doppler, Loran C, and satellite receiver; and nine TV monitors. Other equipment includes a LaCoste and Romberg Gravity meter, Geometries mag- netometer, Krupp fathometer, LRS-100 synchronizers, 20 air guns, six 5,000-psi electric-drive compressors, eight remote control "birds" for stabilizing- cable at a certain depth, and a 48 group cable. The vessel is also equipped with flume stabilization system, Halon firefighting system, Pitman #757 five-ton crane, a welding machine and a motor-generator set for clean power to the geophysical equipment. Chevron Orders Two 35,000-DWT Product Tankers From Mitsubishi Two new, diesel-powered, 35,- 000-deadweight-ton product tank- ers have been ordered by Chevron Transport Corporation, San Fran- cisco, Calif., a subsidiary of Stand- ard Oil Company of California, for service in the company's in- ternational trades. The vessels, which will be built by Mitsubishi Heavy Industries in its yard at Kobe, Japan, are scheduled for delivery in September and De- cember 1981. These product carriers will meet the safety and environmental re- quirements of the U.S. Port and Tanker Safety Act of 1978, as well as those of various conven- tions which have been adopted by the Inter-Governmental Maritime Consultative Organizations (IM- CO), the maritime agency of the United Nations. They will be equipped with protectively lo- cated segregated ballast tanks and inert gas systems. The addition of this new ton- nage to the company's fleet will serve to replace older product tankers in this size range which the company has scrapped over the last five years. A.L.
