Mangone Delivers Advanced Offshore Research Vessel
Mangone Shipbuilding Company recently delivered the Western Narrows, an ultramodern, geophysical research and survey vessel with SCR (silicon-controlled r e c t i f i e r ) diesel-electric propulsion, to Western Geophysical Company of Houston. Mangone, a subsidiary of Stewart & Stevenson Services, Inc., delivered a sister ship to the same owner last fall.
These two vessels are the newest additions to the Western Geophysical fleet of some 30 ships doing offshore research around the world, according to Mangone vice president and general manager Don Godeau.
The Western Narrows is 185 feet long with a beam of 38 feet, depth of 16 feet, and draft of 13 feet 8 inches (55.5 by 11.4 by 4.8 by 4.1 meters). Range is approximately 13,800 miles, working ca- pacity 52 days, and cruising speed about 11 knots. Accommodations for 40 crew and geophysical personnel are fully air-conditioned.
The SRC diesel-electric propulsion system is said to give the ship greatly improved fuel economy and precision control. Two 16V 149T1 Detroit Diesel Allison engines each drive 1,100-kw Kato ac generators that supply power through the SRC equipment to two Westinghouse 1,000-hp dc motors, with a Cotta marine gear on each shaft. SRC system controls by International Switchboard Company are in the pilothouse and engine room.
The Western Narrows also has a 250-kw auxiliary generator powered by a 12V71 Detroit Diesel engine, and a 150-kw unit powered by a Detroit Diesel 8V71 engine.
The ship has a 48-inch Murray & Tregurtha Harbor Master RT-375 bow thruster driven by a Westinghouse 1,000-hp dc motor.
Electronic equipment includes Decca autopilot, Sperry gyrocompass, Raytheon DE-731 recording Fathometer, two Decca 65121 radars, intercom system, and VHF and SSB radios. She also has azimuth stabilizers and a Comsat General 3941 satellite communications system with telephone and telex.
Also aboard the Western Narrows is a FLUME stabilization system, halon firefighting system, Pitman #757 five-ton crane, welding machine, and a motor-generator set for power to the geophysical equipment.
The vessel is classed by the American Bureau of Shipping and c e r t i f i c a t e d by the U.S. Coast Guard.
