A new offshore crewboat, eighth in a series built for the same owner, has been delivered by Halter Marine Services, Inc., Chalmette (La.) Division, to Gray Mackenzie and Company, Ltd., Bahrain.
The new vessel is the Grayflier, a 78-foot crewboat whose home port will be Dubai. It was built to Lloyd's 100-A Arabian Gulf Service classification.
Grayflier can carry 40 passengers and its six-man crew is accommodated in a two-man officer's cabin and a four-man crew's quarters.
There is a full galley with mess for six. The vessel, for shipping to the Arabian Gulf, was fitted with a custom-built shipping cradle and loaded on deck of a freighter bound for Dubai.
The crewboat is powered by two General Motors 12V71 TI diesel engines that develop 510 bhp each. Controls are Morse manual at two stations, one in the wheelhouse and one aft. The vessel has a fuel oil capacity of 1,000 U.S. gallons. Reverse/reduction gearing is Twin Disc 2.0:1 and steering gear is Halter Hydraulic.
The crewboat is equipped with an emergency diesel-driven iy2-inch pump connected to two fire stations for fire protection, two Westinghouse air compressors, a Fairbanks Morse sanitary water system, four tons of Carrier heating and air-conditioning, and two 20-kw generators. Deck machinery includes a Skipper Hydraulic orbitrol-driven anchor windlass; communications equipment includes a Decca 48-mile range radar, an Intech VHF radio and a Ross fathometer.
Halter Marine Services' main shipyard is in New Orleans, La. The company owns and operates five other fully equipped shipyards in Louisiana and Mississippi, and is the world's largest builder of support vessels for the offshore oil and gas industry. These include crewboats, anchor-handling, rigtowing and supply ships, ocean tugs and vessels for the inland waterway industry.
