Campbell Industries Completes Specialized Vessel Designed To Tow Oil Drilling Rigs i The Independence Service, built by Campbell Industries, San Diego, Calif., was recently delivered to Zapata Marine (U.S.), Inc., a Zapata Corporation subsidiary. The 208-foot ship will go into service initially in the Gulf of Alaska. Campbell Industries, San Diego, Calif., has delivered its second tug/supply vessel, the Independ- ence Service, for Zapata Marine (U.S.), Inc., a subsidiary of Za- pata Corporation, Houston, Tex- as. The new U.S.-flag ship is the second of six being built for Za- pata. Campbell previously deliv- ered her sistership, the Constitu- tion Service. The newest vessel is scheduled to go into service initially in the Gulf of Alaska. The 208-foot Independence Service is 40 feet wide at the beam, has a draft of 14.5 feet, and will cruise at approximately 15 knots. The specialized vessel is designed to tow drilling rigs, as well as to relocate the plat- forms' positioning anchors, which weigh up to 20 tons apiece. In addition to an operating crew of 8 to 12, the ship can also carry crews being transferred to and from the platforms, and all nec- essary supplies. A reduced man- ning level has been achieved through installation of additional controls and a Smith-Meeker monitoring/alarm system. Key payload items are bulk cement and the drilling "mud" used by the oil operators. The "mud" is a substance carried in dry form which is used to seal off well shafts and circulates to clean and cool the drilling bits. According to Campbell officials, the new ship is fully Coast Guard inspected and is rated ABS Ice Class IC, Maltese Cross, with Circle E equipment. Certified for full ocean towing, the Independ- ence Service will carry a full complement of equipment for its duties in the offshore drilling in- dustry. She will have a mud sys- tem made up of four Smatco 1,500-cubic-foot-capacity tanks, each 13 feet 6 inches in diameter, and 13 feet 8 inches high. In- cluded in the system is a West- inghouse air compressor, driven off a General Motors 6/71 diesel engine. The ship's towing winch is a Smatco 72-DAW-250 double- drum waterfall, rated at 300,000 pounds at stall. It is driven by a GM 12V71 diesel on the main deck aft of the deckhouse. The stern roller, manufactured by Campbell Industries, is a 12-foot 60-inch-diameter model with a safe working load of 150 tons. The two stern capstans are ver- tical-axis Smatco versions, with electrohydraulic drive. Propulsion for the Independ- ence Service comes from two Gen- eral Motors 16-cylinder 645E5 turbocharged diesels, each rated at 2,875 bhp at 900 rpm. They drive a pair of 132-inch Coolidge four blade stainless-steel propel- lers through Falk 4.35:1 reduc- tion and reversing gears. The propellers are set inside fixed nozzles with individual rudders. Auxiliary power is provided by two GM 12V71 diesel drive units with 220-kw Lima generators. Ship's service air comes from two Quincy D340 compressors. The Independence Service has a bollard pull rating of 80-90 tons. The vessel also features a Mc- Mullen Flume stabilization sys- tem and a Brunvoll 51-inch-di- ameter bow thruster. The 405- horsepower thruster is rated at 10,000 pounds thrust and is driven by a GM 12V71 diesel unit. Navaids and other electronic equipment onboard include a Sperry gyrocompass and auto- pilot, two Decca radars, a Kelvin- Hughes Loran system, a Ray- theon recording Fathometer, a Bendix Marine ADF, a CAI SSB radio, an Intech 55-channel VHF- FM radio, a Hallicrafters emer- gency receiver, and a Standard PA/Intercom system. Water-ln-Fuel Oil Homogenizers Described In Gaulin Brochure A new eight-page technical bro- chure, available from Gaulin Cor- poration, explains the role of water-in-fuel oil emulsification for improving the performance and operating economy of both sta- tionary and marine boilers and gas turbines. The brochure is illustrated with microphotographs of water-in- fuel oil emulsions and compara- tive combustion sequences, and describes a number of successful steam boiler and gas turbine ap- plications.

Names Frank Hsu Frank Hsu has been named sales manager of Evergreen Handt Corp., One World Trade Center, Suite 1627, New York, N.Y. 10048, general agents for Evergreen Lines East Coast/Far East Container Service. The announcement was made by Svend Hansen Jr., president of Evergreen Handt. Mr. Hsu has been with the Evergreen Marine Corp. for 7 years. In 1974, he came to the United States and helped plan the introduction of this service. Mr. Hsu studied oceanography at the College of Chinese Culture, Taipei, Taiwan, and served as a second lieutenant in the transpor- tation division of the Chinese Army. Evergreen operates a fleet of new, specially built container ves- sels in a regular service to the ports of Pusan, Korea; Keelung and Kaohsiung, Taiwan; and Hong Kong. Hitachi Zosen Receives Floating Pontoon Jetty Contract From Arabia i u Yasuhiko Kosa Yasuhiko Kosa, director and general manager of the Hitachi Zosen Offshore Plant Division, has announced the receipt of an order from the Ministry of Pub- lic Works and Housing of the Kingdom of Saudi Arabia to con- struct three floating pontoon jet- ties. Installation will begin in the autumn of this year. Each jetty comprises three pontoons measuring 197 feet in length by 131 feet in width, which are joined end-to-end by hinges and connected to an abut- ment by a link system. Two jet- ties will be installed near Thuwal on the Red Sea, and the third near Ras A1 Ghar on the Arabian Gulf. Each can accommodate ships up to 20,000 dwt. While these jetties will be used primarily to moor ships bringing housing construction materials to Saudi Arabia as part of the Ministry's housing construction program, they will also contrib- ute to alleviating port congestion in the country. According to Mr. Kosa, this order is the first Hitachi Zosen has received independently from the Kingdom of Saudi Arabia, and the first by the Offshore Plant Division since its establish- ment in September 1976 to allow the company to become more ac- tive in the supply of offshore plants, machinery and steel struc- tures. SNAME West Gulf Section Meets In Houston, Texas The West Gulf Section of The Society of Naval Architects and Marine Engineers held its final meeting of the 1976-77 season in the Houston (Texas) Engineer- ing and Scientific Society Build- ing. John C. Chivvis Jr., vice chairman, presided during the technical dinner meeting. Following the social hour and dinner, Peter Fisher, naval archi- tect,, Matson Navigation Com- pany, San Francisco, Calif., pre- sented a paper entitled "The Effects of Variation of Hull Geo- metric Parameters on Towed Ocean-Going Barges." David C. Kilgore of The Off- shore Company arranged for the meeting, and Anil Raj of Brown & Root, Inc., arranged for this interesting paper. A unique ship "delivery" took place when Campbell Industries presented this hand- crafted model of the tug/supply vessel Constitution Service to Zapata Corporation of Houston, Texas. Campbell president Paul I. Stevens (left) and Zapata construc- tion representative Ed Parker (center) hold the all-wood model as its builder, Joe Silva, explains some of the ship's finer details. Mr. Silva, who is Campbell's hull design and construction supervisor, has previously built models of the company's famous tuna seiners, one of which is on permanent display at the Smithsonian Institution in Washington, D.C.
