Gas Turbine-Powered LNG Tanker Discussed At Turbine Conference New marine applications of the heavy duty gas turbine, including design features of the power plant for the world's first gas turbine LNG carrier, now under construc- tion, were discussed in a report recently released at the Interna- tional Gas Turbine Conference and Products Show in Washing- ton, D.C. The gas turbine and its associ- ated systems are inherently simple to operate, and have been shown to be readily adaptable to marine service, according to the report presented by N.A. Svensen of Gen- eral Electric Company's Gas Tur- bine International Department. "We have found gas 'turbine in- stallations eminently well suited for simple single-level no-man-watch automation. The ability to utilize virtually any fuels in almost any combination certainly will prove its economic merits," states Mr. Sven- sen in the report. Moss-Rosenberg Hull #177— the Hilmar Reksten vessel now un- der construction in Norway—is the world's first gas turbine LNG car- rier. The power plant for the ship is a GE MS 5002A gas turbine with dual fuel system which can operate on liquid and gas fuels simultane- ously. This gas turbine is a two- shaft regenerative machine design- ed to develop 20,000 shp for a CRP propeller operating at full load at 125 rpm. '"The power plant oc- cupies a rather small area," Mr. Svensen said. The tanker will carry 29,000 cubic meters of LNG in four spherical tanks. The report discussed in detail the tanker's dual fuel combustion sys- tem examined with respect to the use of LNG boil-off gas fuel, the liquid and gas fuel processing sys- tems, control system, and classifi- cation requirements. The Reksten vessel will be classed by Det norske Veritas for Class EO, periodically unmanned engine room. In addition, the pow- er plant is designed to meet U.S. Coast Guard LNG boil-off fuel reg- ulations. For these and many, oth- er reasons discussed in the report,, which was given at the large meet- ing of international gas turbine specialists convened in Washing- ton, the "keel-laying" of this ves- sel "represents a fairly significant event to the shipbuilding and ship- ping industries." Pactow Buys 5 Tugs —Opens Ship Docking Office In San Diego Pacific Towboat & Salvage Co., a subsidiary of Dillingham Corpor- ation (NYSE}, has announced that it has acquired the five tug3 and two barges of Star & Crescent In- vestment Co. and will now provide ship-docking service in San Diego Harbor under the Pactow name. The purchase became effective April 2, 1973. J.J. Turner, president of Pactow, said his firm had established a new division with offices in San Diego. Gary Coslett has been named Pac- tow manager in San Diego. He was formerly at the company's head- quarters in Long Beach. Pacific Towboat & Salvage Co. was founded in Long Beach in 1928 and now has one of the largest fleet of tugs and barges in southern Cali- fornia. It became a wholly owned subsidiary of Dillingham Corpora- tion in 1970. Dillingham Corporation is head- quartered in Honolulu. Its mari- time, construction, property de- velopment, and resource activities are concentrated in the Pacific Basin. RPC Division Midland-Ross Corp. Appoints Deane Adams Deane L. Adams has been named product manager for Tami-Lift mobile straddle cranes manufactur- ed by the RPC Division of Mid- land-Ross Corporation for marine and industrial use. Mr. Adams joined the company a year ago as sales manager for Tami-Lift cranes and allied equip- ment. He is headquartered at the RPC Division in Roxboro, N.C. aren't you a • v It seems such a simple question: what happens to that last bit from a tank or tanker? Yes, but what is actually purged and where is it left . . . just think about it and ask yourself how it would be if you used a different pumping technique. A screwpump for example. A screwpump which also removes that very last bit. (The bit that often has economical value too!) Does a screwpump meet your technical requirements? Have a look at the brief data below and you'll know the answer.
