During the next decade it is estimated that there will be a demand for about 80 liquid natural gas tankers, each with a capacity about 120,000 cubic meters. Because high reliability is required of these ships the equipment used must be both sophisticated and dependable. The propulsion system is the most important part of this system since delays can be very serious. In responding to the challenge of building a reliable propulsion plant burning both oil and LNG boil-off Hamworthy Engineering, Ltd., of Poole, Dorset, England, is ready to market an oil burning register which incorporates a gas burning facility and which permits operation in either the 100 percent oil or 100 percent gas modes or in any percentage mixture of the two fuels. A demonstration was held recently on a test rig consisting of a simulated marine boiler down-fired furnace with full instrumentation to show results. The rig incorporates an 8-ton capacity spherical tank for gas storage, which is useful for utilization of LNG boil-off. The conclusion of the article is that these dual fuel registers will become standard equipment in many future LNG ships.
