marine gas turbine
The gas turbineAir Compressor -The air is supplied by an air pretreatment unit comprising of a silencer, an air filter, and an air cooler. Reportedly built for HH the Aga Khan, this 42m yacht was powered by no fewer than six gas turbines coupled in pairs to three water jets. The first sections provide a look at the components that make up the gas turbine. Many modern four-stroke medium speed diesel engines have a maximum operating speed of around 500 rpm. High speed: any engine with a maximum operating speed above 1000 rpm. Benefits of dual-fuel engines include fuel and operational flexibility, high efficiency, low emissions, and operational cost advantages. steam plant. jets. With all this attention in the fast ferry world, the gas turbine has been Some smaller vessels may use high speed diesel engines. Since the late 1980s, Swedish shipbuilder Kockums has built a number of successful Stirling engine powered submarines. The natural gas is stored in a liquid state in cryogenic vessels aboard these ships, and a small amount of "boil-off" gas is needed to be constantly withdrawn in order to maintain the pressure and temperature inside the vessels within operating limits. In large aircraft carriers, the space formerly used for ship's bunkerage is used instead to bunker aviation fuel. cost have made it an unattractive option for ship owners. We specialize in the packaging of gas turbine engines for unique industrial applications. In recent times, there is some renewed interest in commercial nuclear shipping. common on the fast ferries and private yachts. turbine is an attractive alternative to diesels, and with the weigh/space However, the possibility of using gas turbines to power a superyacht’s other electrical systems is now being explored. oil for lubrication of parts. New liquefied natural gas (LNG) carriers continue to be built with steam turbines. The gas turbine can be used in combination with a steam turbine—in a combined-cycle power plant—to create power extremely efficiently. Vessels providing services in the LNG industry have been retrofitted with dual-fuel engines, and have been proved to be extremely effective.
