The Rolls-Royce Marine Spey is a marine gas turbine based on the Rolls-Royce Spey and TF41 aircraft turbofan engines. [1] The Marine Spey currently powers seven ship classes including the Royal Navy's Type 23 frigates and provides a power output of 19.5 MW (about 26,150HP). The Marine Spey incorporates technology from the Tay and RB211.
The Rolls-Royce MT30 (Marine Turbine) is a marine gas turbine engine based on the Rolls-Royce Trent 800 aero engine. The MT30 retains 80% commonality with the Trent 800, the engine for the Boeing 777. The maximum power rating is 40 MW and minimum efficient power 25 MW. [1] Rolls-Royce announced the MT30 program on 11 September 2001.
The General Electric LM2500 is an industrial and marine gas turbine produced by GE Aviation.The LM2500 is a derivative of the General Electric CF6 aircraft engine.. As of 2004, the U.S. Navy and at least 29 other navies had used a total of more than one thousand LM2500/LM2500+ gas turbines to power warships. [1]
The LM1500 was derived from the J79 engine in 1960. [3] Its first application was for the first US sea-going research hydrofoil, HS Denison. [1] Conversion as a marinised turboshaft engine involved two major changes: the addition of a free power turbine, and corrosion-protection by the addition of internal coatings and a maintenance scheme of freshwater rinsing to prevent salt damage.
The General Electric LM1600 is an industrial and marine gas turbine produced by GE Aviation. The LM1600 is a derivative of the General Electric F404 aircraft engine series. [ 1 ] [ 2 ] The LM1600 delivers 20,000 shaft horsepower (shp) (14,920 kW) with a thermal efficiency of 37 percent at ISO conditions .
Some warships, and a few modern cruise ships have also used steam turbines to improve the efficiency of their gas turbines in a combined cycle, where waste heat from a gas turbine exhaust is utilized to boil water and create steam for driving a steam turbine. In such combined cycles, thermal efficiency can be the same or slightly greater than ...
The General Electric LM6000 is a turboshaft aeroderivative gas turbine engine. The LM6000 is derived from the CF6-80C2 aircraft turbofan.It has additions and modifications designed to make it more suitable for marine propulsion, industrial power generation, and marine power generation use.
The first Marine Olympus was built for the German Navy. In 1962 BSEL was contracted to provide the gas-generator and Brown Boveri was contracted to provide a two-stage long-life marine power turbine. A test bed was built for extensive shore trials. Construction of the ship which was intended for gas-turbine power was abandoned.
