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 WR-21 is the first aeroderivative gas turbine to incorporate gas compressor intercooler and exhaust heat recovery system technologies that deliver low specific fuel consumption across the engine's operating range. [3] It offers a reduction in fuel burn of 30% across the typical ship operating profile. [5]
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.
Dual fuel engines are fueled by either marine grade diesel, heavy fuel oil, or liquefied natural gas (LNG). A Marine LNG Engine has multiple fuel options, allowing vessels to transit without relying on one type of fuel. Studies show that LNG is the most efficient of fuels, although limited access to LNG fueling stations limits the production of ...
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 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.
If the turbines do not drive a propeller shaft directly and instead a turbo-electric transmission is used, the system is known as COGES (combined gas turbine-electric and steam). COGAS differs from many other combined marine propulsion systems in that it is not intended to operate on one system alone.
The marine version, the Rolls-Royce Tyne RM1A, RM1C and RM3C remained in service as the cruise gas turbines in Royal Navy Type 21 frigates, Type 42 destroyers and Type 22 frigates until the retirement of the 4 Batch 3 Type 22 frigates (2011) and the last remaining Type 42 Destroyer (2013).
