MT30 Marine Gas Turbine

World's most powerful in-service marine gas turbine

The MT30 integrates world leading marine gas turbine technology to give operators efficiency and reliability in a compact package with a market-leading power-to-weight ratio

MT30 Marine Gas Turbine

Designed with approximately 50 per cent fewer parts than other aero-derived gas turbines in its class, to minimise maintenance costs, the MT30 has a twin-spool, high-pressure ratio gas generator with free power turbine. It maintains operating efficiency down to 25MW and can be configured in either mechanical, electrical or hybrid drive configurations. Proven at sea, MT30 entered service in 2008 powering the US Navy's first of class Littoral Combat Ship, USS Freedom.

MT30 is the most power dense naval gas turbine available today, proven to deliver superior performance, operational flexibility and reliability. This is why it is already the engine of choice for world’s most advanced naval platforms including the Royal Navy’s Queen Elizabeth-class aircraft carriers and Type 26 Global Combat Ship and variants, the US Navy’s Littoral Combat Ship Freedom-class variant and DDG-1000 advanced destroyer, Republic of Korea Navy’s Daegu-class and Ulsan-class frigates, the Italian Navy’s Landing Helicopter Dock, Trieste, and the Japanese Maritime Self Defence Force’s Mogami-class 30FFM frigates.

Rolls-Royce combines innovative naval technology with a proven high performing naval pedigree to deliver the most cost effective and efficient ship power, propulsion and through-life solutions for customers around the world.

Fully Integrated Control System

The MT30 control system provides fully integrated alarm, monitoring and control functions for the packaged gas turbine, including overspeed protection. An integral back-up power supply is an option. A distributed processing architecture uses modern databus technology to provide improved reliability through simplified wiring and a reduced number of connectors, with main processors and power supplies located on the outside of the package enclosure.

The system supports Fully Integrated Control System unmanned operation by making engine control and monitoring available over dual redundant databus and hard-wired signals for full integration into the platform control system. It can also be set to log predetermined engine/package data for optional off-board engine health monitoring and logistical support.

A local control panel is provided to display all necessary engine and package parameters and enabling control of engine functions, maintenance and calibration activities.
