MT30 Marine gas turbineTHE WORLD’S MOST POWERFUL IN-SERVICE MARINE GAS TURBINE

Designed for the 21st century

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

The power and performance of this modern gas turbine is providing shipbuilders and system designers with new options, choices and the ability to futureproof their latest naval platforms.

KEY FEATURESModern, state-of-the-art gas turbine technology delivering…

• 36MW or 40MW flat rated to 38°C.

• No power loss between overhauls.

• Ultra-low maintenance requirements.

• Turbine operates at 70°C below design limits enabling World-leading times between overhaul.

• Member of the aero Trent family, with more than 50 million service hours, providing excellent reliability and optimised spares availability.

• Approximately 40% thermal efficiency.

• Modular design for simplified engine maintenance. Self-contained, single lift package.

• Low emission levels.

• 100% power retention, maximum power and efficient fuel consumption throughout life

• Condition based monitoring system using embedded Engine Health Management

• High-pressure ratio gas generator with free power turbine

• Low vibration unit, resiliently mounted

• Fully Integrated Control System

OPERATIONAL FLEXIBILITY• Electric or hydraulic start providing improved operational flexibility with immediate

re-starting capability.

• After normal or emergency shutdowns, the engine can be restarted at any time with no rotor lockout.

• The free power turbine allows a wide range of matching of output speed to spool speed. This allows the MT30 to operate a range of cube law power curves and output through a wide range of drive configurations.

• Excellent speed control characteristics and frequency recovery for sudden load changes in generator applications.
