The MT30 Marine Gas Turbine Powering the world’s future fleets

 Open the catalog to page 1

Powering the world’s future fleets Designed for the 21st century The MT30 encompasses the very latest in marine gas turbine technology and gives operators of gas-turbine powered vessels efficiency and reliability improvements, with a market leading power-to-weight ratio and reduced operating and throughlife costs. Designed with 50 to 60 per cent fewer parts than other aero-derivative gas turbines in its class, the MT30 has been granted type approval from ABS and Lloyds Register and is DNV design assessed. It maintains operating efficiency down to 25MW. The MT30 can be configured for either...

MT30 - Powering the world’s future fleets Advanced design – proven technology The compact and lightweight MT30 is a twin-spool, high-pressure ratio gas generator with a free power turbine, an eight stage variable geometry intermediate pressure compressor and a six-stage corrosion protected high pressure compressor. Three stages of variable vanes and blow off valves are provided for compressor handling purposes and a continuous flow of IP delivery air is taken for bearing sealing and cooling purposes. The four-stage free power turbine is derived from the Industrial Trent and Trent 800 and is...

The MT30 is designed to meet stringent reliability and maintainability goals Excellent performance retention Maximum power and efficient fuel consumption throughout life: Turbine operates at 70°C below design limits Short and robust structure maintains gas path tolerances Operational flexibility There are no operational limitations on re-starting of the engine. After normal or emergency shutdowns, the engine can be restarted at any time. 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...

System modularity for increased availability and low cost of ownership IP Turbine Power Turbine Tail Bearing Housing The MT30’s modular design enables selected modules to be either overhauled or ‘parked’ to avoid unnecessary costs. Modularity also provides options to exchange modules between engines to reduce turnaround times. IPC & Front Bearing Housing Internal Gearbox & Intercase External Gearbox Lowest maintenance costs – less than two manhours scheduled maintenance per week Reliability Centred Maintenance studies were a feature of the engine design which together with an inherently low...

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 unmanned operation by making engine control and monitoring available over dual redundant...

A compact packaged module - simplified ship interface The MT30 design incorporates all engine accessory systems on the baseplate, simplifying installation for the shipbuilder, which is limited to providing the starter energy, plus fuel, water and electrical connections. Engineered as a modular package the MT30 permits installation in a single lift and has a variety of intake and exhaust configurations to suit ship design requirements. This concept ensures the unit arrives on site with the engine, factory tested and ready for quick, low risk installation and commissioning. The fully packaged...
