MT30 completes US Navy milestone

06 Aug 2004

The Rolls-Royce MT30 marine gas turbine engine has completed another major development milestone required for operation by the US Navy by successfully carrying out endurance test running for American Bureau of Shipping (ABS) certification. The 36MW marine gas turbine is already well positioned for two leading-edge US Navy programmes having been selected for initial production version of Littoral Combat Ship (LCS) and the DD(X) multimission destroyer Engineering Demonstration Model.

MT30 is also included in the baseline design for the two proposed Royal Navy aircraft carriers and is being actively considered for the Franco-Italian FREMM frigate programme. Completion of 1,500 hours endurance testing at 100F (38C), proved its ability to maintain power at high ambient temperatures. Inspection has shown the gas turbine to be in extremely good condition after testing.

This latest achievement follows DNV (Det Norske Veritas) design approval earlier this year, which certified the engine at 36MW to DNV?s rules for classification of High Speed, Light Craft and Naval Surface Vessels.

The company is also currently promoting the MT30 to a number of shipbuilders and shipowners involved in the transportation of LNG. RR hopes that the gas turbine will be used to power the next generation of very large LNG carriers up to 250,000 cubic metres. The installation of a gas turbine on deck just aft of the accommodation block will give the gas carrier an extra 10 to 15% carrying capacity.

The gas turbine has 80% commonality with the Trent 800 aero engine, which has won a market-leading 44% of the Boeing 777 program, achieving more than five million flying hours since entering service in 1996.
