Rolls-Royce MT30 Rolls-Royce MT30 The Rolls-Royce MT30 (Marine Turbine) is a marine gas turbine engine based on 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 25MW. Rolls-Royce announced the MT30 programming on September 11, 2001. The first run of the engine was on September 6, 2002.
