Testing and Certification

In 2002, the first MT30 development engine, the D1, was produced and testing began in August of that same year. The initial purpose of the program was to complete proof of concept, and initial functional testing of the engine. The first D1 engine test was successful, and demonstrated the robustness of the engine design. In March of 2003, after achieving 258 hours of running, including 126 hours of endurance testing, the D1 engine was removed, following the development of the D2 engine. In June, 2003, the second development engine, the D2, began functional testing. The D2 engine was built close to production standard, and included a large level of instrumentation. The development of the D2 aimed to clear the majority of operational and functional requirements required for the final MT30 engine. Testing of the D2 engine concluded in August of 2003, after 110 hours of functional testing.

, following the successful testing of the D1, and D2 engines, commenced a program of testing aimed at clearing the MT30 engine for an ABS approval. This required for the MT30 engine to successfully complete 198, 8 hour operation cycles for a total of 1500 hours of running time. The ABS test was successfully completed in July, 2004. Only one significant issue arised during the test, a bearing was damaged due to debris being trapped by magnetic chip detectors in the oil system, which was later fixed. Following the successful ABS test, the MT30 was certified for production.https://torroja.dmt.upm.es/congresos/asme_2011/data/pdfs/trk-17/GT2011-45484.pdfhttps://www.rolls-royce.com/~/media/Files/R/Rolls-Royce/documents/defence-aerospace/VCOMB3258-MT30-Marine-Gas-Turbine-Brochure.pdf

Engineering information

The Rolls-Royce MT30 is based upon the well-established, successful Rolls-Royce Trent 3-shaft architecture, which utilizes three independent shafts, each one rotating at different optimal speeds, connecting different turbine stages to different compressor stages. The MT30 Gas Turbine, shares significant commonality with the Aero Trent engines, used in the

Power Output

The MT30 Gas Turbine, is flat-rated to provide 36MWb of output power, via inlet temperatures ranging from -40°C to +38°C. If required, alternative engine ratings can provide up to 40MW of power at a 15°C inlet temperature. The MT30 is capable of delivering high power outputs at high-ambient air temperatures, a unique feature of the engine.

advantages of gas turbines, it is imperative that the gas turbine package is as compact as possible.

has therefore developed a 'Compact Package' for the MT30. The Compact Package has a footprint of 8.6 m x 2.7 m , with a weight of 30 tons. The MT30 Compact Package is designed to operate under the following enviromental conditions: * External Air Temperature, -35°C to +50°C * Seawater Temperature, -2°C to +40°C In order to ensure the maintainability of the MT30 GT, large removable panels have been fitted rather than conventional opening doors, due to the minimum space available around the gas turbine. Furthermore, lightweight temporary deck-mounted platforms, which are fitted in pre-defined slots, allow safe and easy access to the gas turbine and the appropriate ancillary systems.
