Full power operation of its first production MT30 gas turbine-powered main genset for the US Navy was reported in December by Rolls-Royce. Specified for the DDG-1000 USS Zumwalt destroyer programme, the MT30 achieved full power at 36MW during running at the US Navy’s test site in Philadelphia.
The MT30’s selection for the DDG-1000 programme marked the first time that the US Navy had ordered a large gas turbine for driving a genset to provide electrical power for propulsion and onboard systems throughout a ship. Targeting growing demand by navies for higher rated gas turbines in the 34-40MW power range, the compact MT30 can be configured for mechanical or generator drives.
A high power density also favoured the specification of MT30-based plant for Lockheed Martin’s contender for the US Navy’s littoral combat ship programme, headed by USS Freedom. The class features a CODAG configuration incorporating a pair of MT30s. In addition, the UK Royal Navy’s new Queen Elizabeth-class aircraft carriers will be powered by an integrated all-electric installation based on MT30-driven gensets. MP
