Tognum subsidiary MTU Friedrichshafen GmbH and Rolls-Royce have jointly been awarded the contract to design the diesel generator sets for the Royal Navy´s future Type 26 Global Combat Ship. BAE Systems made the announcement at the International Defense and Security Equipment exhibition (DSEi) in London. The propulsion system will consist of a combination of four MTU diesel gensets powered by Type 20V 4000 M53B engines, and a Rolls-Royce Type MT30 gas turbine.
Combined propulsion systems utilizing diesel engines and gas turbines are increasingly gaining in significance in the naval sector. The future Type 26 Global Combat Ship will employ a CODLOG (Combined Diesel Electric or Gas Turbine) configuration. The diesel generators supply electric power for the on-board systems and for vessel propulsion in cruising mode. The Rolls-Royce gas turbine can be switched in for high-speed propulsion whenever need. The propulsion concept is ideally suited for the mission profiles of future ships. For naval applications, the MTU gensets have double-resilient mounting systems and are housed within acoustic enclosures. This creates a propulsion system with an extremely low level of acoustic emissions, making the ship very difficult to locate.
