  • Rolls-Royce is to supply 12 MTU diesel gensets with 20V 4000 M53B engines to prime contractor BAE Systems for the first three Type 26 Global Combat Ships due to go into service with the Royal Navy. (Image: MTU)
  • The four MTU diesel gensets on board each Type 26 Global Combat Ship are based on 20V 4000 M53B engines, each delivering 3,015 kW of mechanical power. (Image: MTU)
  • 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. (Image: MTU)

Rolls-Royce is to supply 12 MTU diesel gensets to prime contractor BAE Systems for the first three Type 26 Global Combat Ships due to go into service with the U.K Royal Navy. 
 
The deal means that the core components of the frigate’s combined propulsion system will come from Rolls-Royce: four MTU diesel gensets with 20V 4000 M53B engines, each delivering 3,015 kW of mechanical power, and one Rolls-Royce MT30 gas turbine. The MTU brand is part of Rolls-Royce Power Systems.
 
The Type 26 Global Combat Ship is the first newly-designed Royal Navy surface vessel to be equipped with MTU engines. It is also the first time Rolls-Royce has supplied a naval vessel with an MTU propulsion system that meets the requirements of the IMO III emissions directive. To achieve this, each of the four engines on the vessel will be fitted with an exhaust aftertreatment system, which uses a Selective Catalytic Reduction (SCR) unit to neutralize nitrogen oxide emissions. Rolls-Royce has carried out extensive testing of this technology, which has already been successfully used in MTU off-highway applications, for use in maritime propulsion systems.   
 
The Type 26 Global Combat Ship is the Royal Navy’s third major project involving MTU engines. Rolls-Royce is supplying Series 4000 diesel gensets for the refit of the Duke class (Type 23) frigates, while the Astute class submarines already have MTU diesel gensets.
 
Within the Combined Diesel-Electric or Gas Turbine (CODELOG) propulsion system for the Type 26 frigates, the MTU diesel gensets will provide electrical power for on-board electronics and for cruising propulsion. The Rolls-Royce gas turbine will be used for propulsion when travelling at high-speeds. The MTU gensets are bedded on specialist mounts and surrounded by an acoustic enclosure, ensuring that the propulsion system operates at low noise levels. A similar propulsion system featuring MTU diesel gensets is used aboard the German F-125 class frigates and French FREMM frigates.
