The vessels
were built between 1985 and 2002 and each will be equipped with four
new MTU 12V 4000 M53B diesel gensets, as part of the Royal Navy's vessel
life extension program.
The diesel gensets, which each deliver 1,650 kW, will be delivered from
late 2016 to Devonport Naval Base, where the repowering work is being
carried out by Babcock Marine. The deal also includes a comprehensive
logistics package for the provision of spare parts and introductory
training package. The MTU brand is part of Rolls-Royce Power Systems
within the Land & Sea division of Rolls-Royce.
Once the new engines are in place, Rolls-Royce will be responsible for
the total power output of the Duke-class frigates. The propulsion system
will comprise Rolls-Royce Spey SM1A or SM1C gas turbines with the MTU
diesel gensets, enabling the vessels to accelerate to up to 28 knots.
The diesel gensets include sophisticated noise and shock control technologies,
alongside exceptional reliability. Their low space requirement also
makes them easy to integrate into the frigate's existing engine room. |
