Rolls-Royce turbo-generators efficiently convert steam energy to electricity and have been installed on all UK nuclear submarines and a number of surface ships.
Designed for supportability from the outset, COTS components have been adopted where appropriate and many components like pumps, motors and valves are inter-changeable which reduces the spares holding.
Turbine and generator are mounted on a single baseplate for ease of installation and to minimise noise and vibration. Multiple control valves are used to maximise part load efficiencies. Control is through a modularised hydraulic or an all-electric system.
