The Rolls-Royce Marine Olympus is a marine gas turbine based on the Rolls-Royce Olympus aircraft turbojet engine.

History

[edit]

The first Marine Olympus was built for the German Navy. In 1962 BSEL was contracted to provide the gas-generator and Brown Boveri was contracted to provide a two-stage long-life marine power turbine. A test bed was built for extensive shore trials. Construction of the ship which was intended for gas-turbine power was abandoned. Test running of the next marine Olympus began in 1966. The power turbine was of a single stage operating at 5,600 rpm utilising wide-chord blades. Beginning its sea trials in early 1968, Turunmaa, a 700-ton corvette of the Finnish Navy was the first Olympus-powered warship to enter service, some six months before HMS Exmouth, the first British ship which had been refitted to trial the propulsion system for the Royal Navy.[1]

The TM1 and TM2 variants comprised a power turbine baseplate carrying the turbine and the gas generator mountings, and differed significantly only in the construction of the power turbine structure, which was a steel casting on the TM1 and a fabrication on the TM2. All TM1 and TM2 installations were fitted with an A-rated gas generator, serial numbers 2013xx.

The TM3 comprised a similar power turbine baseplate plus a gas generator enclosure, an air intake enclosure, and many support services including ventilation and fire extinguishing systems. All TM3 installations were fitted with a B-rated gas generator, serial numbers 2017xx.
