# Rolls-Royce Marine Olympus

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

## History

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.
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.
