Rolls Royce Rim Thruster

Using permanent magnet motor technology increases efficiency and makes the installation more compact only the variable frequency drive unit is housed in the thruster room freeing up.

Rolls royce rim thruster.

The moving part of the ring is a rim around the propeller blades which carries a series of strong permanent magnets. Reduced installation time for. The moving part of the ring is a rim around the propeller blades which carries a series of strong permanent magnets. They will cover the speed range up to 24 knots.

The permanent magnet tunnel thruster tt pm is our latest tunnel thruster design and has been engineered with reliability and through life costs as the focus. In response to our customers needs we have launched the thruster support pool tsp. Our thruster support pool provides replacement units enabling the exchange of a complete shipset of azimuth and tunnel thrusters or just a single thruster as part of a planned maintenance solution. The az pm thruster is the latest in a range of rolls royce propulsion products using its permanent magnet technology.

Rolls royce has delivered the first of its newly developed permanent magnet tunnel thrusters tt pm to norwegian company olympic shipping which will operate the thruster on their vessel olympic octopus. Admittedly this technology is not cheap and rolls royce says owners can expect about a 100 markup at the moment on pm azimuth thrusters compared to conventional systems however the advantages. This will be followed by two smaller frame sizes 085 and 100 and one larger the 150 so that this azimuth thruster series will in due course span a power range from 900kw to 5 000kw. Space saving compact thruster.

This is significant as it not only reduces the total energy consumed from ship propulsion but also reduces the total installed generation power on the ship associated infrastructure and fuel usage saving cost and space. Tunnel thrusters are positioned fore and aft on a wide range of ships and provide sideways thrust for maneuvering and holding position in rough seas. This technology is based on electric drive where the motor is in the form of a ring round the propeller. The az pm thruster is the latest in a range of rolls royce propulsion products using its permanent magnet technology.

This level of benefit is also reflected in the information published by rolls royce on its rim driven thruster technology.
