Rolls Royce Rim Driven Thruster

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.

Rolls royce rim driven thruster.

At the same time t. The moving part of the ring is a rim around the propeller blades which carries a series of strong permanent magnets. This technology is based on electric drive where the motor is in the form of a ring round the propeller.

The moving part of the ring is a rim around the propeller blades which carries a series of strong permanent magnets. 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. After over a decade of research and development rolls royce is heading into full production of their permanent magnet tunnel thruster from their facility in ulsteinvik norway. Rim drive propellers or rim driven propulsers and thrusters voith rdp.

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. This level of benefit is also reflected in the information published by rolls royce on its rim driven thruster technology. One key area of interest is the potential impact of rdps on hydrodynamic efficiency. Initial published research based on a scaled cruiseship model estimated that an efficiency improvement in the order of 7 was achievable.

In response to our customers needs we have launched the thruster support pool tsp.
