Permanent magnet tunnel thruster
The TT-PM is engineered and built with focus on reliability and efficiency. The core mechanical technology is well proven and verified through rigorous design processes, quality control, testing and verification.
Reliable, efficient and low through life cost
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. 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 space on board.
It also simplifies maintenance as the patented mount means units can be removed and replaced without drydocking. PM thrusters are currently available in two sizes with powers of 1,000 and 1,600 kW. These thrusters have been developed for the most demanding applications such as dynamic positioning.
- Efficient and space saving PM technology
- Fast response times to full power
- Rugged design with high reliability
- Equal thrust in both directions
- Patented resilient mounting system reduces noise and vibration, simplifies tunnel fabrication and removal/installation
- Oil filled stator for superior cooling and protection
- Robust centre shaft carries all propeller loads
