What is a thruster?
A thruster is a propulsion system which is used to make ships more maneuverable. Because thrusters can be rotated, a rudder is no longer necessary. There are many different kind of thrusters, for example:
- Azimuth thrusters
- Azipull thrusters
- Tunnel/bow thrusters
How it works
The chamber between the two oil-repellent lip seals is filled with oil and the resulting pressure effectively keeps water outside and oil inside the thruster gearbox. Even in the unlikely event of damage to the water repellent lip seals, the system will still prevent any water ingress into the thruster’s lower gearbox. The oil barrier will lose its overpressure and the oil level drops, triggering the low level alarm and oil/monitoring tank to create a pressurised oil barrier.
