Tunnel thrusters

This is a very compact hydraulic tunnel thruster.
The hydraulic motor is inside the lower bulb housing, and is directly connected to the propeller shaft.
These are made of steel, and are fairly simple build, no driving gears sets and only a few bearings inside, for easy repair and very little maintenance.
The bulb is the heart of the thruster and is simple to dismantle from the support.
There is very little space needed inside the vessel as no hydraulic motor or electric motor on top.
The system is very fast reversible because of the hydraulic system.

advantages

The advantages of hydraulics

  • Significant cost savings. Cheaper to purchase, cheaper to maintain and repair.
  • Less damage. No bevel gears, no drive shafts, special seal system. 
  • Shorter delivery times. Thanks to an advanced production process.
  • Simple, quick and easy to assemble, no e motor or hy motor on top.
  • Choose for yourself where to install the engine.
  • Greater flexibility on-board. Besides the propeller, with a hydraulic power pack you can also power other systems, such as a crane, a winch or even a generator. As a result, you need less diesel engines to do the same thing.
  • Optimal manoeuvrability. From full steam ahead to full astern in 2 seconds. also ideal for dynamic positioning.
  • Super-compact, good performance, low noise level, can also run on bio-oil.
  • Optimise performance. Better performance and lower fuel consumption due to optimal water flow.
