Voith Inline Thruster / Voith Inline Propulsor

Higher thrust efficiency compared to conventional thrusters

With a propeller diameter of 7.5 feet, Voith has built the world's largest transverse thruster in use today for a Danish offshore jack-up vessel. The so-called Swing-Out Azimuth Stern Thrusters which can be retracted into the vessel hull and can be turned through 360 degrees are a very specific application. This technology is particularly suitable for drilling ships and semi-submersible vessels.

The initial idea was to develop a propulsion system with minimum vibration and noise emissions. The result is a rim driven propeller powered by a permanent-magnetic electric motor. The system requires neither axle nor shaft or gearing. VIPs/VITs impress by their prompt steering and can also be retrofitted as propulsion systems or thrusters. If required, the propeller blades can be replaced individually.

A propeller that can be used for propulsion or steering. That is fascinating technology lending itself to a wide variety of applications. Voith Inline Propellers (VIP) are used as propulsion systems for passenger boats, barges and large yachts. Voith Inline Thrusters (VIT) are used as propulsion systems or thrusters.

VIP/VIT advantages:

  • more efficient transmission of electric drive power due to absence of gears and shafts.
  • higher thrust efficiency compared to conventional thrusters.
  • few movable wear parts, no seals and gaskets.
  • motor is protected against water ingress.
  • propeller is supported by a sea-water lubricated slide bearing patented by Voith.
