Wärtsilä Transverse Thrusters

The combination of high thrust values with compact dimensions provides additional thrust for a wide range of vessels types. In auxiliary applications, transverse thrusters support the mooring or harbour operations of merchant cargo vessels. When applied in Dynamic Positioning systems, transverse thrusters extend the DP capability of, for example, offshore supply vessels.

     Application
    • Wärtsilä transverse thrusters are available in a range from 400 kW to 3550 kW for applications in numerous types of ships, including merchant vessels, offshore support vessels, and offshore construction vessels.
    • Transverse thrusters, also known as bow thrusters, stern thrusters or tunnel thrusters, provide a side force, or transverse thrust, to support mooring operations or position keeping.
    • Transverse thrusters are available for auxiliary or AUX usage, which is mostly applicable with merchant vessels to support harbour manoeuvring and mooring operations. Where the transverse thruster is part of a dynamic positioning (DP) system, the rating for DP use applies.

    • Stena Polaris
      The Stena Polaris is a P-MAX tanker owned by Concordia Maritime. The vessel combines transport economy and flexibility with the very highest safety level. The vessel has been built to ice class 1 A specification, which means that it is well equipped to sail in ice-covered waters where broken ice can be up to 0.8 m thick.
