Kongsberg Maritime, a Norwegian technology enterprise, has introduced a new size of underwater mountable azimuth thruster with a 3.7 meter propeller and 4.2 mw power output model joining the range.

Suited to a range of vessels including drill ships, wind farm vessels and production vessels, the UUC PM 355 features a permanent magnet (PM) motor, delivering 81 tons of bollard pull.

The UUC PM 355, features a compact design with less space required in the machine room thanks to the integrated PM motor. Other features include low noise operation, less lubricating oil volume and no oil-to-sea interfaces, Kongsberg Maritime explained.

Further, the underwater mountable thrusters can be exchanged without the need for drydocking, while the vessel remains in the water. Installation of the UUC range can reportedly be done at depths up to 50 meters.
