First order for energy saving Kawasaki thruster

Four units were ordered by China Communications Import & Export Corporation (CIESCO) for delivery to Tianjin Lingang Tug Co Ltd, which plans to install them in Port of Tianjin tugboats scheduled to enter service in the second half of 2018.

Manoeuvrability

The Rexpeller can be freely rotated 360 degrees horizontally to generate thrust in any direction and thus functions as both a propulsor and rudder.

Because of the level of manoeuvrability it provides, the Rexpeller can be used on tugboats, supply boats, drillships and cable layers.

Kawasaki has achieved reduction of energy consumption with the Rexpeller of up to 7% compared to the conventional series by developing a high-performance and compact propeller duct (Kort nozzle) and optimising the lower gear case, based on the latest fluid analysis.

The company also made maintenance operations inside the ship easier by reworking the entire structure of the integrated hydraulic clutch.

In addition, expansion of inboard maintenance space, flexible hull design and easier installation have been achieved by arranging the adjacent auxiliaries compactly around the upper gearbox.

Environmentally friendly

The use of a high-quality fluororubber (FKM) propeller shaft seal help ensures high reliability and reduces the risk of ocean pollution via oil leakages. A monitoring function of the propeller shaft and steering seal is available as an option.

Kawasaki began production of Rexpeller azimuth thrusters in 1983 and has since delivered approximately 1,000 units.
