Retractable Thrusters
High maneuverability and station-keeping capability
The Retractable Azimuth Thruster operates in full azimuth mode when deployed as part of an auxiliary propulsion system to increase the vessel’s station-keeping capabilities. A tunnel can be incorporated in the design of the outer well so that the thruster can be used as bow thruster as well.
Typical applications for the propulsion system are OSV, research vessels, jack-up, stand-by and rescue vessels. The thruster is designed with a performance range 100-2,500 kW.
