Kongsberg Swing Up Tcnsc Azimuthing Thruster

The TCNS type azimuth thruster offers all the advantages of a retractable thruster within an exceptionally compact design. The TCNS type azimuth thruster offers all the advantages of a retractablethruster within an exceptionally compact design. When operational, the thrusterprovides high bollard pull, ensuring efficient positioning and manoeuvring of thevessel. For transit and operations in shallow waters, the thruster can be swung upabove the baseline and retracted into its housing. The TCNS type azimuth thruster plays a vital role in the vessel’s safety redundancy system. Its powerful thrust enables the vessel to maintain control and manoeuvrability, allowing for a safe return to port if the main propulsion fails. In its stowed position, the thruster remains flush with the vessel’s keel, avoiding protrusion below the baseline—a crucial feature for operations in shallow waters and for eliminating any unnecessary hydrodynamic drag while in transit. These units can be rapidly swung down and incorporate an improved nozzle design with the thruster lower section angled 5° downwards when fully deployed. This offset directs the propeller slipstream to limit the Coanda effect, which can reduce effective thrust. The angle of tilt can be manually increased by 3.5° to obtain the best thruster performance match to the hull. Units are supplied complete with a small hull module carrying all the lifting, locking, steering and transmission systems. In the stowed position the thruster does not protrude below the vessel’s keel/ baseline, an important consideration for shallow water operations. Additional azimuth thrusters are often located at the lowest possible position in the hull due to space envelope restrictions, especially for equipment mounted at the bow, and thrusters need to be retracted into the hull when not in use. Available in powers from 750 to 2,000kW.
