Underwater Demountable Azimuth Thrusters

Thrustmaster Underwater Demountable Azimuth Thrusters are designed to be mounted and dismantled underwater, so units can be installed after launch and exchanged without dry-docking or taking the vessel off station. This is critical for semi-submersible drilling rigs and large DP vessels operating 24/7.

Key features

• Three-part installation system: receptacle with outer cap, inner cap, and thruster
• Receptacles built by Thrustmaster and shipped to the shipyard; caps factory-installed and protect the topside until the thruster is mounted
• Removing the caps gives access to the hydraulic steering motors and the cardan drive shaft attachment
