It is normally installed in a bow or stern thruster tunnel/compartment, with the drive motor and hydraulic/electric equipment arranged in an adjacent machinery space. Its primary duty is to generate transverse thrust for low-speed maneuvering, berthing and station keeping. In service it interfaces with electric/hydraulic drive, propeller or pod, seals, gearbox/bearings, control system, switchgear and bridge commands. For exact limits, settings, test values and approved maintenance criteria, refer to the manufacturer documentation for the exact figure.
