Tunnel Thruster · Bow/Stern Thrusters
A high‑power hydraulic tunnel thruster from Kawasaki, delivering up to 1800 kW of bow thrust through a compact tunnel housing for improved maneuverability of large vessels. As a Tunnel Thruster, it is normally installed in the steering-gear room, bow or stern thruster compartment, or propulsion-control system according to the listed equipment. In that role, its primary purpose is to control vessel heading or generate transverse or directional manoeuvring thrust. Ram and rotary-vane steering gears, tunnel thrusters and retractable azimuth units use different actuators and propulsors but all depend on reliable hydraulics or electric drives and feedback control. Power: 1800 kW; capacity: 500-3000 kW. For exact ratings, dimensions, settings, capacities, materials and variant-specific limits, refer to the manufacturer documentation for the exact figure.
