Bow Thruster · Bow/Stern Thrusters
The Schottel STT 330 is a 300 kW tunnel‑type bow thruster that delivers transverse thrust to improve vessel maneuverability, especially in confined ports and during low‑speed operations. As a Bow Thruster, it is normally installed in a bow or stern tunnel, or in a retractable housing, with an electric, hydraulic or mechanical drive and bridge control interfaces. In that role, its primary purpose is to generate transverse or steerable thrust for low-speed manoeuvring, berthing and position control. Tunnel thrusters provide lateral thrust through a fixed transverse tunnel, while retractable azimuth units can be lowered and steered to provide vectored thrust. For exact ratings, dimensions, settings, capacities, materials and variant-specific limits, refer to the manufacturer documentation for the exact figure.
What our service work and the manufacturer documentation say about keeping this model running.
Inspect propeller and tunnel or retractable housing when accessible, seals, gearbox or bearings, lubrication, motor or hydraulic drive and control feedback. Review vibration, oil condition, temperature and thrust response. Test bridge and local control under an approved manoeuvring procedure. Refer to the manufacturer documentation for the exact figure for lubrication, clearance, electrical and wear limits.
Carry seals, filters, approved lubricant, motor-control or drive spares, feedback sensors and critical hydraulic, steering or electrical components.
