Bow/Stern Thruster · Bow/Stern Thrusters
Marquip MQ Tunnel 1500kW — MQ Tunnel, 1500 kW, 105.0 kN thrust; source metadata also lists power 1500.0 kW. The supplied category identifies the equipment as Stern Thrusters / Bow/Stern Thruster, and it is normally installed in a transverse tunnel or dedicated thruster compartment near the aft part of the vessel with electric or hydraulic drive and control interfaces. In that listed role, its primary purpose is to generate transverse thrust for low-speed manoeuvring, berthing and position control. Compared with the main propeller and rudder, a transverse thruster is optimized for lateral manoeuvring at low vessel speed and depends on tunnel flow, propeller condition and a high-power drive system. Within the supplied list, this variant is distinguished from neighbouring entries by its model designation and the explicitly listed power; further hardware differences are not stated in the source. No additional performance, approval or construction detail is inferred from the model code beyond the information supplied in the source record. For exact ratings, dimensions, settings, capacities, materials and variant-specific limits, refer to the manufacturer documentation for the exact figure.
Every value below comes from the manufacturer datasheet or class-society record on file for this model.

What our service work and the manufacturer documentation say about keeping this model running.
Inspect propeller and tunnel when accessible, seals, gearbox or bearings, lubrication, motor or hydraulic drive and control feedback. Review vibration, temperature and oil condition and check for leakage. Test bridge and local control under an approved manoeuvring procedure. Refer to the manufacturer documentation for the exact figure for oil, clearance, electrical and wear limits.
Carry seals, filters, approved lubricant, bearings where appropriate, motor-control or drive spares, feedback sensors and critical hydraulic or electrical components.
