Marine Bow Thruster

Marine Bow Thruster

Usually, there is one or more tunnels built into the bow below the waterline in order to improve maneuverability. Depending on the type of vessel, the range of application for bow thrusters extends from brief docking and casting-off in ports with a limited number of operating hours every year up to continuous operation under extreme load conditions in demanding offshore applications with dynamic positioning. Marine bow thruster allows the ship to dock without the assistance of tugboats, saving the costs of such service.

Features:

1. Powered by diesel engine, electric motor or hydraulic motor

2. Electric motors are included optionally in the scope of supply. The prime mover can be connected either horizontally or vertically and thus incorporated optimally into the naval architectural design.

3. When fixed-pitch propellers are used, electric and hydraulic motors allow the direction of thrust to be reversed.

4. An additional reversing gearbox is required if the thruster is powered by a diesel engine.

5. Certificates approved: ABS, BV, CCS, DNV, GL, KR, NK, RINA, etc.

Advantages

•For extreme load conditions, e.g. in the offshore sector

•For continuous and short-time service

•Low noise emission

•Available with either fixed or controllable-pitch propellers

•Compact design due to horizontal, vertical or inclined arrangement of the power input flange
