Vessel Bow Thruster

Vessel Bow Thruster:

Bow thrusters usually have one or more tunnels built into the bow, below the waterline in order to improve manoeuvrability.

BowThrusters can be powered by diesel engines, electric motors or hydraulic motors.We special at design and manufacture.

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.

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

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

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

•Combinable with diesel, hydraulic or electric drive
