Bow thruster for ships (tunnel type, electric)
L DRIVE
ZF Marine
In addition to the conventional tunnel thruster arrangement where the tunnel is welded integral to the vessel's structure with the gearbox bolted directly onto the mounting flange, it is also possible to suspend the thruster in rubber. In this manner the thruster is isolated from the hull and direct contact between tunnel and hull construction is avoided. This reduces "structure borne noise" significantly.
The flange arrangement also makes it possible to remove the thruster from the vessel without drydocking, provided
that the vessel can be trimmed so the outerwell flange is above the waterline for removal.
