Tunnel thrusters are primarily used for docking, slow speed
maneuvering, emergency steering and station keeping at zero or
slow forward speed. Tunnel thrusters are installed transversely
in the bow or the stern of a vessel.
Electric drive tunnel thrusters with fixed
pitch propeller are available from 250 to 3,000 HP. They
are designed for variable speed electric motor input, either
DC with SCR control systems or AC with variable frequency drives.
Most of them are used in dynamic positioning applications. Read More
Engine
driven tunnel thrusters for direct engine drive are available
in the range of 250 to 3,000 HP. The engine must be provided
with a marine gear with a reduction ratio to match the input
speed of the thruster. A cardan shaft connects between
the output shaft of the marine gear and the input shaft of the
thruster. Read
