Tunnel Thrusters
Marine Propulsion Solutions is a manufacture of Standard Transverse Tunnel Thrusters for commercial vessels. Initially used in the bows of ferries and tugs, these versatile control devices soon became popular in offshore oil servicing boats and larger ocean-going craft. They permit unassisted maneuvering alongside of oilrigs, vessels, loading platforms and docks – and provide precise control at slow speeds through locks, narrow channels and bridges. Today, PT. Marine Propulsion Solutions Tunnel Thrusters are found in applications all over the world where precision vessel control is needed.
In The Hull
The Tunnel Thruster is installed atthwartship in a tunnel low down in the bow. Sometimes a second unit is installed in the stern. For dynamic positioning and station keeping, as many as five Tunnel Thrusters have been used in a single application. With 180° thrust –90° to either port or starboard — the Tunnel Thruster gives added maneuverability and control for docking and slow-speed operations.
Because the Tunnel Thruster is relatively small in its atthwartship dimension, it can be installed in a ship with fine entrance lines and can be located in the optimum position for maximum turning moment. Complete overhaul, maintenance and removal of the mechanism are often accomplished without dry-docking.
