Bow Thruster / Tunnel Thruster

A Bow Thruster is a ship propulsion system with the purpose of manoeuvring the bow of a vessel sideways (transversal). It allows the captain to turn the vessel to port or starboard during mooring and docking without using the main propulsion. Even the most restricted areas. It can also be executed as a stern thruster.
The driving parts are assembled as one bow thruster or stern thruster system by means of a tunnel structure. This tunnel structure is built into the bow or stern part of the ship’s hull.

Drive types:
Diesel engine drive, electric motor drive, hydraulic motor drive.

Installation types:
L-drive for vertical main drive motor installation (electric motor and hydraulic motor).
Z-drive installation (often used for diesel engine drives but also electric drives).
Flexible installation (to reduce vibration).

Main applicable ship types:
Typical applications for electric propulsion ship, hybrid ship, marine surveillance vessel, unmanned intelligent ship, ferry, tourist ship, deluxe passenger ship, container vessel, fishing vessel, LPG carrier, LNG carrier, PSV, AHTS, OSV, yacht, navy vessel, etc.
