fincantieri / marine systems and components Transverse Tunnel Thrusters

— The use of transverse tunnel thruster application is a must as it remarkably facilitates the ship evolution when manoeuvring in narrow waters or at low speed. This low-cost solution allows to achieve remarkable safety conditions and is also time-saving, the use of tug boats being no longer necessary. Since the beginning of the ‘60s Fincantieri has been joining the experience acquired in the production of controllable pitch propellers with the skills of high performances shipbuilders, and can offer a product of high efficiency and reliability, designed for easy installation and maintenance...

transverse tunnel thrusters — This type of thrusters - with fixed pitch propellers - is normally driven by hydraulic or electric variable speed motors, but it exists an alternative type driven by an internal combustion engine and a reverse gear. The main standard characteristics are: low cost; monoblock high efficiency propeller; possibility to be furnished in blocks and bolted in a tunnel previously arranged by the yard in accordance with Fincantieri drawings.

Electric Motor Speed (rpm) Main dimension Di (mm) A (mm) B (mm) Control System — The standard remote control from the control stations is of electrical/electronic type. It incorporates a device to allow the starting of the equipment only when the blade pitch is at zero setting and the hydraulic unit is correctly operating. Control systems for bow and stern thrusters - run by a joystick interfaced with the ship automation system - can also be supplied. Antipollution Sealing System — Fincantieri can apply a special antipollution system on the seals of the propeller shaft, which can be...
