Fincantieri finalizes new generation of efficient tunnel thrusters

The Fincantieri Marine Systems Business Unit introduced a new family of tunnel thrusters that advance comfort, reliability, environmental sustainability and energy efficiency.

According to Fincantieri, a leading maritime classification society validated and certified the thrusters' hydrodynamic optimization as achieving the lowest levels of vibration and noise available on the market.

5%-10% fuel savings

Fincantieri credited a cutting-edge patented system of tunnel closure elements (thruster shutters) for ensuring a significant reduction in hull drag and total required propulsion power, with fuel savings between 5% and 10%.

The solution entails high transversal thrust performance (optimized hydrodynamic flow), mechanical protection of propeller (assembly designed to act as a grid) and compactness.

Fincantieri said the design pays the utmost attention to maintainability criteria in order to minimize drydock requirements and enable maintenance while a ship is in the water.

Part of a Green Package

The tunnel thruster system, completed by the tunnel closure for a perfect hull when underway, is part of Fincantieri's Green Package of top-performing marine equipment.

Other elements include fin stabilizers for energy savings and environmental protection through a patented grease lubrication and a high-efficiency heat recovery system dedicated to on-board application.
