Marine Systems and Components

We design and manufacture turnkey propulsion systems according to specific customer requirements. We are integrators of complete conventional propulsion systems for all types of ships.

Retractable fin stabilizers (SS type) with fin surface from 3 m² up to 10 m². This product was designed and built for fast ships.

We have also designed and engineered shock resistant stabilization systems for military applications.

Route Control System (RCS): based on an integrated control system of the stern unit (interceptor) and fin stabilizers. These hydraulically operated devices maintain optimum platform trim and reduce accelerations due to pitch, roll and heave motions.

The frigates of the Italian-French FREMM program mount the rudder roll governance and stabilization system. This system both reduces rolling and keeps the ship on course. The system has special shock resistance qualities and a torque range of 50 - 500 kNm.

In this field, we supply the following components:

 •   Bow and stern thrusters

 •   Retractable and non-retractable azimuth thrusters

 •   Control systems

Fincantieri has developed two transverse thrusters:

 •   HMF type with fixed pitch propeller;

 •   HMC type with controllable pitch propeller.

These two configurations have the same high level of performance in that the propellers are made with very high precision machine tools.

Both types of propellers use a flexible coupling to connect the main engine to the transmission pinion. The bevel gear, consisting of pinion and crown, which transmits power to the propeller, is made with very high precision hardened teeth.

Features of tunnel thrusters:

 •   Suitable for cruise ships, ferries and all types of naval vessels

 •   Proven reliability and sturdiness on hundreds of ships operating worldwide.

 •   Impact resistance qualification, closing tunnel hatches for reduced underwater acoustic signature and to reduce the ship's forward motion resistance with consequent fuel savings.

 •   The new "hubless" type operating with a permanent-magnet motor is in the process of development and testing. This new type of propeller delivers unique noise and energy saving performance. These features are much appreciated especially on luxury pleasure boats.

The azimuth thrusters were developed according to the very strict standards of the naval and offshore sector.

The two ART (retractable) and AT (non-retractable) series can be used for dynamic positioning and for the main and auxiliary propulsion.

The retractable propellers can be quickly raised and lowered from inside/outside the ship. The ART model has been designed for inspection without the vessel needing to enter dock. This feature is made possible by a patented system that uses a mountable/removable cover to create an airtight chamber to repair or replace the propeller.

The non-retractable AT model comes with all the necessary equipment to be dismantled and replaced at sea with the help of specialist divers.

Mounting and alignment of the ART type inside the ship takes place through the provision of a welded steel structure customized and incorporated into the propeller. This simplifies the work of integration and interface with the hull at the construction site.

We design and manufacture a wide range of systems for handling and access to cargo for naval vessels and passenger ships and yachts.

The product range for naval vessels includes bow or side ramps, goods hoists or platforms with high load capacity, covers, hangar doors and others.

For cruise ships we offer customized solutions for access of personnel and cargo handling, including full lateral load systems.

We are able to provide tailor-made products to meet our customers' specific requirements.

• Stern doors and ramps

• Sealed dock doors

• Side and ramp doors

• Hatchways and coverings

• Goods hoists and elevator platforms

We have extensive experience in the design, supply and installation of special equipment in both merchant and naval fields. We possess the know-how and expertise to provide "turnkey" CALM/SALM offshore marine terminals for the Oil & Gas sector.

In addition to the design and construction of new terminals, we provide upgrade and/or repair services for critical components on existing terminals.

The services we offer in this field are:

• Studies and simulation of the optimal positioning of the terminals 
• Evaluation of the mooring system
• Design
• Procurement and construction
• Installation and supervision of commissioning
• Project management
• Quality control
