STABILIZATION, PROPULSION, POSITIONING AND GENERATION SYSTEMS
COMPONENTS THAT MAKE A SYSTEM
We design and integrate advanced systems for stabilization, propulsion, dynamic positioning, and power generation, with the goal of ensuring high performance, energy efficiency, and operational reliability in every scenario.
PROPULSION
PROPULSION SYSTEMS
Fincantieri is at the forefront of developing electric and hybrid propulsion systems, integrating electric motors, batteries, fuel cells, and low-impact generators.
The solutions are designed to:
- reduce CO₂ and NOₓ emissions;
- improve energy efficiency;
- ensure operational continuity even in zero-emission mode.
Among the most recent projects:
- LSS, PPA and LHD class ships for the Italian Navy, equipped with hybrid propulsion systems supplied by Fincantieri SI;
- CSOV and SOV units for offshore wind, built by VARD, featuring electric propulsion and next-generation dynamic positioning systems;
- the “Sun Princess,” the first LNG-powered cruise ship delivered in 2024, a symbol of the Group’s energy transition.

STABILIZATION
STABILIZATION SYSTEMS
Fincantieri’s stabilization systems ensure maximum comfort for passengers and crew by reducing roll and improving navigation safety. The solutions include:
- active and retractable stabilizer fins;
- gyroscopic systems;
- adaptive automatic control based on weather and sea conditions.
These technologies are essential for cruise ships, yachts, and military units, where stability is a critical requirement for operational efficiency and onboard experience quality.
STABILIZER FIN PRODUCT RANGE
+
Retractable stabilizer fins (sr model) with fin surface from 2 m² to 22 m², with or without flap; opening (aft-bow or bow-aft).
Fixed stabilizer fins (sf model) with fin surface from 1.3 m² to 18 m²
Fixed stabilizer fins with functionality also at zero speed (sfz model), designed for applications on large yachts to ensure a high level of comfort both underway and at anchor.
STEERING SYSTEMS PRODUCT RANGE
+
AVAILABLE CONFIGURATIONS
- Hydraulic servomotor
- Hydraulic cylinders and linkages
- Torque range: 30 – 2,500 kNm
MAIN FEATURES
- High efficiency
- High reliability
- Compact dimensions
- Shock resistance (for military ship applications)
APPLICATIONS
- Offshore Patrol Vessels (OPV)
- Destroyers
- Frigates
- Corvettes
- Amphibious ships (LPD)
RUDDER ROLLS PRODUCT RANGE
+
The “rudder roll” steering and stabilization system is installed on the Italian-French FREMM program frigates. This system reduces roll while maintaining the vessel’s course. It features special shock-resistance characteristics and a torque range of 50 – 500 kNm.
THRUSTERS
THRUSTER SYSTEMS
Dynamic positioning (DP) systems allow naval units to automatically maintain position and heading, even in adverse weather and sea conditions, without the use of anchors. These technologies are essential for:
- offshore operations;
support for energy platforms;
underwater interventions and military missions.
Fincantieri integrates sensors, control algorithms, and actuators to ensure precision, reliability, and redundancy, even in high-criticality environments.
In this context, we directly supply the following components:
- stern and bow thrusters
retractable and non-retractable azimuth thrusters
control systems
stern and bow thrusters
TUNNEL THRUSTERS
+
Fincantieri has developed two configurations of transverse maneuvering propellers:
HMF type with fixed-pitch propeller;
HMC type with controllable-pitch propeller.
Both configurations deliver the same high level of performance, as the propellers are manufactured using ultra-precision machine tools.
Both types of propellers use a flexible coupling to connect the main motor to the drive pinion. The bevel gear, consisting of pinion and crown, which transmits power to the propeller, is made with hardened teeth of extremely high precision.
Tunnel thruster features
- Suitable for cruise ships, ferries, and all types of military vessels
- Proven reliability and robustness on hundreds of operational ships worldwide
- Shock resistance qualification, tunnel closure doors for reduced underwater acoustic signature and to minimize hull resistance during forward motion, resulting in fuel savings
- A new “hubless” type driven by a permanent magnet motor is under development and testing. This new propeller design achieves unique performance in terms of noise reduction and energy savings—features highly valued especially on luxury yachts.
PRODUCT RANGE
AZIMUTH THRUSTERS
+
Azimuth thrusters have been developed according to the stringent standards of the military and offshore sectors.
The two series, ART (retractable) and AT (non-retractable), can be used for dynamic positioning and for both main and auxiliary propulsion.
Retractable thrusters allow quick raising and lowering from inside/outside the vessel. The ART model is designed to be inspected without docking the unit. This feature is made possible by a patented system that uses a removable cover to create a watertight chamber for repairing or replacing the propeller.
The AT model, non-retractable, is equipped with all the necessary equipment to be dismantled and replaced at sea with the assistance of specialized divers.
The installation and alignment of the ART type inside the vessel is achieved through the supply of a customized welded steel structure integrated with the thruster. This simplifies the shipyard’s integration and interface work with the hull.
APPLICATIONS
- Drilling ships
- Semisubmersible crane vessels
- Offshore construction vessels
- Offshore supply/service vessels
- Military vessels (auxiliary propulsion)
PRODUCT RANGE
OFFSHORE
OFFSHORE MARINE TERMINALS
We rely on extensive experience in the design, supply, and installation of special equipment for both commercial and military applications. We have the know-how and expertise to deliver turnkey offshore marine terminal projects (CALM/SALM) for the Oil & Gas sector.
In addition to designing and building new terminals, we provide upgrade and/or repair services for critical components on existing terminals.
The services we offer in this field include:
- studies and simulation of optimal terminal positioning
- mooring system evaluation
- design
- material procurement and construction
- installation and commissioning supervision
- project management
- quality control
ENGINES
DIESEL ENGINES AND GENERATION SYSTEMS
Through its subsidiary Isotta Fraschini Motori S.p.A., Fincantieri produces a complete range of high-speed diesel engines, with power outputs from 250 to 3,600 HP, for:
- onboard power generation (main or emergency);
- naval propulsion;
- railway traction and military vehicles;
- industrial and oil & gas applications.
The IF1300 and IF1700 series engines feature high-pressure electronic injection (HPCR), comply with emission regulations, and are also available in non-magnetic versions for military applications.
AN INTEGRATED AND SUSTAINABLE ECOSYSTEM
Stabilization, propulsion, positioning, and generation systems are an integral part of Fincantieri’s technological platform, which combines mechatronics, power electronics, automation, and artificial intelligence. The result is a naval ecosystem capable of adapting, learning, and optimizing its performance in real time.
