Dynamic Positioning Systems


Dynamic Positioning Systems include Minehunting Propulsion and Control System and Steering System.

Minehunting Propulsion and Control Systems

The Minehunting Propulsion System, with two or three retractable azimuthal thusters, provides an unparalleled manoeuvrability to the vessel in all the MCM operations in order to facilitate search and identification of underwater targets, ROV and boats launch and recovery without exposing at risk the vessel itself, the operators and high value assets such as ROVs, VDS, etc.

The System has been designed with the aim of providing an extremely low signature to the vessel when sailing in minehunting mode, either acoustic and magnetic, coupled to an effective shock resistance.
Extensive testing have been performed to verify all these features with extremely satisfactory results.

The vessel design with separated Minehunting Propulsion and the transit propulsion, offers an high speed transit with good efficiency, and an extremely precise and silent operation during minehunting, along with the "take home" capability.

The Complete System is controlled by a Remote Control System that can be complemented by lightweight consoles in the different ship rooms, or can be integrated to the Ship Navigation Control System.

The system includes a dedicated autopilot MHAP-20 specifically developed for Minehunting operation featuring specific algorithms to enhance dinamic positioning precision and minimize required power and hence noise, that has been also supplied to customers using a different propulsion configuration.

Main features

  • Shock tested with explosion at sea ( MIL-S-901)
  • Marginal residual magnetic signature
  • Extremely low underwater noise emission
  • Extremely high manoeuvrability level
  • Propeller thrust up to 3000 Kg

Steering Systems

Calzoni designs and manufactures complete Steering Systems hydraulically operated with relevant steering stand and controls in accordance to shipping registers regulations and Naval specific requirements.
The system includes controls, Hydraulic Power Unit actuators and if required by the customer the rudder axis with sealing and the rudder itself.

The steering stand includes the autopilot that can be configured to perform a range of tasks such as track keeping, course keeping, target following, etc.

Redundancy provides a high degree of safety to ensure continuous operations even in presence of external damages and failures.

Main features

  • Shock qualified
  • Vibration qualified
  • Noise qualified
  • EMI qualified
