Steering gear

 

Main steering gear components

We offer steering gear which has proved highly successful under high-load operating conditions in a large variety of vessels.

The main components of the Simplex-Compact steering gear comprise a vane steering motor (type VSM) and an electro-hydraulic power unit (type HPU).

The vane steering motor has been designed with an integrated rudder carrier and radial bearing. The steering gear is a high-performance unit suitable for all types of vessels and rudder designs, where high speed of reaction or very wide angles is required.

This steering gear complies with SOLAS/IMO regulations.

Automatic shut-off valves are fitted as standard at the connection points of the hydraulic double power unit.

In the event of ruptured pipes or oil leakages in the power units, the appropriate side of the system is shut off, thus preventing any drop in pressure in the steering motor.

 

Additional features of this steering gear

Hydraulic systems

Simplex-Compact steering gear is available with a choice of three standard hydraulic systems.

  • constant pump supply and rudder rate: binary system with electro-mechanical on/off valves and constant-supply pumps
  • variable pump supply: analogue system with proportionally controlled variable delivery pumps
  • variable oil supply: analogue system with electo-mechanical proportional valves and constant-supply pumps.

 

Motor starter boxes

The motor starter boxes have all the necessary alarm and safety features, and they comply with IMO/SOLAS regulations, as well as classification society requirements.

 

Additional roll-damping effect (RRS rudder system)

The RRS rudder systems represent real state of the art technology. The basic principle is based on the fact that the rudder movements required for a ship’s steering and the rudder movements required for roll damping can be superimposed.

The steering gear uses a combination of robust vane steering motors and accumulator-supported hydraulic power units to achieve the higher rudder rates required to achieve a significant roll-damping effect.
