The steering control system is designed according to IRS / DNV/ RINA requirements. It is Unit approved by IRS, DNV, RINA (approval is achieved as per customer requirement). We have steering control systems for solenoid operated valves. Non-follow-up (NFU) steering and follow-up steering (FU) are available. Systems for single rudder vessels and twin rudder vessels are available.

SEQUENCE OF OPERATION

The Joystick provided at the wheelhouse is used to Steer the vessel to Port side/ Starboard side.When the joystick is turned to starboard side an electrical impulse from steering control panel, inside wheelhouse goes to the DC valve of the Power pack unit in engine room. The Electric motor of the power pack unit runs a Gear Pump.

The gear pump produces Pressurized oil supply, which is regulated by PRV and fed into the DC valve. when the impulse from the Wheelhouse comes to the DC valve, the valve directs this pressurized oil to respective ports of the Actuators. This pressurized oil makes the Actuator Extend/Retract.The tiller arm connected to the actuator thus turn angularly from Left to Right. The rudder plate connected to the tiller arm by rudder stock also turns.

The rudder plate directs the stream of water coming from the propeller thus achieving the turning of vessel. For the vessel to turn to the STARBOARD side the rudder plate is turned to STARBOARD side thus directing stream of water from propeller to STARBOARD side.The rudder plate is turned to the PORT side to the vessel will turn to PORT side.
