ELECTRONICS STEERING SYSTEM BLOCK Below is an example of a steering system for a supply vessel that is DNV approved. The port and the stbd system are both independent and each has its own controller. Local control in the steering compartment is available via the local panels, 6511-LP, which normally overrides the control from the wheel house. From the main helm station, you can steer the vessel using the NFU jog levers which are controlling the rudders independently, using the FFU lever to operate the rudders in closed loop independent or synchronized format, using the DP system, the autopilot...
