DNV Approved Steering System, Electronic Tie Bar
Drawing 402057
This steering system is provided for a research
vessel that is equipped with two independent
rudders.
The two rudders are independently controlled via
two separate amplifiers (7173-KAS).
The forward helm station has the 7198 FFU
controller that will allow synchronized or split
rudder control in FFU mode and independent
control in NFU mode.
Also, an autopilot is integrated into the steering
system to provide synchronized rudder control.
The aft helm station allows the steering to be
operated via the FFU controller 7198 providing
synchronized or split rudder control, a dynamic
positioning system that will control both rudders to
hold the vessel in position while in DP mode, and a
joystick system that will control both rudders.
The NFU mode available at the 7198 units can be
used in case of any failure to the FFU system.
In addition, a hydraulic helm is provided in the
steering compartment to allow steering of the
vessel in case of total power loss.
Steering position indicators that are independent
from the control system are also available at
different locations.
