ABSTRACT:
A ship steering system includes a pump assembly for controlling hydraulicy actuated rudders, a first actuation unit for translating a helm steering command signal into a mechanical control signal for the pump assembly, and a second actuation unit for translating a combined helm steering command signal and ship roll reduction command signal into a mechanical control signal for the pump assembly. The second actuation unit includes an electrically activated mechanical actuator that translates the electrical helm and roll reduction command signal into a mechanical impulse that controls the operation of the pump assembly. The mechanical actuator includes a switch apparatus for switching the rudder control function from the first actuation unit to the second actuation unit when the switch apparatus and second actuation unit are activated. The mechanical actuator also includes an electrically activated fluid control valve that controls the flow of fluid to a rotary-vaned hydraulic actuator wherein the shaft thereof is linked to a coupling element of the switch apparatus. The coupling element is selectively engaged with a bearing member that operatively controls the pump assembly.
