Abstract : A ship steering system includes a pump assembly for controlling hydraulically 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 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. A decoupling device is interconnected to the first and second actuation units and the pump assembly for decoupling the first actuation unit from the pump assembly when the second actuation unit is activated.
