How it works
SeaStar hydraulic power steering uses the ship’s engine(s) to provide
the “power” for the steering system, via an engine or electric motor
driven hydraulic pump.
A manual hydraulic steering system, consisting of a standard SeaStar
helm and a hydraulic steering cylinder, (fitted with an integral servo
cylinder and a power steering valve) supplies the “control” portion
of the steering system.
Under normal conditions, with engines running, a hydraulic oil supply
is in a stand-by mode, ready to be directed to the steering cylinder
as dictated by the steering wheel, servo cylinder and power
steering valve.
Turning the steering wheel left or right makes the system go from
stand-by into operating mode and move the steering cylinder accordingly.
In the event of a power source failure, hydraulic oil, from the steering
helm, is automatically diverted directly into the servo and steering
cylinder, providing the helmsman with manual back-up steering.
An engine room mounted oil reservoir allows easy system fill and
assists the in-line oil cooler in cooling the hydraulic oil. An in-line oil
filter helps to protect the steering system components against
contaminants.
