wheelhouse
the main control panel is in the wheelhouse this control panel features
start/stop alarms signal and acknowledgment of alarms in the
wheelhouse ceiling there is a panorama three-way rudder angle indicator there
are often also two rudder angle indicators one on each bridge wing this
is a very common remote rudder angle indication system but there may be other
indicators as well according to the ship owners requirements engine control room
in the engine control room there is an alarm and signal panel according to
normal standards and to avoid possible misunderstandings it should not be
possible to operate the steering gear from this control stand
steering-gear compartment this is the room in which the actuator is located
for the model shown there are two hydraulic pumps placed on separate
foundations each power unit consists of an electric motor which is connected to
a submerged screw pump the two starter cabinets are often mounted on the
bulkhead on the top of the actuator there is a scale with degrees showing
the angle of the rudder to port or starboard and also signal transmitters
and feedbacks for remote rudder indication and steering control system
an auxilary steering gear is not required according to the rules because
the power units are regarded as backup for each other
in the next couple of pages we will present the three most used steering
modes these are autopilot non follow-up and a variant of autopilot called follow
up click the buttons to learn more autopilot non follow-up steering
follow-up steering
autopilot
the ship will automatically find its way to a preset position point along a
preset route if the ship is forced out of course the autopilot will use the
rudder to get the ship back on course
non follow up steering
nann follow-up is total manual control of the rudder movement from wheelhouse
or in emergency situations from the steering gear compartment
follow-up steering
follow-up mode is a variant of manual it allows the rudder to be locked in any
rudder angle and the system will hold it there until you move it again
