Emergency Steering Instructions
This overview is intended for the use of instruction for the manual operation of the ship’s
steering units. See diagram on reverse side for further details of mentioned assemblies if
necessary.
The hydraulic steering unit itself is composed of an Emergency Pump and Valve Arrangement
(RED INDICATING MOTOR COLOR), AND A main Pump and Valve Arrangement (BLUE
INDICATING MOTOR COLOR). The Emergency Pump is the smaller of the two, and is located
in the upper portion of the steering unit. To determine which pump is in operation, feel the
forward end of the motor and detect airflow from its fan. USE ONLY THE PORT STEERING
UNIT IF THE VESSEL IS OPERATING ON EMERGENCY POWER.
ÿIF THE MAIN UNIT (BLUE INDICATING COLOR MOTOR) IS RUNNING×
1. locate the 2 blue colored solenoids on the aft end of the Steering Unit –
approximately mid-point on the assembly. The small brass pins located on the aft
ends of the solenoids are the manual control operators. See diagram on reverse
side for further details.
PUSH THE PIN ON THE VALVE MARKED “L” TO TURN LEFT RUDDER
PUSH THE PIN ON THE VALVE MARKED “R” TO TURN RIGHT RUDDER
ÿIF THE EMERGENCY UNIT (RED INDICATING COLOR) IS RUNNING×
1. Locate the red cylinder on top of the steering unit. The “T-Bar” assembly facing aft from
the cylinder is the manual control operator. To engage the emergency unit steering
control – push the “T-Bar” in (forward), and rotate handle a full 180 degrees. You can tell
that the “T-Bar” is engaged by feeling its resistance to motion in both directions
PULL OUT “T-BAR” TO TURN LEFT RUDDER
PUSH IN ON “T-BAR” TO TURN RIGHT RUDDER
2. Rotate “T-Bar” 180 degrees and pull out (aft) to disengage steering.
FURTHER INFORMATION: Thruster angle indicators are positioned outboard of each
steering unit on the thruster shaft cages. The port unit also is equipped with a gyro repeater
housed directly above the thruster shaft cage. Communication to the bridge during steering
operations is made ready by a sound-powered phone located on the bulkhead at mid-ships.
