When HFO is used for maneuvering, the fuel must be heated sufficiently. This keeps
the viscosity at the fuel pump inlets in the range given in 0710−1, Fig. 1
Viscosity-Temperature Diagram.
The heating of the fuel oil system must stay set to on. Keep the temperature of the
cooling media as close as possible to the higher limits given for usual service (see
0250−1 Operating Data Sheet).
3. Usual Operation
3.1 Control Room Maneuvering Stand
To start the engine in speed mode with a fixed pitch propeller do as follows:
1) Make sure that the MCM−11 module is set to on.
2) In the LDU−20 MAIN page, select the Speed Setpoint button.
3) Set the applicable speed.
4) Push the the START AHD or START AST button.
3.2 Local Control Panel
See also 4003−1, Engine Control, paragraph 3.
3.3 Transfer and Accept Control from ECR Remote to Local
1) At the ECR console LDU−20, get the CONTROL LOC. Page (see 4002−2,
paragraph 3.4).
2) Push the button Local for control to the local manual control.
3) At the local control panel LDU−20, push the button CTRL. TR. to get control.
4) Get the MAIN page.
5) Use the rotary button to select the Fuel Command button to between 12% and
30%.
Note: The recommended range for the start fuel setting is between 12% and
30%. A setting of less than 12% will not be sufficient for engine start. A
setting of more than 30% will cause too much smoke.
You can also use the Speed Setpoint button to operate the engine.
Use this operation mode for long periods only when necessary e.g. until defects in the
speed control system, or other defects in the remote control can be repaired.
In installations with controllable pitch propellers or clutch couplings, more precautions
are necessary. There must be good communication between the bridge and the local
manoeuvring stand.
Note: The speed control is part of the engine control system (ECS). An engineer
must stay at the local manoeuvring stand. The engineer can then make
changes immediately if necessary.
