Soft shut down
For the following alarms we recommend to implement soft shut down in the
power management system:
PAL 22
Lubricating oil pressure inlet engine
TAH 12
HT cooling water temperature - high
TAH 60
Exhaust temperature deviation - high
If applicant:
LAH 92
High oil mist level
TAH 58
Splash oil temperature - high
TDAH 58
Splash oil temperature deviation alarm - high
TAH 29
Main bearing temperature - high
By soft shut down the ships power management system must start the next
standby engine and transfer the load to this, following the engine with alarm
is shutting down.
Remarks to individual parameters
A. Fuel oil pressure, HFO operation
When operating on HFO, the system pressure must be sufficient to depress
any tendency to gasification of the hot fuel.
The system pressure has to be adjusted according to the fuel oil preheating
temperature.
B. Cooling water pressure, alarm set points
As the system pressure in case of pump failure will depend on the height of
the expansion tank above the engine, the alarm set point has to be adjusted
to 0.4 bar plus the static pressure. The static pressure set point can be
adjusted in the display module.
C. Lubricating oil pressure, offset adjustment
At charge air pressure below 1.0 bar the lub. oil pressure to turbocharger is
normal at 0.6 ±0.1 bar.
The read outs of lubricating oil pressure has an offset adjustment because of
the transmitter placement. This has to be taken into account in case of test
and calibration of the transmitter.
