WinGD X92DF User Manual

8.16 Stop the engine - general
You can stop the engine from the locations that follow:
•
At the bridge or engine control room (ECR) with remote control
•
At the backup control panel in the ECR
•
At the local control panel of the engine.
Related to the situation and to the planned tasks after engine shutdown, WinGD recommends to
operate the engine with marine diesel oil (MDO) for some time before you stop the engine, refer
to section 8.13 Change-over from HFO to MDO manually.
For a DF engine that operates in gas mode are the procedures related to the conditions as
follows:
•
The operator pushes the STOP button
When the operator pushes the STOP button, the ECS starts the procedures that follow:
○
The ECS changes to stop mode, thus the related control system stops the gas
supply and releases the pressure in the gas inlet pipes.
○
The ECS de-energizes the solenoid valve on the gas admission valves (GAV), thus
the gas flow to the cylinders stops.
○
The ECS stops the operation of the pilot fuel valves after the crankshaft has turned
360°, thus makes sure that all gas in the combustion chambers burns.
NOTE: If the crankshaft cannot turn 360°, the ECS sends a signal for an exhaust
ventilation request.
•
The ESS or ECS sends a cancelable shutdown signal
The engine safety system (ESS) or the ECS sends a cancelable shutdown signal, when a
related failure or defect occurs. The procedures are as follows:
○
The ECS changes to diesel mode, thus the related control system stops the gas
supply and releases the pressure in the gas inlet pipes.
○
The engine continues to operate in diesel mode until the shutdown signal becomes
active.
○
If the operator cancels the shutdown signal within the specified period, the engine
continues to operate in diesel mode.
•
The ESS or ECS sends a non-cancelable shutdown signal
The ESS or the ECS sends a non-cancelable shutdown signal, when a related failure or
defect occurs. The procedures are as follows:
○
The ECS changes to diesel mode, thus the related control system stops the gas
supply and releases the pressure in the gas inlet pipes.
○
The ECS de-energizes the solenoid valve on the gas admission valves (GAV), thus
the gas flow to the cylinders stops.
○
The ECS stops the engine.
○
The ECS sends a signal for an exhaust ventilation request.
