(a) Actions a Second Engineer Should Take in the Event of a Main Engine Control System Failure:
When the main engine control system fails and cannot be rectified immediately, the second engineer must act swiftly to ensure the engine's continued operation and the safety of the vessel. The first step is to revert the engine room to regular watchkeeping arrangements, ensuring that there is sufficient manpower to monitor the situation closely. The second engineer should then initiate the changeover to emergency or local manoeuvring control. This involves switching the control from the bridge to the Engine Control Room (ECR) or directly to the local control stand, depending on the vessel's design. Ensure that the telegraph is set to the stop position on both the bridge and in the ECR before proceeding.
Next, the fuel pump control should be switched to manual operation by disengaging the governor linkage. Depending on the engine type, a cone clutch arrangement or mechanical lever may be provided to allow manual control of the fuel rack. The starting handle should be set from "stop" to "start," and the engine starting air supply solenoid valve should be manually activated to start the engine. Once the engine reaches about 10 RPM, the fuel supply should be increased, and the speed should be adjusted using the manual fuel lever or handwheel to achieve the desired RPM. Throughout this process, all engine parameters must be closely monitored and logged to ensure the engine is operating within safe limits. It is also essential to establish and maintain effective communication between the local control stand and the wheelhouse.
