Our team recently carried out detailed troubleshooting and fault‑finding on the vessel’s Main Engine Constant RPM control system during operational checks inside the ECR. The attendance was initiated due to irregular behavior observed in the governor response and RPM stabilization, requiring a structured diagnostic approach to identify the source of the malfunction. Given the importance of constant‑speed operation for propulsion control, every subsystem was examined with precision.

The inspection began with a full review of the automation and control cabinet, including verification of power supply stability and signal integrity across all relevant terminals. Voltage measurements were taken on the governor control module, relays, and feedback circuits to detect abnormalities in command signals or RPM reference inputs. Functional checks were also performed on control loops, alarm pathways, and the propulsion control system’s response behavior to ensure proper communication between interconnected components.
