Repair Main Engine Speed Control System

Repair Main Engine Speed Control System

In the intricate dance of maritime operation, the heartbeat is the Main Engine (M.E) speed control system. However, as vessels traverse the unpredictable seas, challenges may arise, impacting the efficiency of this critical system. Among the formidable issues faced is the failure of the main engine, specifically stemming from the malfunction of the Drive Gear Unit (DGU) servo drive unit and DGU servo AC supply. The onset of a 3-phase AC supply failure alarm for the ME DGU servo leaves ship personnel unable to mitigate M.E RPM. Compounding the complexity, the engine local control telegraph LED for the Astern side remains dark during the lamp test, thwarting the replacement of the defective LED.
