Auxiliary Engine & EDG – Complete Repair & Maintenance

RCHENG Marine provides comprehensive repair, servicing, and maintenance solutions for auxiliary engines and Emergency Diesel Generators (EDG) installed onboard marine vessels. Auxiliary engines and emergency generators are essential components of a vessel's power generation system, ensuring a reliable supply of electricity for essential machinery, navigation systems, safety equipment, emergency lighting, and other critical onboard operations. Regular inspection, preventive maintenance, and timely repairs are necessary to ensure their dependable performance during normal and emergency operating conditions.

Our auxiliary engine repair services include the inspection, dismantling, servicing, and reassembly of major engine components such as cylinder heads, cylinder liners, pistons, piston rings, connecting rods, crankshaft components, bearings, fuel injection systems, exhaust valves, and other associated parts. Our experienced technical team conducts detailed inspections to identify component wear, mechanical damage, oil leakages, abnormal vibrations, and other issues that may affect engine performance and reliability.

We undertake the maintenance and troubleshooting of essential auxiliary engine systems, including fuel supply systems, lubricating oil systems, cooling water systems, starting air systems, exhaust systems, and turbocharger arrangements, wherever applicable. Our services include identifying and rectifying overheating problems, lubrication issues, fuel system irregularities, excessive smoke, abnormal engine noise, and other operational defects.

For Emergency Diesel Generators (EDG), RCHENG Marine provides specialized inspection, repair, and maintenance support to ensure the availability and reliability of emergency power generation systems. Our services cover the inspection and maintenance of diesel engine components, generator alternators, starting systems, batteries, air-starting arrangements, fuel systems, cooling systems, exhaust systems, and associated electrical connections, depending on the equipment configuration.

We also undertake troubleshooting of emergency generator starting failures, irregular engine performance, low lubrication pressure, cooling system problems, and other mechanical or operational issues. Our technical team assists with component replacement, engine overhauling, fuel system servicing, and generator-related maintenance activities based on the condition of the equipment and the vessel's specific requirements.

Following the completion of repair and maintenance activities, necessary operational checks and performance testing are carried out to verify engine performance and generator functionality. For Emergency Diesel Generators, testing may include starting performance, voltage and frequency verification, load testing, and emergency power supply checks, where applicable and authorized. All testing and maintenance activities are performed in accordance with manufacturer recommendations, vessel requirements, and relevant statutory and classification standards.

At RCHENG Marine, we are committed to delivering reliable auxiliary engine and Emergency Diesel Generator repair and maintenance services that support continuous power availability, improved machinery performance, and the safe and efficient operation of marine vessels.
