Auxiliary Engine (Generator Set) · Auxiliary Engines
Typically found on large container ships and cruise liners, the 12VW20DF-GS-60Hz engine operates in a dual-fuel configuration, capable of running on LNG or heavy fuel oil. With a power output of 1260 kW at 1080 rpm, it ensures reliable operation across various marine environments. Regular maintenance is crucial to prevent common failures such as balancing shaft wear and turbocharger overheating at higher speeds, which can lead to significant downtime. Inspect the temperature of the balancing shaft bearings continuously, and ensure proper cooling systems are in place for high-speed operations. Additionally, check for signs of piston ring wear and maintain clean fuel supply to avoid issues with the injection system.
