Our dedicated service department delivers high-precision interventions on the most prestigious engine and generator brands in the marine industry. From routine maintenance to complete overhaul, our technicians operate directly on board or at your port of call — ensuring minimal downtime and maximum operational reliability.

Our Marine Engine & Generator Service covers the full lifecycle of your vessel’s power systems — from routine scheduled maintenance to emergency on-board interventions. We work with the most respected brands in the industry, including Caterpillar, MaK, Cummins, Yanmar, John Deere and Mitsubishi for main engines, and Kohler, Mase Generators, Onan, Fischer Panda and Northern Lights for generators.

Every intervention begins with a thorough diagnostic assessment, using advanced tools to identify performance issues before they become critical failures. Our certified technicians then carry out precision maintenance or complete overhaul work — directly on board at your port of call, or at a facility of your choosing.

We understand that engine downtime means vessel downtime, which is why our Marine Engine & Generator Service team prioritizes speed and reliability in every job. With a global network of partners and a rapid-deployment capability, we can reach your vessel wherever it operates.

All our engine service procedures are performed in accordance with manufacturer specifications and comply with IMO marine engine regulations, ensuring your vessel remains fully certified and operational at all times.
