OMPI has developed extensive expertise in the maintenance and repair of fuel injection equipment for marine diesel engines. We work on 2-stroke and 4-stroke engines—including main engines, auxiliary engines, and marine generators—across low-, medium-, and high-speed applications.
We support shipowners, shipyards, repair workshops, ship repair companies, port operators, and spare parts suppliers with scheduled overhauls, urgent repairs, and technical supplies.
Proper injection system efficiency is crucial for the performance of a marine diesel engine. Pumps, injectors, pump elements, delivery valves, and nozzles must operate with precision to ensure smooth combustion and correct fuel distribution.
When these components are worn, dirty, or out of adjustment, the engine may exhibit issues such as excessive smoke, high fuel consumption, starting difficulties, power loss, or inconsistent performance across cylinders.
OMPI carries out disassembly, inspection, overhauling, component replacement, calibration, and test-bench validation. Each intervention is tailored to the specific application, as main engines, auxiliary engines, and marine generators have distinct operational requirements.
OMPI services and repairs marine injection pumps—including multi-cylinder and single-cylinder types—as well as diesel injectors. Components undergo rigorous testing to verify flow rate, pressure, sealing, timing, and spray quality.
We also supply spare parts for marine diesel injection systems and, where available, complete exchange units. This solution is particularly beneficial when customers need to minimize downtime and quickly return the engine to service.
OMPI also has expertise in applications fueled by diesel and Heavy Fuel Oil (HFO), where injection quality and proper component maintenance are critical for ensuring continuous operation.
OMPI acts as a technical partner for Italian and international clients, handling requests related to routine maintenance, major overhauls, emergencies, vessel downtime, and the sourcing of hard-to-find components.
Our organization allows us to receive components at our workshop, perform technical inspections, and determine the most suitable solution—whether repair, testing, supplying a spare part, or providing an exchange unit.
