Reliable main engine repairs delivered onboard to restore performance, maintain compliance, and keep vessels operational without unnecessary delays. Our main engine repair services are designed for ship owners and operators who need critical mechanical issues resolved efficiently while protecting voyage schedules and commercial commitments.
Modern vessels depend on the main engine for propulsion, fuel efficiency, and overall operational safety. Any failure or performance drop can lead to severe operational risks, off-hire time, and regulatory complications. Our approach focuses on executing precise main engine repairs during voyages, at anchorage, or during short port calls, ensuring vessels remain productive while essential corrective work is completed.
Traditional main engine repairs often require vessels to stop operations, wait for extended port availability, or enter repair yards. This results in lost charter time, port charges, and disruptions to commercial schedules.
Our onboard repair model eliminates these challenges by deploying experienced marine engineers who perform main engine repairs while the vessel remains operational. Repairs are carefully planned and executed under controlled conditions, allowing vessels to continue sailing safely while technical issues are resolved.
This approach ensures:

Detailed inspection and analysis of main engine performance issues, including abnormal vibrations, temperature deviations, pressure fluctuations, and fuel-related problems. Accurate diagnosis allows targeted repairs that minimize unnecessary component replacement.

Execution of corrective repairs on critical engine components such as pistons, liners, cylinder heads, valves, fuel pumps, and bearings. Repairs are performed using approved methods and verified parts to ensure reliability and compliance.

Post-repair testing and adjustment to ensure the engine operates within specified parameters. This includes load testing, monitoring of operating conditions, and verification of system stability during active service.
With operational access near key maritime hubs such as Gibraltar and Algeciras, we are strategically positioned to support main engine repair requirements for vessels operating around the Strait of Gibraltar. This allows for rapid engineer mobilization, efficient spares coordination, and timely repair execution while vessels continue trading across European and international shipping routes.
All main engine repairs are carried out using marine-grade equipment, approved repair techniques, and strict safety procedures. Our engineers are trained to work under live operating conditions while ensuring compliance with international maritime regulations and class requirements.
We focus on:
Main engine repairs involve the inspection, correction, and restoration of mechanical and operational issues affecting a vessel’s primary propulsion system. These repairs are critical to maintaining propulsion reliability, fuel efficiency, and compliance with safety and environmental standards.
By executing main engine repairs during voyages or short port calls, ship operators can resolve issues promptly, avoid major breakdowns, and maintain uninterrupted commercial operations.
Our main engine repair services help vessels maintain propulsion reliability, safety, and compliance while staying operational and on schedule.
