Onboard Repair
& Maintenance
Powered by CyberSmart Smart Operation. Riding crews and specialist technicians deployed to ports worldwide for planned maintenance execution, machinery overhauls, and emergency breakdown response. Smart Operation provides vessel and crew operations management to coordinate maintenance workflows. Our goal is to minimize off-hire time, reduce drydock dependency, and keep your fleet operating safely and efficiently.
What is Onboard Repair & Maintenance?
Onboard repair and maintenance services allow vessel operators to carry out essential machinery overhauls, system repairs, and planned maintenance tasks while the vessel remains in service or during scheduled port calls. Riding crews—teams of experienced marine engineers and technicians—join the vessel at any worldwide port, bringing the tools, spare parts, and expertise needed to complete work safely and efficiently.
From main engine piston and liner overhauls to deck machinery repairs, electrical system maintenance, and hull steelwork, onboard repair services reduce the need for costly drydocking and extended off-hire periods. Combined with Planned Maintenance System (PMS) execution, these services help maintain classification society requirements and ensure continuous operational readiness.

How We Work
Every repair and maintenance engagement follows a structured process to ensure work is completed safely, on time, and to the standard required by classification societies.
Scope & Mobilization
Work scope is agreed in advance with the vessel operator and superintendent. Our riding crew is mobilized with the correct tooling, spare parts, and technical documentation. We coordinate logistics to minimize delays and ensure team arrival aligns with the vessel schedule.
Execution & Quality Control
All work is carried out to OEM specifications and class requirements. Our technicians follow structured work procedures with quality checkpoints at each stage. Photographic documentation is maintained throughout for traceability and survey preparation.
Handover & Documentation
Upon completion, all work is documented with detailed service reports, measurement records, and test results. Documentation is prepared in formats accepted by major classification societies, supporting seamless survey close-out and PMS record updates.
Frequently Asked Questions
