Overview
OEM Approved, Class Aware Support
We support a wide range of marine propulsion and mechanical systems, delivering dry dock work in line with OEM guidance and class expectations.
We work alongside shipyards and class surveyors throughout the dry dock period, supporting inspections, reporting and sign-off from initial assessment through to recommissioning. Our focus is on clear communication, practical delivery and keeping projects moving without unnecessary disruption.
What this means for fleet operators and superintendents
- Clear coordination with OEMs, shipyards and class surveyors
- Fewer delays during inspections, surveys and sign-off
- Confidence that work is completed in line with OEM guidance and class expectations
- Accurate documentation to support compliance and future maintenance
- Smooth testing and handover before return to service

How We Support Vessels in Dry Dock
Pre docking Inspection
Before the vessel enters dock, we carry out detailed pre-docking assessments to define scope, identify risks and confirm required tooling, parts and resources. This ensures clarity before work begins and avoids unnecessary delays once in dock.
Project planning
We coordinate with vessel operators, shipyards and OEM guidance to plan manpower, materials and timelines. Clear communication and structured planning allow dry dock activities to progress efficiently and to schedule.
In dock excution
During the dock period, our engineers carry out inspection, overhaul, dry dock repair and installation work in line with agreed scope and class expectations. We maintain close liaison with yard teams and surveyors to keep projects moving and issues resolved quickly.
Sea trial and testing
Following completion, we support system checks, alignment verification and functional testing prior to return to service. Our focus is on ensuring systems operate as intended and the vessel leaves dock ready for reliable operation.
