Bringing a laid-up or stacked vessel back to sustained, classed operation is not a long maintenance list. It is a controlled reconstruction of confidence — in the steel, the systems, and the records that prove both.
The sequence that holds
- Condition survey first. A cold, honest assessment of hull, machinery, propulsion, DP, electrical and safety systems against current Class and statutory requirements.
- Defect and recovery register. Every finding captured with its criticality, recovery scope and acceptance route — the spine the whole reactivation runs against.
- Recommissioning, system by system. Power, propulsion, DP, automation and safety systems brought back in a deliberate order, each tested before the next depends on it.
- Class reinstatement. Surveys, trials and documentation driven through to a clean Class position — not a provisional one.
The record groups that decide return-to-service
A reactivation is judged on what it hands over: the survey and its closeout; the defect register reconciled; the recommissioning and trials results; the Class reinstatement evidence; and the operating documentation the crew will actually use. When those record groups are complete and witnessed, the vessel is not just running — it is defensibly back in service.
