Statement of Compliance for Ships in Temporary Lay-up
A ship in temporary lay-up is not exempt from class and statutory obligations: the survey regime is reduced but not eliminated, and reactivation requires a dedicated survey before returning to service.
Operational Explanation
When a ship is placed in temporary lay-up for commercial reasons, the Classification Society may issue a Statement of Compliance (or Confirmation of Class for lay-up) attesting to a reduced survey regime specific to the conditions of a non-operational ship: lower frequency of inspections on some systems, but continued essential checks on hull integrity, fire-fighting and bilge systems, and mooring.
Returning to service always requires a reactivation survey, which verifies that all systems are fully operational and compliant before the ship can resume commercial navigation.
Regulatory Reference
There is no single dedicated IMO instrument for lay-up; practice is based on the class rules of individual Classification Societies ("Lay-up" or "Cold/Warm Lay-up" procedures), supplemented by Flag Administration requirements for maintaining statutory certificates during the period of inactivity.
Scope of Application
Ships placed in temporary lay-up for commercial reasons (oversupply, awaiting new employment, financial restructuring), with responsibility shared between the owner, the Classification Society and the Flag Administration.
Procedure / How to Complete It
- Formally notify the Classification Society and the Flag Administration of the intention to place the ship in temporary lay-up, before the period of inactivity begins.
- Agree with the Classification Society the applicable lay-up level (cold lay-up with minimal crew, or warm lay-up with greater operability maintained) and the corresponding survey regime.
- Maintain the essential checks required during lay-up: hull integrity, fire-fighting systems, bilge systems, mooring, even without full operability.
- Plan the reactivation survey well ahead of the expected return-to-service date, covering all systems suspended during lay-up.
- Verify with the Flag Administration the status of statutory certificates during and after the lay-up period, since some may require renewal or a specific endorsement on return to service.
Practical Example
Example: a ship placed in cold lay-up for 8 months receives from the Classification Society a Statement of Compliance suspending routine surveys on some machinery systems not in use, while maintaining periodic inspections on hull integrity and fire-fighting systems; the return to service is preceded by a full reactivation survey 3 weeks before the resumption of navigation.
Real Cases
Common Mistakes Mistake Library
| Mistake | Consequence | How to avoid it |
|---|---|---|
| Notification of lay-up to the Classification Society and Flag Administration made late or informally | Reduced survey regime not formally recognized, with full survey obligations still applicable | Formally and promptly notify both competent Authorities of the start of lay-up |
| Essential checks (hull, fire-fighting, bilge, mooring) neglected during lay-up on the assumption the ship is 'non-operational' and therefore low risk | Undetected deterioration that lengthens and complicates the reactivation survey | Always maintain the essential checks required by the agreed lay-up regime, regardless of commercial non-operability |
| Reactivation survey planned too close to the expected return-to-service date | Delays in returning to commercial service if the survey finds non-conformities to correct | Plan the reactivation survey with adequate lead time before the resumption of navigation |
PSC Observations
Operational Tips
- Always formally notify the Classification Society and Flag Administration of lay-up before the period of inactivity begins, not after the fact.
- Do not neglect the essential checks required by the agreed lay-up regime, even without commercial operability.
- Plan the reactivation survey well ahead of the expected return-to-service date, to absorb any non-conformities that need correcting.
Checklist

- Lay-up level (cold/warm) agreed with the corresponding survey regime
- Essential checks (hull, fire-fighting, bilge, mooring) maintained during the period of inactivity
- Reactivation survey planned with adequate lead time before return to service
- Status of statutory certificates verified for the lay-up period and for return to service
