Statement of Compliance for Ships in Temporary Lay-up

A lay-up file connects ship arrangements, preservation, class and certificate status with conditions for return to service; issuer declarations document their own scope and conditions.

lay-upStatement of Compliancereactivation

Operational Explanation

A lay-up file keeps the ship’s arrangements, preservation activities and conditions for return traceable. Read a declaration or Statement of Compliance together with the approved or agreed plan, its scope and class and certificate status: it identifies what the issuer has actually verified or attested. Records during inactivity then support preparation of the examinations needed for reactivation.

Temporary lay-up may be warm or cold, with different crewing, active systems, maintenance and operational readiness. A society may offer a notation, declaration or document under its own terminology; there is no single IMO “Statement of Compliance” that automatically suspends surveys.

Class and statutory certificates must be managed separately. During prolonged lay-up some statutory certificates may not be maintained through periodical surveys, while class status may follow a limited regime under the Rules. Return depends on duration, preservation, modifications, overdue surveys and actual condition.

File / evidenceHow to use it
Lay-up documentIssuer, basis, identified ship, warm/cold arrangements and activities actually attested.
Inactivity conditionsLocation, expected duration, crew, mooring, safety and preservation agreed with the competent parties.
MaintenancePlan, maintenance/test records and due dates; check documented effects on class and individual certificates.
ReturnActual condition, work and modifications, overdue activities and an agreed examination programme before return to service.

Regulatory Reference

Apply the conventions and flag instructions for statutory certificates, society Rules for class and local authority requirements. One society’s procedures are not a universal regime. DNV — lay-up and reactivation.

HSSC 2025 §5.5 treats lay-up or a long period out of service for major repairs/modifications as possible special circumstances for dating a certificate following a late renewal. The Administration decides; the renewal retains its full scope and additional examinations may be needed depending on inactivity and preservation of hull and machinery. This does not automatically suspend due dates. HSSC 2025 §5.5.

Scope of Application

Ships taken out of service for commercial, technical or market reasons. Requirements and controls vary with location, duration, warm/cold mode, crewing, system status, flag, class and coastal authorities.

Procedure / How to Complete It

  1. Notify flag, class, insurers and relevant authorities.
  2. Agree the lay-up mode and status of class and certificates.
  3. Prepare safety, preservation, maintenance and test plans.
  4. Record surveys, audits and certificates falling due during the period.
  5. Derive recommissioning from actual condition, work and due dates.

Practical Example

For a ship in extended cold lay-up, Company, flag and class establish which certificates will not be maintained, which limited visits apply, and which overdue surveys, tests and checks are required before service.

What Typically Goes Wrong

Relying on the name of a declaration, assuming all surveys are suspended, or applying one predefined comprehensive reactivation scope ignores flag requirements, Rules, duration, condition and actual due dates.

Common Mistakes Mistake Library

MistakeConsequenceHow to avoid it
Treat the lay-up document as suspension of every deadlineSurveys or certificates may expire without their effects being recorded in the file.Read the document’s issuer, scope and conditions and agree in writing the treatment of class and each affected certificate.
Use a standard return programme without the inactivity fileNecessary examinations may be omitted or planned without regard to actual condition.Compare duration, preservation, work and overdue activities and agree the pertinent programme with flag/class.

What the PSCO Checks

When the ship returns to operation, PSC applies its ordinary regime and checks certificates, crewing, condition and operation. Previous lay-up neither replaces valid certificates nor by itself determines inspection priority or outcome.

FAQ

Is there one universal IMO Statement of Compliance for lay-up?
No. Document names and effects depend on flag, society and applicable arrangements.
Do surveys stop automatically?
No. Treatment of class and certificates must be agreed and documented.
Does recommissioning always require the same survey?
No. Scope depends on duration, preservation, overdue surveys, modifications and condition.
