Compliance & inspections
Certificates
Cross-cutting catalogue of key statutory and class documents, separating capacity, cycles and issuing authority.
Which page governs. This section is a view: the authoritative treatment of each subject sits in the page of the Survey & Certification module, which carries the regulatory reference with the precise provision, the revision stamp and the content fingerprint. Where the two diverge, the page governs.
Source of record. This page is a cross-cutting overview. Each linked topic contains the detailed regulatory reference, revision stamp and content fingerprint. If a summary and its linked topic differ, the linked topic governs.

Certificate extensions
Certain statutory certificates may be extended by the Administration under the conditions and limits stated in the applicable convention, commonly to allow the ship to reach a port of survey. The three-month mechanism must not be applied generically to every document in this catalogue. Always identify the certificate-specific provision and calculate any permitted period from the date required by that provision.
Use limitations. This overview supports learning and preparation; it does not replace procedures, authority decisions, Company instructions or verification of current source material.
