Workboat Code Certification & Survey Requirements

Every Workboat Code certificate is time-limited and survey-dependent — it's not a one-off assessment. This guide covers how certification is obtained and maintained, and why an expired or lapsed certificate is a live risk a Master has to actively manage, not paperwork someone else handles.

Initial Certification

Before a vessel can operate commercially under the Workboat Code, it goes through an initial survey against the standard for its intended Category and Area of operation — construction, stability data, watertight integrity, machinery, and safety equipment fit are all assessed together as a package matched to that operating profile.

Ongoing Survey — Why It Doesn't Stop at Day One

Certification isn't permanent. Vessels are subject to periodic surveys through the certificate's validity period, plus a full renewal survey before the certificate expires. Between formal surveys, the vessel still has to be maintained in the condition it was originally assessed in — a certificate reflects the vessel as surveyed, not the vessel as it happens to be today if maintenance has slipped.
