Next-Generation Coating: Planning the Dry Dock Choice

External antifouling/fouling-release systems follow the AFS Convention, certificate/declaration, coating approval and Biofouling Guidelines; PSPC does not govern them and service life does not extend statutory/class docking intervals.

Operational Explanation

External antifouling/fouling-release systems follow the AFS Convention, certificate/declaration, coating approval and Biofouling Guidelines; PSPC does not govern them and service life does not extend statutory/class docking intervals.

Regulatory Reference

AFS Convention; 2023 IMO Biofouling Guidelines; flag/coastal/local restrictions; HSSC and UR Z3 for separate survey intervals.

Scope of Application

External-hull antifouling. Maker service-life claims must be validated for hull condition, operating profile, application quality, idle periods and warranty.

Procedure / How to Complete It

  1. Verify AFS Certificate/Declaration and controlled substances.
  2. Check specification/type approval and local restrictions.
  3. Plan surface preparation/application and biofouling management.
  4. Validate claimed life against real profile/warranty.
  5. Fit maintenance within due survey windows; obtain separate IWS/EDD approval.

Practical Example

A coating claimed for ten years may reduce renewal scope/cost but does not move the due bottom survey.

What Typically Goes Wrong

Using MSC.215 PSPC for external antifouling or claiming coating life avoids statutory dry-dock entries.

What the PSCO Checks

Evidence of the approved arrangement, procedures, records, competence, defect management and consistency with statutory/class/maker requirements.
