Ships of 400 GT and above on international voyages (excluding fixed or floating platforms, FSUs and FPSOs) must have:
(1) an initial survey before the ship is put into service or before the International Antifouling System Certificate is issued for the first time; and (2) a survey when the anti-fouling systems are changed or replaced. Surveys are to ensure that the ship’s anti- fouling system fully complies with the Convention and must be endorsed on the IAFS Certificate.
