Types of surveyTypes of survey

Initial survey (issuance of International Anti-Initial survey (issuance of International Anti-Fouling System Certificate)Fouling System Certificate)

- newbuilding- existing ship, before the International

Anti-fouling System Certificate is issued for the first time.

Subsequent survey (endorsement on the Subsequent survey (endorsement on the Certificate)Certificate)

-- anti-fouling system is changed or anti-fouling system is changed or replaced replaced

may be needed upon transfer a ship to the flag of another may be needed upon transfer a ship to the flag of another State State

10


Repairs generally do not require a survey.

Repairs affecting approximately 25% or more of the anti- fouling system, should be considered as a change or replacement of the anti- fouling system.

Survey procedure for NewbuildingSurvey procedure for Newbuilding::

The surveyor make sure that:The surveyor make sure that:

-- a request for survey, together with a request for survey, together with ship’s ship’s data (data (Name of ship; Distinctive number or letters; Port of registry; Gross tonnage and IMO number), is received

12


- a declaration from the manufacturer is received, confirming that the system is in

compliance with the Convention and such a declaration should provide the

information on: - Type of anti-fouling system

- Name of anti-fouling system manufacturer

- Name and colour of anti-fouling system

- Active ingredient(s) and their CAS number(s)

13


Survey procedure for Newbuilding:Survey procedure for Newbuilding:

The surveyor should verify:The surveyor should verify:

-- verify that anti-fouling system specified by verify that anti-fouling system specified by the the documentation complies with the documentation complies with the Convention;Convention;

-- verify that anti-fouling system being applied verify that anti-fouling system being applied is is the same as described in the survey the same as described in the survey request request

14


Survey procedure for NewbuildingSurvey procedure for Newbuilding

Means of verification Means of verification

- checking that the product identification on anti- fouling system containers

- Sampling of the anti-fouling system (in most case, wet paint from the paint container)

- Testing of the anti- fouling system

- - other checking on siteother checking on site

Organotin which act as chemical catalystsOrganotin which act as chemical catalysts

small quantities of organotin compounds acting as a chemical catalyst are allowed, provided that they are present at a level which does not provide a biocidal effect to the coating. On a practical level, when used as a catalyst, an organotin compound should not be present above 2,500 mg total tin per kg of dry paint.

Example of Organotin which act as chemical catalystExample of Organotin which act as chemical catalyst

Silicone elastomer fouling control coatings are Silicone elastomer fouling control coatings are classified as biocide-free, they function purely by classified as biocide-free, they function purely by providing a physical effect, i.e. a ‘non-stick’ slippery providing a physical effect, i.e. a ‘non-stick’ slippery surface. Silicone coating often contain organotin surface. Silicone coating often contain organotin catalysts which are added to speed up the initial catalysts which are added to speed up the initial hardening (curing) of the coating film and control the hardening (curing) of the coating film and control the type of film formed, directly after application to the type of film formed, directly after application to the vessel. vessel.
