Anti-fouling Systems—Sampling

1. Anti-fouling Systems—Sampling Huang Tianbing Marine Biosafety Section Bangkok, June 2009 Views expressed in this presentation are those of the author and should not be construed as necessarily reflecting the views of IMO or its Secretariat.

2. AFS—Sampling • ARTICLE 11 - Inspections and detections of violations • A brief sampling of the ship’s anti-fouling system that does not affect the integrity, structure, or operation of the anti-fouling system taking into account guidelines developed by the Organization .

3. AFS-Sampling • ARTICLE 11 (continue) • The time required to process the result of such sampling shall not be used as a basis for preventing the movement and departure of the ship

4. AFS—Sampling • Guidelines for brief sampling of anti-fouling systems on ships, adopted by resolution MEPC.104(49). • - Main body provides general terms; • - Appendices provide examples of sampling and analytic methods

5. AFS—Sampling • 1 When sampling is needed • 2 General terms to be observed during sampling • 3 A brief introduction of sample analysis • (two steps, thresholds and tolerance limit )

6. AFS—Sampling • Inspections or surveys do not necessarily always need to include sampling of anti‑fouling system (paragraph 1.3 of the Guidelines). • Reliable documentation (AFS Certificate or SOC) would sufficiently verify a ship’s compliance • Majority of relevant industries have been refraining from the marketing, sale and application of organotin compounds since the adoption of the Convention

7. AFS—Sampling • For practical reasons sampling of the anti-fouling system is very often reserved for occasional checking or where there are clear grounds for believing that the anti-fouling system intended to apply or presenting on the hull does not in compliance with the Convention.

8. AFS—Sampling • Sampling may be needed in the following cases: • .1 occasional checking of an anti-fouling system applied at new-building ; • .2 occasional checking of an anti-fouling applied at a maintenance and repair dry‑docking; • .3 an existing ship requesting an IAFS for the first time; • .4 port State inspection

9. AFS—Sampling • Sampling from wet paint • 1 Take samples from a newly opened container; • 2 Stir the paint to ensure even consistency before sampling; • 3 Take the samples and store them in appropriate sealed packaging; • 4 For coatings where on-site mixing of several components is required, take samples of each component, and record the required mixing ratio; • 5 Record details of the paints; • 6 Triplicate specimens

10. AFS—Sampling • Sampling from dry paint from ship’s hull • 1 Not to affect the integrity of anti-fouling systems; • 2 From the surface is intact, clean and free of fouling

11. AFS—Sampling • 3 Avoid contamination • of samples • 4 Triplicate samples at • least 4 sampling points

12. AFS—Sampling • 5 Take photographs of hull and sample areas

13. AFS—Sampling • Sampling device

14. AFS—Sampling

15. AFS—Sampling • Personal safety • 1 Safe access to sampling points • 2 Avoid contact with paint

16. AFS—Sampling • Safe access to sampling points • − Condition of the ship (ballast condition, ship’s operations, mooring, anchorage, etc...) • − Surroundings (position of ship, traffic, ships movement, quay operations, barges or other floating vessels alongside) • − Safety measures for the use of access equipment (platforms,cherry picker, ladders, etc...) • − Weather (sea state, wind, rain, temperature, etc...) • − Precautions to avoid falling into the water between the quay and the ship.

17. AFS—Sampling • Sample analysis

18. AFS—Sampling • ICP /MS: Inductively Coupled Plasma/ Mass Spectrometry • ICP-OES:Inductively Coupled Plasma /Optical Emission Spectrometer • AAS: Atomic Absorption Spectrophotometer • XFR: X-ray fluorescence analysis • GC/MS: Gas Chromatography/mass spectrophotometry

19. AFS—Sampling Atomic absorption spectroscopy

20. AFS—Sampling • Inductively Coupled Plasma

21. AFS—Sampling

22. AFS—Sampling • X-ray fluorescence (XRF)

23. AFS—Sampling

24. AFS—Sampling • GC-MS

25. AFS—Sampling • Field-Portable GC/MS

26. AFS—Sampling • “Tolerance range” means the numerical range added to the threshold value indicating the range where detected concentrations above the threshold value are acceptable due to recognised analytical inaccuracy and thus do not compromise the assumption of compliance. • Less than 30% tolerance range.
