TBT-FREE ANTIFOULINGS--THEIR EFFECT ON SHIP OPERATION

Of all the antifouling coatings applied worldwide, 60 to 70 percent are self-polishing copolymers. These products offer large financial benefits to the ship operator that have come to be accepted as commonplace: five-year drydocking intervals, and significant fuel savings from exceptional control of fouling and hull roughness. These coatings, however, rely on tributyltin (TBT) for their effectiveness, and TBT is the subject of mounting legislative pressure that arises from environmental concerns. This paper explains the legislative situation with regard to TBT as of 1990, what is likely to happen in coming years, what new coatings products are available as alternatives, and what steps shipowners should take to prepare themselves for the changes that are imminent.
