This is due to cost and per- formance considerations. It is clear that most ship operators are not informed about the available tin-free technologies and are not aware that there are prod- ucts, which are equal in performance to TBT-based antifoulings. Considerable experience with tin-free antifoulings is found in Japan, as the Japanese were first to ban the applica- tion of TBT antifoulings in 1992. Thus, much development work on alternatives has come from Japanese based marine paint companies, such as Chugoku Marine Paints, Ltd. Chugoku Marine Paints has experience in new generation tin-free antifoulings, mainly due to its 50 percent market share in its home country of Japan. CMP has now coated more than 8,000 vessels with their tin- free technology. There are four mainstream tin-free technologies available and Chugoku Marine Paints are unique in providing all four technologies. This allows unbi- ased advice to be given to ship opera- tors.
