Its benefits on the environment have been ignored, say experts

VISAKHAPATNAM: The National Ship Design and Research Centre (NSDRC) here organised an international workshop to disseminate information on ‘antifouling paints and their impact, alternatives available to the shipping industry’ here on Friday. It also attempts to evaluate the present day knowledge of the impact of the tributlytin (TBT) and its ban on all stake holders. NSDRC is chosen as one of the seven partners for an European Commission’s project on “Assessment of impact of TBT on multiple coastal uses’.

As part of this project, the NSRDC is also organising this workshop to disseminate knowledge of the impact of the International Marine Organisation (IMO) ban on organisation based antifouling paints and its impact on the shipping industry.

Speaking on the occasion, the Chief Operating Officer of NSDRC, N.V. Rao stressed the need for greater research in to the issue, because there was a view that the ban was based on biased assessment According to him, environmental benefits of TBT have been ignored and little thought had been given to a technical rather than a legislative solution to control TBT inputs to the environment. Long term bio-cidal properties of existing alternatives are largely untested, he said.

Director (Technical) of Hindustan Shipyard Limited here, Commodore Naresh Kumar said that the shipyard had been using international paints permitted by the IMO and it has no problems. ‘TBT paints are definitely out as there was an IMO ban, but since there is lack of clarity on many issues, deeper study is needed. It is a challenging task for the scientists to find suitable alternatives’ he said.

Vice-Chancellor of the Andhra University, B. Satyanarayana who formally inaugurated the workshop by lighting a lamp, congratulated the NSDRC for organising such in important workshop and hoped that it would find out suitable solutions for issues concerning shipping industry.
