Government of India has decided not to extend the special exemption to single hull tankers that are registered under Indian flag after December 31, 2009. The decision was taken in view to prevent old and unsafe single-hull tankers from sailing in Indian waters. This will also prevent import of single-hull tankers available in the international markets at scrap rates. However, the special exemption will continue for the existing single-hull tankers till 2015. The phasing out of such tankers will begin from the year 2010.

As per IMO regulations, all the tankers with a single hull are to be phased out by 2010. After 2010, only double hull tankers will be allowed to ply along with single hull tankers below the age of 25, who have the requisite permissions from their flag states and port states.
