Even though Indian Government has okeyed ratification of Bunker convention last year India has not yet ratified the Bunker convention.

But India has ratified the CLC 92 convention. Even though the original CLC 69 did not cover the pollution from the tanker in ballast and pollution from the bunker oil of the tanker. In the 1992 amendments to the CLC convention, few changes were brought including that CLC 92 covers pollution from the bunker oil also.

Now there was a bunker pollution incident off Chennai following the collision of tankers "BW Maple" and "Dawn Kanchipuram". 

So in this incident, the costs will be covered by insurance set up by the vessels in question under CLC convention 92.
