Captain Jaspreet Chawla and Chief Officer Shyam Chetan, who had got conditional bail in January, “will be coming to India in two days,” General Secretary of the National Union of Seafarers of India (NUSI) Abdulgani Y Serang said in Mumbai.

The two sailors of the ship, Hebei Spirit, were sentenced to jail last year by a South Korean court.

A crane barge owned by Samsung Heavy Industries collided with Spirit and led to an oil spill which endangered marine lives and resulted in loss of livehood for many.

Last year, a local court had acquitted Chawla and Chetan and blamed Samsung for the accident. But the ruling was challenged in an upper court which held them guilty on charges of negligence resulting in marine pollution. Chawla was awarded one-and-a-half years in jail and Chetan was sentenced to eight months imprisonment.

The ruling by the South Korean court sparked widespread anger in the international shipping community, including Indian seafarers unions, which insisted the tanker crew were not guilty.
