Efforts were underway to douse the flames on the M T Genessa tanker which was carrying 30,000 tonnes of high-speed diesel, he said.
The official said water sampling has not shown any oil spill so far in the Arabian Sea from the tanker, anchored 15 nautical miles off the Deendayal Port in Kandla.
The fire in the oil tanker's crew compartment was reported last evening. The Indian Coast Guard had evacuated all the 26 crew members, two of whom suffered burn injuries.
Defence PRO, Gujarat region, Abhishek Matiman today said no oil spill has been reported so far from the tanker.
