The vessel, under a Mongolian flag, capsized some five-six km off the harbour area of the Paradip port, about 100 km from state capital Bhubaneswar.

Although 26 crew members have been rescued, one is still missing.

'The Ukrainian engineer who is missing may be alive. That is why we went and conducted the search. The intention was to save him,' Bux said.

'We went on the request of the engineer's family from Ukraine and a request from the office of the Consulate General of Ukraine in India,' Bux said.

Bux, 44, entered the Guinness Book of World Records for crooning for a cricket album underwater in Saudi Arabia in 2007. He claims he stayed underwater for over seven hours.

Bux is also an artist and is often seen in Oriya music albums.
