India’s ​Coast Guard and Navy continued search-and-rescue operations off the eastern coast on Sunday after a Panama-flagged cargo vessel carrying 24 crew sank, with two Chinese nationals rescued, a senior official said.

The two rescued ‌Chinese seafarers said the ​vessel developed a list on ​Friday and sank within eight minutes, forcing crew ​to abandon ship, Shyam Jagannathan, director general of India’s Maritime Administration, told Reuters.

Jagannathan said the chances of finding survivors generally fall sharply after 12 hours, but rescuers were ​continuing the search.

Twenty-two crew members remain missing from the ‌Ocean Winner, including 18 Chinese nationals, three Myanmar nationals and one ​Bangladeshi, according to the Indian Coast Guard.

The Indian Navy is closely coordinating with the Coast Guard to locate the remaining ‌crew, the Navy ​said in a post ‌on X.

The Coast Guard has sent two vessels ‌from Sri Vijaya Puram, formerly known as Port Blair, for ​the search-and-rescue operation, a Coast Guard spokesperson said.

The Ocean Winner was carrying iron ore bound ​for China after departing from India’s eastern Paradip port on Friday, according to an initial ‌report prepared from India’s Maritime Administration.

The cargo ship sank about ‌240 nautical miles from the port, according to government sources. 

The cause of the sinking was not immediately known.
