Cargo Liquefaction Suspected After Ocean Winner Sinks In Minutes
The MV Ocean Winner was a very large ship carrying iron ore.
It suddenly leaned to one side and sank in about eight minutes.
The ship had 24 crew members, but only two were rescued.
Search teams continued looking for the other 22 people.
Experts think water may have made the fine iron ore behave like a liquid.
If that happened, the cargo could have shifted and made the ship unstable.
Investigators will check whether the cargo was too wet and whether safety rules were followed.
They will also examine whether the ship had structural damage or was affected by rough weather.
The exact cause has not yet been officially decided.
The Panama-flagged MV Ocean Winner sank on August 22 in the Bay of Bengal, about 230 nautical miles off Odisha.
The 225-metre bulk carrier was carrying approximately 72,200 tonnes of iron ore fines loaded at Paradip Port.
The vessel reportedly developed a sudden list and sank within about eight minutes, leaving little time for evacuation.
Two of the 24 crew members were rescued, while 22 remained missing despite a multinational search operation.
Experts suspect cargo liquefaction but say structural failure, ageing, or rough weather must also be investigated.
- Who
- The 24 crew members of the Panama-flagged MV Ocean Winner; two were rescued and 22 remained missing. Indian and Chinese vessels, the Indian Coast Guard, and the Indian Navy participated in the search.
- What
- The MV Ocean Winner developed a sudden list and sank in about eight minutes while carrying iron ore fines.
- Where
- In the Bay of Bengal, approximately 230 nautical miles off the Odisha coast, after the cargo was loaded at Paradip Port.
- When
- The vessel sank on August 22; the search continued five days later and was subsequently intensified.
- Why
- The official cause remains undetermined. Experts and officials suspected cargo liquefaction, while also citing possible structural failure, ageing, or rough weather.
Cargo Liquefaction Hypothesis
Alternative Causes
What destabilized the vessel?
Cargo Liquefaction Hypothesis
Experts said excess moisture in the iron ore fines could have caused the cargo to lose its solid-like properties, shift, and produce a sudden list.
Alternative Causes
Officials and experts said investigators must also examine rough weather, the vessel’s ageing condition, structural failure, hull damage, cracks, or a structural break-up.
Were loading safeguards followed?
Cargo Liquefaction Hypothesis
The investigation should determine whether the cargo exceeded its transportable moisture limit, or whether its certificates and test results failed to reflect its actual condition.
Alternative Causes
The articles do not establish that the cargo exceeded the limit or that procedures were breached; authorities have not officially concluded that liquefaction caused the sinking.

Quotes
Captain Nakiran Velluswamy Mudaliar
Senior vice-president of a shipping company
“If liquefaction is established, it must be investigated whether the cargo was within its transportable moisture limit (TML) when it was loaded and whether the tests represented the actual cargo condition that went into the ship.”

“Such a rapid loss of stability would have left very little time for the crew to organise an orderly evacuation.”
