The Panama-flagged bulk carrier Ocean Winner has sunk in the Bay of Bengal, resulting in the disappearance of 22 seafarers. The incident occurred approximately 230 nautical miles southeast of Paradip, where the Indian Coast Guard initiated a search and rescue operation on August 22 after losing contact with the vessel.
The Ocean Winner was carrying a total of 24 crew members, including 20 Chinese nationals, three Myanmar nationals, and one Bangladeshi national. A distress alert broadcast through the International Safety Net prompted assistance from passing vessels, leading to the rescue of two survivors from life rafts by the tanker Aisopos.
The Search Efforts
The Indian Coast Guard has mobilized three ships to aid in the search for the remaining missing crew members. The search operation underscores the increasing focus on maritime safety as the International Transport Workers’ Federation (ITF) has called for an immediate investigation by Panama, the vessel’s flag state. The ITF expressed its condolences to the families of the missing personnel.
Risks of Cargo Liquefaction
This tragic incident has reignited discussions about the hazards associated with cargo liquefaction in bulk carriers. Liquefaction occurs when moisture content in certain bulk cargoes causes them to behave like a liquid, threatening vessel stability and potentially leading to capsizing with minimal warning. Iron ore fines are particularly vulnerable to this phenomenon.
The recent report from the International Association of Dry Cargo Shipowners (INTERCARGO) highlights that cargo liquefaction has been a significant factor in incidents involving bulk carriers, accounting for more than half of the fatalities in such casualties over the past decade. Seventeen bulk carriers of 10,000 deadweight tons or more have sunk worldwide between 2016 and 2025, resulting in 71 deaths.
The Ocean Winner incident follows earlier casualties like the sinking of the Devon Bay while carrying nickel ore, where an initial investigation suggested excessive moisture caused a sudden shift in the cargo. With this trend of vessel casualties, INTERCARGO continues to urge shipowners, operators, and seafarers to exercise extreme caution when transporting susceptible cargoes, especially under adverse conditions.
The Operational Read
The sinking of the Ocean Winner serves as a stark reminder of the persistent dangers inherent in bulk shipping, particularly concerning liquefiable cargoes. Operators need to enhance their risk assessment protocols and ensure rigorous compliance with safety guidelines during loading and transport. The rising incidents of cargo liquefaction underline the necessity for improved weather monitoring and load assessment technologies. As search operations continue, the broader industry must consider enhanced training for crews on managing such risks, to prevent future tragedies.
