The 1989-built containership, Anil, has capsized during its cargo operations and sunk in Assaluyeh port in Iran.
A number of containers fell into the ocean and were still afloat in the harbour on 24 January.
According to the official IRNA news agency, the ship capsized as a result of improper box configuration at dock No. 9 at the port.
The 12 crew members of the boxship are safe, according to Maritime Bulletin.
The vessel’s last Automatic Identification System (AIS) signal was picked up at Assaluyeh at 7:30 am (local time) on 24 January.
The Tanzanian-flagged ships had left Bandar Abbas, another Iranian port.
This accident occurred on the same day a cargo ship capsized off of Nagasaki in Japan, leaving nine crew members missing and two dead.
