Ship's Hatch Opened Twice Despite No Ventilation During Voyage

According to the crew's report, the hatch or ventilation port was not opened for ventilation during the voyage, as the ship was transporting cargo from a cold region to a hot region. However, there were two specific occasions when the hatch was opened. In Singapore, the hatch was opened to remove fumigation residues, and on another occasion, it was opened to inspect the cargo.
