The wet and moldy goods were discovered to be concentrated in the middle of the aft section of hold 4, beneath the manhole cover of the bottom ballast tank where a leak was detected. Based on the ballast record, this hold was filled with ballast water after discharging at Huangpu. As a result, we suspect that the inadequate sealing of the manhole cover caused the ballast water to leak, resulting in the goods becoming wet and moldy.
