According to the industry guidelines in the ISGOTT Guide and assuming terminal regulations do not require otherwise, what action should be taken to drain accumulated water from the deck during cargo handling operations in rainy conditions?
The accumulated water is to be drained periodically and the scupper plugs to be immediately closed once the water has been run off. Water containing oily residues is to be transferred to a slop tank or other suitable receptacle.
The scupper plugs are to be kept closed and sealed; any volume of water that is not contained should be allowed to flood over the fishplate.
During periods of heavy rain, it is considered prudent and safe to allow water to drain continuously; therefore scupper plugs should be removed in such conditions.
The accumulated water is to be transferred to a spare tank.

Most fruit cargoes carried under refrigeration require introduction of fresh air into the cargo space to remove any excess carbon dioxide and ethylene produced by respiration of the cargo and sensors are fitted to detect these gases. Shipper’s instructions will often indicate “constant air change” as a requirement for a cargo. Why, even though this is a crude method for controlling the cargo space atmosphere, is this type of instruction given?
It is the standard method and it is always done that way for simplicity.
Fresh air helps to acclimatise the cargo to the prevailing ambient conditions.
Some cargoes are very sensitive to ethylene levels and it may be difficult to accurately measure the low levels that would affect a cargo.
As much fresh air as possible should always be introduced into the cargo space throughout the voyage to maintain cargo quality.
