Purpose of Dunnage on-board ship
Dunnage can be used for the following:
1) To protect cargo from contact with water from the bilges, leakage from other cargo, from ship’s side or from double bottom tanks.
2) To protect cargo from moisture or sweat which condenses on the ship’s sides, frames, bulkheads, etc, and run down into the bilges.
3) To protect cargo from contact with condensed moisture, which is collected and retained on side stringers, bulkhead brackets,etc.
4) To provide air courses for the heated moisture laden air travel to travel to the sides and bulkheads along which it ascends towards the uptakes, etc
5) To prevent chafe as well as to chock off and secure cargo by filling in broken stowage.
6) To evenly spread the compression load for deep stowage
7) To provide working levels and protection for the cargo on which labour can operate and serve as a form of separation.
8) Provide access for cooled air round or through the cargo for temperature controlled requirements.
