Cargo Liquefaction & Can Test

Posted 5/18/2019

The most severe dangers related to cargo transportation are well addressed in the IMO Codes are those that have an adverse effect on the ship’s stability, the structure of the ship, the safety of the crew and the stevedores. The IMO has set a list of bulk materials that may behave like liquids in International Maritime Solid Bulk Cargoes (IMSBC) Code. However, these characteristics may not be clarified in shipment documents. Some cargoes have the potential to accumulate, moisture or allow its flow through its parcels. These cargoes may liquefy due to their natural characteristics that allow accumulation and humidity migration.

 

Consequently, some cargoes that are subject to liquefaction during their transportation may shift. A shift of dry cargo, such as grain, may also occur affecting the stability of the loaded ship. If a ship’s master, suspects excessive moisture in cargo, he may contact a can test during loading with the presence of a P&I surveyor preferably. This test cannot verify the content of water, but if it fails, this will be objective evidence that water in the commodity is excessive and should not be loaded.

 

Seven videos, which UK P&I Club Loss Prevention has produced in partnership with global cargo experts Minton Treharne & Davis (MTD), explain what a can test is and what it looks like in practice.
