CINS and the International Group of P&I Clubs launch set of guidelines covering the carriage of Seed Cake in containers.

Seed Cake is primarily used as an ingredient in animal feeds and is the solid residue that remains after edible vegetable oils have been removed from oil-bearing seeds, cereals or other commodities. Seed Cake can be shipped in the form of pulp, meals, cake and pellets and must be transported in compliance with the requirements set out in the IMDG Code.

Self-heating of the cargo

Neither of the two ways used to remove oils and fats from the plant material removes all of the oil and it is the reactivity of the residual oil which gives rise to the hazardous properties of Seed Cakes. The presence of oil and moisture in Seed Cake cargoes can, through a combination of microbiological activity and oxidation, lead to self-heating. The inherent moisture content will drive the microbiological self-heating and can increase the temperature of the cargo to a point where oxidation of the residual oil occurs. This can lead to further self-heating.

Oxidative self-heating can be much faster than microbiological heating and may increase the temperature in the cargo high enough for the cargo to ignite spontaneously. Hence, the higher the moisture and oil content of the cargo the higher the risk of self-heating and spontaneous ignition.

Cargo guidelines

To improve safety during the carriage of Seed Cake and to ensure it is properly declared, package and carried, CINS (the Cargo Incident Notification System) and the International Group of P&I Clubs have published joint industry Guidelines for the carriage of Seed Cake in containers.

Gard is an Advisory Member of CINS and is pleased to see that many of our Members and clients are also members of CINS.  We encourage other container line members and clients to enquire about CINS membership, the main purpose of which is to highlight and address risks posed by certain cargoes and/or packing failures in order to improve safety in the liner shipping industry.
