Container ships

Familiarity with reefer containers

Those who have to rely on transport of temperature-controlled goods in reefer containers need to be assured that their consignments will arrive in the required condition. The container vessel may form part of the cold chain. During carriage by sea, cargo officers must be able to properly care for the reefer cargo whilst it is on board their vessel. To be able to monitor effectively and to maintain the condition of the cargo, ship’s officers must have knowledge of the various reefer types and must understand how they work.
