Refrigerated containers, commonly referred to as reefers, are used for the transportation of perishable goods. When unloaded at a terminal they need to be connected to a reefer plug on shore to keep the goods refrigerated until they are picked up by a truck and taken to their final destination.
Hong Kong-based container shipping company Orient Overseas Container Line Limited (OOCL) said that challenges to the discharge and handling of reefer shipments at the Shanghai, Tianjin, and Ningbo terminals continue to persist because of the extraordinary demand for reefer plugs.
