Definition & Explanation

Unlike tracking on standard dry containers – which focuses primarily on location – Ocean Container Monitoring for Reefer Shipments goes considerably further. Specialized sensors and IoT devices continuously record temperature, humidity, door events, and power supply inside the refrigerated unit, transmitting data in real time to shipper, carrier, and receiver. For perishable commodities such as fresh produce, seafood, or pharmaceuticals, this unbroken cold-chain record is both a regulatory requirement and a direct safeguard against cargo loss. Deviations from set-point temperatures trigger automated alerts, allowing intervention while the vessel is still at sea. After arrival, the logged data serves as evidence in cargo damage claims and supports inspections under food safety and pharmaceutical regulations.
