Evergreen Marine's 58,000 reefer containers are now IoT-enabled, enhancing cold-chain monitoring and improving cargo quality and delivery security.
In long-haul transportation, whether a refrigerated container maintains a stable temperature and whether its equipment is operating normally directly affects cold-chain cargo quality and delivery security. According to international shipping media outlet WorldCargo News, all of Evergreen Marine's roughly 58,000 refrigerated containers are now equipped with Internet of Things (IoT) technology, enabling continuous monitoring of container location, temperature, humidity, and equipment operating status. This marks an important step toward full-process visibility in its cold-chain transport management.
In terms of the monitoring mechanism, when the system detects issues such as temperature deviations, unauthorized door openings, or equipment failures, it can trigger alerts so relevant personnel can follow up in a timely manner. This kind of functionality helps operators stay informed about reefer status in transit and improves the timeliness of anomaly detection. However, the actual effectiveness of any response after an abnormal event still depends on the specific situation, response procedures, and follow-up operational coordination. IoT technology provides status information and early-warning capability, but closing the loop still requires coordination between ship and shore, emergency response plans, and cooperation at the destination port.
The report also noted that Evergreen's reefer containers use refrigeration equipment from different suppliers. Most are fitted with units from Carrier Transicold, while a smaller number use Star Cool units from Maersk Container Industry, which are remotely monitored through its Sekstant platform. The coexistence of multiple equipment types and platforms means Evergreen must manage data integration and monitoring standards across different systems, which places corresponding demands on unified operational management.
From equipment monitoring to anomaly alerts, IoT technology provides more status information throughout reefer transportation, helping improve the transparency and controllability of cold-chain logistics. For freight forwarders and cold-chain cargo owners, this type of capability can provide stronger data support for booking, in-transit tracking, and exception communication. However, it should be noted that current public reporting has not disclosed the specific extent to which the system has improved cargo damage rates, operating costs, or transport efficiency. The actual impact will still need to be evaluated through further observation of operational data, exception-handling efficiency, and customer feedback.
