Reefer container monitoring on vessels refers to the continuous recording and control of temperature, humidity, CO₂ levels and other climate parameters within refrigerated containers during sea transit. Onboard sensors and data loggers capture all relevant readings; the vessel's crew or automated systems intervene immediately whenever parameters drift outside the set range. For freight forwarders and shippers, the unbroken data record is essential: it proves cold chain compliance to authorities and consignees and forms the primary basis for defending against cargo claims. Unlike land-side monitoring, shipboard reefer supervision typically runs through the vessel's own cargo control system, leaving the shipper with no direct intervention capability during the voyage.
