Maersk upgrades reefer container fleet connectivity

AP Moller – Maersk is around one-third into its programme to replace internet-of-things (IoT) devices across its reefer vessel fleet to improve remote monitoring of cargo condition and performance of containers.

Once the roll-out is complete, the upgrade will "standardise devices and deliver a more consistent customer experience," said Maersk, adding that it had retrofitted IoT devices on around 30% of the reefer fleet by the start of July 2026.

The Copenhagen, Denmark-headquartered operator and owner is installing digital connectivity devices aboard 450 ships to facilitate smarter cargo tracking and management solutions in the future.

It aims to install new devices on all reefers on vessels in the Maersk fleet in the coming years.

“As real-time access and data availability grow increasingly vital for our cold chain customers, the deployment of our next‑generation IoT devices will provide them with a much more reliable data flow throughout the container journey,” said Maersk head of reefer cargo, Bruce Marshall.
