Maersk Line has ordered 100 of 200 reefers that will utilise Carrier Transicold's NaturaLINE natural-refrigerant based system.
The cooling system uses carbon dioxide drawn from outdoor air to help refrigerate the containers, which reduces the impact on global warming as compared with traditional systems that use hydrofluorocarbon refrigerants.
With the system being equipped on the 40 ft high cube containers, delivery of the 100 units is scheduled for the first quarter of this year.
Maersk intends to utilise the reefer units on closed-loop trades between Europe and the Americas and is training crew and land-based employees to be able to handle and service the new containers.
“To meet our sustainability goals and stay ahead of the new EU legislation, Maersk Line is keen to carefully evaluate all alternatives to the current synthetic refrigerants,” said Maersk Line head of global equipment Ingrid Uppelschoten-Snelderwaard.
“The NaturaLINE system is an advanced technology with interesting potential for reefers. We chose it after laboratory testing of the unit’s performance with perishable and frozen commodities and look forward to gaining further operational experience with the system.”
The new reefers joined the 270,000 containers owned by Maersk Line and will have built-in remote container management technology, which converts each box into a digitally linked device for cargo monitoring purposes across the fleet.
The so-called block chain solution will allow Maersk and IBM to manage and monitor the documentation of containers shipped across the globe from one end of the supply chain to the other and share this data with trading partners.
