Ocean Network Express (ONE) is expanding its digital visibility capabilities for refrigerated cargo through CONTAINER+, its reefer monitoring solution that provides near-real-time information through a centralized dashboard. ONE highlighted the solution in a September 2026 update, positioning it as a way for shippers to monitor temperature-sensitive cargo across both ocean and inland transportation.
 

🌡️ Beyond tracking location

For refrigerated cargo, knowing where a container is only tells part of the story.

Fresh produce, seafood, pharmaceuticals and other temperature-sensitive products can be affected by changes in temperature, humidity, atmosphere or power status. CONTAINER+ brings these different data points together so users can monitor the location and condition of the cargo from a single dashboard.

The platform provides visibility into:

• Container location and route

• Supply and return air temperature

• Ambient temperature

• Humidity

• Reefer power status

• O₂ and CO₂ levels for controlled-atmosphere shipments

• USDA cold-treatment data where applicable
   

🚢 Ocean and inland visibility
 

A key aspect of the solution is that monitoring extends across ocean and inland transportation, rather than stopping once a container leaves the terminal.

ONE says CONTAINER+ data is updated hourly when connectivity is available, allowing customers to follow the journey and monitor changing cargo conditions. Users can also download data for further analysis and operational or compliance purposes.

This is particularly relevant for cold-chain shipments, where a temperature problem discovered at destination may be too late to address.
 

⚡ Moving from reactive to proactive logistics

The bigger value is the ability to identify potential issues earlier.

If temperature, humidity or reefer power conditions begin moving outside expected parameters, logistics teams can investigate and respond before the situation develops into cargo damage or spoilage.

ONE has previously described its reefer telematics strategy as a way to improve active monitoring, proactive decision-making and customer visibility across refrigerated shipments.

📊 Why this matters for the cold chain
 

The development reflects a broader change in freight visibility.

Traditional tracking focuses primarily on:

Where is my shipment?

Connected reefer technology adds:

What temperature is it at?
Is the equipment powered?
What are the humidity and atmospheric conditions?
Is the cargo still within acceptable parameters?

That makes visibility increasingly multidimensional.

For cold-chain operators, the combination of location, equipment and condition data can support better exception management, cargo-quality monitoring, customs documentation and supply-chain planning. ONE also highlights the availability of detailed cargo-condition information, including cold-treatment data, for customs clearance when requested.

🔮 The bigger trend

ONE's CONTAINER+ expansion shows how connected containers are changing the definition of freight visibility.

Location tells you where the cargo is. Condition data tells you how the cargo is doing.

As more refrigerated containers become digitally connected, visibility is moving from simple tracking toward continuous cargo-condition intelligence, helping logistics teams identify risks earlier and make decisions before problems become losses.

For temperature-sensitive freight, the future of visibility isn't just knowing where the container is. It's knowing what's happening inside it.
