GPS Tracking Systems for Offshore Reefer Container Logistics

Offshore reefer containers equipped with refrigeration systems to maintain optimal temperature and humidity during transportation are crucial for the safe and timely delivery of perishable goods in today’s globalised economy. 

However, tracking and managing these containers in the vast ocean is not a straightforward process. This is where GPS tracking systems come into play, revolutionising offshore reefer container logistics.

What are GPS tracking systems?

GPS, or Global Positioning System, is a satellite-based navigation system that tracks and monitors locations in real-time. GPS tracking systems use satellites to locate a GPS-equipped object or vehicle. In logistics and transportation, these systems can be exploited to provide data for route optimisation, security, and operational efficiency.

In practice, GPS tracking systems can be classified into two types: active and passive. Active GPS tracking systems transmit data in real-time or at regular intervals, allowing continuous monitoring and control of the reefer containers. 

Passive GPS tracking systems store data in an internal memory and transmit it only when requested or when within range of a receiver, allowing periodic checking and analysis of the reefer containers.

Types of GPS tracking systems used in logistics

In general, GPS tracking systems offer numerous benefits, such as improved fleet management, enhanced security, and better customer service. Let’s briefly explore some of the key types of GPS tracking technologies commonly used:

  • Real-time tracking: Real-time GPS tracking systems provide continuous location updates, enabling logistics operators to monitor the movement of their assets in real-time. This allows for proactive decision-making and prompt response to any deviations from planned routes or schedules.
  • Geo-fencing: Geo-fencing technology allows logistics companies to define virtual boundaries or geographically-restricted areas. When a GPS-equipped asset crosses these pre-defined boundaries, the system triggers alerts, enabling immediate action to be taken.
  • Temperature monitoring GPS: For perishable goods transported in reefer containers, temperature monitoring is crucial. GPS tracking systems can integrate with temperature sensors within containers, providing real-time temperature data. This ensures that the cargo remains within the required temperature range, minimising the risk of spoilage.

Benefits of using GPS tracking systems in general logistics

Cargo monitoring: Reefer tracking systems provide full cold chain visibility from multiple devices. If the reefer gets too warm, shipment owners can get mobile alerts. With GPS equipment location and status information, reefer fleet utilisation, dwell or cycle times, and repositioning costs are reduced.

Increase operational efficiency: Reefer tracking systems monitor cold chain temperatures automatically. By centralising and automating the temperature logbook, manual records are eliminated, thereby eliminating operational inefficiencies. 

Faster response in case of trouble: Reaction time is important in refrigerated shipping. Reefer tracking systems allow fast response times in case of any technical challenges, like drastic temperature changes. This enables crews to react appropriately to save the cargo.  

Enables data-driven decision-making: With the data from reefer tracking systems, freight providers have sufficient information to optimise routes or overhead costs. 

Enhanced cargo security: Reefer tracking systems can help deter and help prevent cargo theft, tampering, and fraud. Some systems have unique mechanisms for remotely detecting threats to ensure optimal security.

Minimise temperature-related spoilage: Most temperature-related spoilage is caused by reefer unit failure. However, tracking systems can send automated alerts to keep reefer units in top condition. Reefer tracking systems’ extensive temperature data loggers can provide actionable container temperature data, and If integrated with GPS location tracking, they can determine temperature variations and periods of variation to reduce cargo spoilage.
