Digital Twins in Route Optimization and Planning

What is a Digital Twin? 

A Digital Twin is a virtual representation of a physical object, process, or system that mirrors its real-world counterpart in real-time. By integrating data from sensors, IoT devices, and other sources, Digital Twins allow for accurate modeling, simulation, and analysis. This technology is widely used in various industries as well as in container shipping to enhance decision-making, predict outcomes, and optimize performance.  

Digital Twin vs. Smart Ship 

While both Digital Twins and smart ships leverage advanced technologies, they each serve distinct purposes.

A smart ship integrates digital systems onboard to improve operational efficiency, safety, and environmental performance. In contrast, a Digital Twin exists as a separate virtual replica of the ship, enabling real-time simulation and analysis of various scenarios without impacting actual operations.

For example, a smart ship might use AI to optimize energy consumption during a voyage, whereas a Digital Twin could simulate the impact of alternate routes or maintenance schedules on fleet-wide efficiency. 

While we're not yet using smart ships, we rely on smart containers and equipped more than 85% of our entire container fleet with IoT devices already. That enables you, as our customer, to see the real-time location data of you cargo at every leg of the multi-modal transport.

Digital Twins in the supply chain 

Digital Twins are revolutionizing supply chain management by providing real-time visibility and predictive insights. One example is their use in warehousing. A Digital Twin of a warehouse can be used to monitor inventory levels, predict demand surges, and optimize storage layouts, reducing operational costs and delays. Similarly, in maritime logistics, Digital Twins can simulate port activities to minimize congestion and improve cargo handling efficiency.

The following examples illustrate how this technology is being applied across different areas of logistics such as route optimization and port operations: 

1. Route optimization with Digital Twins

Route optimization is one of the most impactful applications of Digital Twin technology in shipping. By simulating various routing scenarios, Digital Twins can identify the most efficient paths for vessels based on factors such as weather conditions, sea currents, and port availability. For instance, a Digital Twin of a shipping lane might analyze historical and real-time data to suggest a route that avoids severe weather while reducing fuel consumption. It can also take real-time events such as political tractions into account. This not only improves punctuality but also supports sustainability goals by minimizing carbon emissions. 

The Port of Rotterdam uses Digital Twin technology to optimize vessel routes by combining real-time weather data, tidal patterns, and historical ship movement data, ensuring safe and efficient navigation.

2. Real-time fleet management

Fleet managers can leverage Digital Twins to maintain a comprehensive, real-time overview of their vessels. By aggregating data from individual Digital Twins, fleet operators can monitor performance metrics, identify maintenance needs, and allocate resources effectively. For example, if a ship's engine efficiency decreases, its Digital Twin can flag the issue well in advance before it becomes an actual problem, allowing proactive maintenance before it escalates into costly downtime. 

Maersk, for example, has implemented Digital Twin solutions that allow their operations team to track fuel efficiency and predict maintenance needs, avoiding unexpected downtime and further optimizing fleet utilization and fuel consumption.

3. Mitigating congestion with Digital Twins

Congestion at ports and shipping lanes remains a significant challenge for global logistics. Digital Twins can simulate port operations, identifying bottlenecks and proposing strategies to reduce congestion. For instance, a Digital Twin of a busy terminal might suggest rescheduling arrivals to avoid overlap, improving turnaround times and reducing idling emissions.  

A perfect example for the congestion mitigation is the Singapore Maritime Port Authority. They use Digital Twin technology to forecast port congestion and optimize vessel schedules. By rescheduling arrivals and departures to avoid overlaps, the system improves turnaround times, reduces idling times and emissions, and enhances the overall operational efficiency. 

Future Developments 

The future of Digital Twins in maritime operations looks promising. Advancements in AI and machine learning are set to enhance their predictive capabilities, enabling more precise decision-making. Integration with blockchain  improves data security and transparency across the entire supply chain.  

Furthermore, as 5G connectivity expands, the real-time data exchange between Digital Twins and their physical counterparts will become faster and more reliable, unlocking new possibilities for use cases like remote operations and autonomous shipping but especially will affect established use cases and will make these even more available.

Digital Twins are transforming route optimization and planning in the shipping industry by enhancing efficiency, reducing costs, and enabling data-driven decision-making. As technology evolves, its applications in real-time fleet management and congestion mitigation will continue to grow, driving innovation in the global supply chain. As current examples show us, in only a couple of years investing in Digital Twin technology will no longer be optional but a strategic necessity for staying competitive in an increasingly complex and interconnected world.
