Digitalization is a web of interconnected technologies enabling each other to improve efficiency, reduce risk, and enhance the safety of marine fleets and offshore asset operations. Digital twins, also known as virtual assets, will serve as a vital centerpiece of the broader digitalization puzzle.

?

A digital twin mirrors a physical asset and its environment using a virtual representation continuously updated by sensors, providing real-world data in real-time. Twins can range in scope to include individual machinery components, systems or systems of systems, such as an entire vessel or offshore asset. The

digital twin analyzes real-world data to provide simulation-driven decision support for the system.

?

The accuracy, complexity and sophistication of a digital twin can vary depending on its targeted outcome. For example, an offshore asset could use a twin for monitoring structural health and improving remaining life. An ultra-large container carrier could employ a digital twin to provide insights on day-to-day operations, such as speed or course changes to optimize fuel consumption and emissions.

Looking Into the Future

The growth of connectivity infrastructure, sensor capabilities, cloud and edge computing power and AI systems are combining to drive the evolution of digital twins. As digital twins become more pervasive and reliable, they will play an ever-increasing role in maritime operations. The more variables a digital twin can account for, enabled by the various digitalization areas, the clearer the picture it will have of the real-world vessel or offshore asset.

?

Initially, real-time monitoring will support human-level decision making, such as voyage optimization, fuel management, maintenance timing and decisions regarding remaining life. In time, digital twin systems are expected to reach self-learning and self-awareness benchmarks that will serve as essential foundations for fully autonomous functions.

?

As digital twin technology advances alongside improvements in connectivity, computational power and machine learning, twins will be capable of proactively seeking relevant data from potential inputs, such as sensors, drones or video systems. The twin will decide which inputs offer the most useful data for a given situation and continuously update its own model. An advanced twin could also gain enough awareness to model its own environment and account for possible outside variables during decision-making.

?

Digital twins will continuously find ways to improve decision-making capabilities, progressively gaining self-awareness. Key steps will include self-replication for multi-physics, multi-data model simulations and communicating with other digital twins and Internet of Things (IoT) systems to gather even more data.

?

As digital twin technology advances and achieves elements of cognition, such as perception, comprehension, memory, reasoning, prediction, reaction and problem-solving, it has the potential to enable fully autonomous functions with zero human input — making optimal data-based decisions for the asset in various situations.

?

A vessel-based digital twin could eventually connect with twins across industries to integrate with cargo and port operations, transportation logistics and commercial operations to enable more efficient global commerce. As owners become more open to allowing their twins to communicate with other twins, they could then begin to work together as a single interconnected entity, like a swarm, with each one subtly influencing others to predict behavior for the entire swarm and optimize the whole system.
