Digitalisation has become an essential part of the maritime industry, ultimately steered at making the sector more innovative and productive, particularly for Autonomous Marine Vehicles (AMVs).

A digital twin is a dynamic digital representation of an AMV, capable of replicating significant aspects of autonomy, including dynamics, control, guidance, and navigation. The idea is to create a virtual version of the AMV to achieve a realistic, digital simulation of the system utilising the state-of-the-art physical models.

The digital version of the system can be then utilised to mirror the behaviour of the real-world twin using the sensor updates and historical data. The digital twin can be employed to perform complex scenarios simulation to mitigate loss or performance decay by recommending changes in the use of the AMV and increases the success-probability of the mission.
