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.

Mathematical modelling and simulation of AMV is a necessary part of the digital-twin contact development. This course aims to provide the student with the skills and knowledge required to model, simulate and then analyse the complex non-linear behaviour of AMV using MATLAB/Simulink.

You'll explore the entire process of structuring a risk problem, modelling it, supporting and communicating recommendations, both theoretically and in practice. Risk management is linked with decision analysis in so far as we explore decision-making under uncertainty and it has links with quantitative business analysis as we explore the use of statistics in understanding risk. However, the topic has some unique attributes such as risk communication and the role that experts play in risk assessment.
