ATHENA Research Center presented their paper titled “Time Series Analysis for Digital Twins in Green Shipping”, by Lazaros Avgeridis, Konstantinos Lentzos, Dimitrios Skoutas and Ioannis Emiris, at the 8th International Symposium and Maritime Exhibition on Ship Operations, Management and Economics (SOME 2023). The Symposium is a bi-annual event that has been taking place for over 15 years. This year it took place in Athens at the Eugenides Foundation Conference Center Auditorium, on Tuesday 7th and Wednesday 8th of March. The paper was presented by Lazaros Avgeridis as part of Session No. 3: “Digital Twins, Performance Optimization”. The presentation started with a brief introduction to Digital Twins (DTs) and, in this context, the need to process and analyse time series data from the available sensors on the ship to extract meaningful insights and drive decision-making and predictions. An overview of state-of-the-art techniques for anomaly detection in time series was then presented, as well as preliminary experimental results from applying such methods on real-world vessel data. The presentation was followed by questions and a discussion with other attendees. Of particular interest was how to distinguish between real anomalies and potential false positives, as well as on other data cleaning techniques that could be applied.
