The maritime industry relies on Automatic Identification System (AIS) data, which provides infor-mation on movement of vessels at sea. Determining meaningful and useful insights from this data is a challenge. The complexity and volume of the information make it difficult for traditional methods to provide in-depth insights and explanations. This paper presents an innovative Explainable AI (XAI) approach to explore maritime movement information using AIS data by leveraging high dimensional Density-Based Spatial Clustering of Applications with Noise (Hi-DBSCAN) algorithm and SHAP (SHapley Additive exPlanations) values in a novel way. Through ex-periments using real AIS datasets, the study reveals the efficacy of SHAP in determining the influence of AIS features on cluster formation. Results from two distinct AIS datasets demonstrate the efficacy of this method. This approach effectively unravels the ‘black box’ nature of clustering, providing maritime stakeholders with a clearer understanding of vessel behaviour patterns. For instance, in one dataset, the course of the vessel was identified as the most significant feature impacting clustering outcomes. Furthermore, the study explores SHAP's potential for anomaly detection by identifying data points with inconsistent feature influences. This study demonstrates that integrating Hi-DBSCAN clustering with SHAP analysis offers a transparent and interpretable method for under-standing vessel behaviour patterns from maritime movement information and extraction of meaningful insights. This framework provides maritime stakeholders with insights beyond traditional pattern recognition, with trans-parency and explainability, allowing for a deeper understanding and more informed and data-driven decisions in maritime operations.Data Analytics, DBSCAN, Explainable AI, AIS, SHAP.
