The maritime industry is essential to the world economy, as more than 90% of world trade is carried by the sea. Despite the dimensions of the maritime industry, it has not yet developed as much in the field of informatics as some other industries. The diploma thesis presents an exploratory data analysis of operational data from the port of Bordeaux, as well as the methodology and results of building a model for cargo vessels turnaround time predictions. Turnaround times are used to plan the allocation of resources and space. The model is based on the open-source CatBoost machine learning library. The predictive model is validated using a cross-validation method on 11 years of historical data and two months of live data. The mean absolute error MAE on the historical data is 13.66 hours and 14.12 hours on live data. The model outperforms the currently used system in the port, where the MAE is 41.48 hours.
