However, such methods have difficulties capturing the entire complexity of ship–ice interaction process due to the incomplete understanding of the underlying physical phenomena. Therefore, data-driven approaches have recently gained increased attention in this context. Hence, this paper proposes a concept of a first machine learning-based simulator of ship speed profile in a complex ice field. The developed approach suggests using supervised machine learning to trace a function mapping several ship and ice parameters to the ship acceleration/deceleration between the two adjacent points along the route. The simulator is trained and tested on a dataset obtained from the full-scale tests of an icebreaking ship. The results show high accuracy of the developed method, with an average error of the simulated ship speed against the measured one ranging from 2.6% to 9.4%.en1744-530220209974980Taylor and Francishttps://creativecommons.org/licenses/by-nc-nd/4.0/Artificial neural networkmachine learningship ice transit simulationsship resistance in iceship speed profile in iceMLE@TUHHTechnikJournal Article10.15480/882.305410.1080/17445302.2019.169707510.15480/882.3054Journal Article
