... full-scale experiments on towing non-tabular icebergs of various sizes were conducted in open water conditions. After further processing, 39 pairs of values "Towing force - Iceberg speed" in stationary towing regime were analyzed, with known geometric parameters of the iceberg above-water part. Based...

... transits demonstrated good results in terms of predicting general speed trends during the transits. Furthermore, we have identified two challenges in applying a fully connected NN to speed regime modelling: data quality and accessibility. These challenges are discussed and techniques to minimize them...
