Numerical Investigation of Global Ice Loads of Maneuvering Captive Motion in Ice Floe Fields
Journal of Marine Science and Engineering, 2023 During escort and convoy operations, icebreakers are often required to maneuver to open up channels or adjust routes due to the prevalence of ice floe conditions in Arctic routes. This study aimed to investigate the global ice load characteristics of the
