This study investigates ice impact through numerical simulation to provide information relevant to offshore structural design. A finite element model was developed to simulate the collision between an ice sheet and a conical structure, with ice velocity as the primary parameter. The calculations were carried out using an explicit dynamics approach, which enables the simulation of time-varying impact forces. The results indicate that higher ice velocities result in greater stress within the ice sheet, generating larger reaction forces on the structure, with the increase following a nonlinear trend. These findings provide quantitative insight into the magnitude of loads that may be transmitted to offshore structures, underscoring the importance of accounting for dynamic ice forces in structural design.en2452-32162025522528Elsevierhttps://creativecommons.org/licenses/by-nc-nd/4.0/explicit dynamicsfinite element analysisice impactoffshore structuresSea iceTechnology::623: Military Engineering and Marine EngineeringNatural Sciences and Mathematics::551: Geology, Hydrology MeteorologyConference Paperhttps://doi.org/10.15480/882.1709610.1016/j.prostr.2026.03.08910.15480/882.17096
