When a ship navigates through ice areas, structural and vibration responses will be generated on the ship hull under the collision of sea ices. The magnitude of the response is highly correlated with the factors such as sea ice conditions, ship speed, structural stiffness, and measurement position. To be distinguished from the localized structural vibration, the global motion and vibration response of the ship can be referred to as ship bumping, which has a large impact on the functionality of the shipboard equipment, easily resulting in various issues such as lessening of the fastenings. The ship bumping in ice has been examined based on the data measured by the distributed accelerometers on board the icebreaker Xuelong II during the voyage in the Antarctic ice area. The events of ship bumping in ice are identified by the neural network method based on the time-frequency analysis. The ship bumping signals are separated by the frequency spectral analysis to extract the key parameters of the ship bumping in ice, such as the acceleration amplitude, pulse width, and the occurring frequency. The identification and analysis methods are finally established. On this basis, the data of ship bumping in ice of various typical scenarios are analyzed to investigate the influence of sea-ice environment, ship speed, and measurement position on the key parameters of the ship bumping. The requirements of the capability of shipboard equipment to withstand bumping under different sea-ice conditions are then summarized to provide references for the selection of polar ship equipment.
