Interpolation Analysis of Shipborne Hydrographic Survey Data Applied to the Discussion of Safe Navigation of Vessels -- Taking Zhoushan Tiaozhoumen Channel as an Example

The development of Ningbo-Zhoushan Port requires the enhancement of navigation capacity of Tiaozhoumen Channel. However, the narrow section of the channel has strong and turbulent tidal currents, which poses great difficulties for pilots. Existing data is too simple to guide pilots in safe ship handling. Through shipborne hydrographic survey, the complex flow characteristics are displayed. Ningbo Dagang Pilotage Co., Ltd. hopes to display the flow field situation during the rising and falling tide periods, guide pilots to prepare for flow pressure difference angle, and ensure safe navigation. Interpolation analysis of shipborne hydrographic survey data is applied to display the regularities and characteristics of flow fields at different tide periods. The interpolation results show that the tide period conversion displayed is basically consistent with the tide period of Zhenhai Tide Station, which is referred by pilots in Ningbo Dagang Pilotage Co., Ltd.. The spatial distribution of the current is roughly consistent with the results calculated by pilots based on ship navigation data, which can also reasonably explain the pilot's many years of operating experience in the narrow section of Tiaozhoumen Channel. This indicates that using interpolation analysis of shipborne hydrographic survey data to calculate the flow distribution of the channel water area has a certain rationality. However, the actual flow field is affected by factors such as terrain and weather, and these factors need to be comprehensively considered in prediction to improve accuracy. This study provides important references for flow field analysis in the channel water area, but further research and verification of other related data are still needed to fully understand the changes and predictions of the flow field.
