超规范环境条件的海口新海港区口门航道通航宽度计算

Calculation of Navigable Width of Port Channel in Haikou Xinhai Port Area under Super-standard Environment

针对超规范环境条件下的船舶通航宽度问题,综合考虑船舶自身操作特性、船舶航行基本尺度所需通航宽度、风致漂移量、流致漂移量等因素,采用基于风流漂移的船舶通航宽度计算模型计算代表船型所需双向通航宽度。在风流漂移模型中选取不同流速、风速情况下,船舶空载、满载等不同组合时风流漂移模型计算的航道宽度与《海港总体设计规范》计算的通航宽度进行对比,验证模型的适用性和准确性,计算超规范环境条件的航道宽度,根据计算模型分析不同风流条件组合下船舶的航速限制条件。

In order to calculate the navigation channel width of ships under super-standard environmental conditions, comprehensive consideration was given to the ship’s own operational characteristics, navigation width, wind-induced drift, flow-induced drift and other influencing factors, and the navigation width calculation based on wind drift was adopted. The model calculation represents the two-way navigation width required for the ship type. In the wind drift model, when different flow rates and wind speeds were selected, the navigation channel width calculated by the wind drift model was compared with the calculated navigation width of the Harbour Design Code to verify the applicability of the model. The width of the channel in the super-standard environment was calculated to analyze the speed limit conditions of the ship under different airflow conditions.
