摘要
分析国内外相关文献中有关船舶下沉量和富余水深的影响因素,结合宁波港附近水域的通航环境特点,建立适合本工程海域LNG船舶航行所需安全水深的计算模型;利用Matlab软件对几种下沉量计算公式进行对比分析,确定能够充分保证航行安全的下沉量计算公式。根据建立的安全水深计算模型,提出LNG船舶在不同航速情况下所需安全水深建议值。
The calculation model of the safe water depth of LNG ship navigation is established by analyzing the impact factors of the ship squat and the under keel clearance in the domestic and foreign references as well as the navigational environment characteristics of Ningbo port and its nearby waters. A Matlab program is used to analyze several kinds of calculating formula of squat. Combining with the characteristics of LNG ship design, the calculation formula for the squat of navigation is determined. According to the proposed calculation model of safe water depth, the safety depth of LNG ship at different speed is determined.
