LNG船舶夜间通航安全性的仿真研究

Simulation Study on Night Navigation Safety of LNG Ship

为确保大型LNG船舶夜间进出港及靠离泊安全,提高北海LNG船舶夜间通航能力,本文构建综合评判模型和夜航动力学模型对北海LNG船舶夜航通航进行安全进行评估,然后提出靠离泊方案和限制条件,最后进行了船舶模拟仿真试验。根据对夜间通航环境的评估结果,北海LNG码头具有良好的本质安全性,试验表明广西北海港铁山港区LNG码头26.6万m³ LNG船舶、21.5万m³ LNG船舶、17.5万m³ LNG船舶在限定条件下,夜间航道航行、满载靠泊、压载离泊均能安全完成。

In order to ensure the safety of large LNG ships entering and leaving ports at night and berth and improve the night navigation capacity of LNG ships in the Beihai port, this paper constructs a comprehensive evaluation model and a night navigation dynamics model to evaluate the night navigation safety of LNG ships in the North Sea, then puts forward berth and berth schemes and restrictions, and finally conducts ship simulation tests. According to the assessment results of the night navigation environment, the North Sea LNG terminal has good intrinsic safety. Tests show that 266,000 m3 LNG ships, 215,000 m3 LNG ships, and 175,000 m3 LNG ships at the LNG terminal in Tieshan Port Area of Beihai Port in Guangxi can safely complete night navigation, full load berthing, and ballast deberthing under limited conditions.
