LNG码头靠船墩布置

Breasting dolphin design in LNG terminal

LNG码头平面设计中,最为重要的是靠船墩位置的设计。针对常规靠船墩位置的设计是按照规范的系数要求选取的,但较难适应所有LNG船型的靠泊。研究如何提高靠船墩对各种LNG船的靠泊适应性:分析LNG船的仓容分布、储罐类型和外型特点,介绍LNG船靠泊准则,并结合某海外1万~22万m^(3) LNG码头工程论述靠船墩的布置。得出如下结论:合理的靠船墩位置不是关于工作平台对称的,而应适当增加船尾方向的靠船墩与工作平台的距离。

In the design of the LNG terminal,the design of the breasting dolphin location is most important.Generally,the breasting dolphin location is designed based on the coefficient requirement in the relevant standards.But it is not suitable for all LNG vessels.Therefore,the paper researches on the compatibility of breasting dolphins to various LNG vessels.Analyzing the storage capacity,tanker type,and appearance characteristics of the LNG vessel,introducing the berthing guidelines for the LNG vessel,and expounding the arrangement of the breasting dolphin based on an overseas 10,000~220,000 m^(3) LNG vessels project,we conclusde that the suitable breasting dolphin location isn t symmetrical about the working platform and the distance between the working platform and breasting dolphin at stern should be increased properly.
