摘　　要：为有效推进绿色低碳发展,且随着LNG(液化天然气)船型发展呈现出小型化返加注的新需求,改造已建大型LNG码头,以适应新增小型LNG加注船的靠泊逐渐成为一种趋势。本文基于既有大型蝶形布置LNG码头提出了一种新增靠泊簇桩系统的改造方式,利用空间模型对该结构进行模拟,分析其受力和系统位移,并验证大型LNG船系泊时对该系统的影响,最终提出一套针对该结构的设计流程。改造后的码头可靠泊返装多种小型LNG加注船型或运输船,适应性强、安全可靠、耐久性优越,且改造工期短、投资省,具有较好的应用价值和推广前景。With the development of liquefied natural gas(LNG)ship types,there is a new demand for small-scale refueling.To effectively promote green and low-carbon development,it is a trend to retrofit the existing large LNG wharf to adapt to the berthing of new small LNG bunker vessels.This article proposes a retrofit method for adding a berthing pile cluster system based on the existing large butterfly-arranged LNG terminal.The space model is used to simulate the structure,analyze its force and system displacement,and verify the influence of large mooring LNG ships on the system.Finally,the article proposes a set of design processes for the structure.The wharf after retrofit can berth and refuel a variety of small LNG refueling ships or carriers,with better adaptability,safety and reliability,superior durability,short retrofit period,and low investment,which has good application value and broad promotion prospects.
