沿海港口LNG码头选址要素分析

Site selection factors for LNG terminal in coastal port

沿海港口液化天然气(LNG)码头的选址受到综合因素的影响,由于筛选要素过多,且存在相互关联,评价过程中难免存在主观偏差的问题。针对沿海港口的LNG码头选址复杂以及其具独特性的问题,进行LNG码头选址要素分析研究。采用模糊层次分析法,结合提出的5大影响因素共计11项评价指标,构建沿海港口LNG码头选址的综合评价指标体系。结果表明,采用模糊层次分析法,通过多专家对指标因子进行赋值和评分,可以更客观且直观地评价LNG码头选址,为沿海地区LNG码头的选址提供更科学、合理的参考。

The site selection of liquefied natural gas(LNG)terminal in coastal port is influenced by comprehensive factors.Due to the excessive selection of factors and their interrelationships,there is inevitably subjective bias in the evaluation process.In response to the complexity and uniqueness of LNG terminal site selection in coastal port,we conduct an analysis on the factors of LNG terminal site selection.By the fuzzy analytic hierarchy process(FAHP),we combine with the 5 major influencing factors,totaling 11 evaluation indicators proposed to construct a comprehensive evaluation index system for LNG terminal site selection in coastal port.The results show that using FAHP and assigning and scoring indicator factors by multiple experts can objectively and intuitively evaluate the site selection of LNG terminals,which can provide more scientific and reasonable references for the site selection of LNG terminals in coastal area.
