摘　　要：针对一艘10万m3和一艘5万m3的LNG运输船过驳安全问题,分析两船碰垫选型、过驳软管选取、总管与软件连接,采用FLACS对过驳期间安全距离进行计算分析。结果表明,两船匹配良好,具备过驳条件,过驳期间需设置大于225 m的安全距离,安全距离内严禁其他船只进入。整个评估过程充分考虑了LNG深冷易燃的特性和LNG运输船的特点,针对性地降低了过驳中可能出现的风险。In order to ensure the safety for LNG ship to ship （STS） transfer, a 100 000 m3 LNG carrier and a 50 000 m3 LNG carrier were selected to study the selection of fender and transfer hosepipe, connection of the main pipe with hospipe. The 3- dimensional CFD software FLACS was adopted to assess the safe distance during the transfer. The results showed that these two carriers have good compatibility, meet the requirements of STS transfer, the safe distance is not less than 225 m. The characteristics of LNG cryogenic cooling and inflammable were fully considered so as to reduce the possible risks during STS transfer of LNG.
