大型LNG船舶系泊条件试验研究

摘要

Based on physical model tests of an open sea LNG receiving terminal, utilizing the domestic advanced equipments and test methods, including an L-type wave generator which is the first and could also absorb secondary reflection waves in China, the combined action of winds, waves and currents on mooring ships are simulated and the response of mooring forces and impact forces of large LNG ships to the three kind loads of winds, waves and currents are analyzed. By optimizing the layout of mooring dolphins and the mooring arrangement, the mooring conditions could meet the LNG ship mooring safety requirements, which provides references for the design and operation of engineering projects.%以某开敞式LNG接收站码头工程为例,通过物理模型,采用国内先进的仪器设备和试验手段,包括国内第一台可吸收式L型造波机等,模拟了风、浪、流对系泊船舶的共同作用,分析探讨了大型LNG船舶系缆力和撞击力对风浪流三种环境荷载不同方向的响应.通过优化系缆墩的布置和系缆方式,达到了LNG船舶安全系泊要求,为工程设计和运营提供了依据.
