摘要
沿海进口液化天然气(LNG)目前在我国天然气供应体系中发挥了非常重要的作用。通过分析我国沿海及分区域LNG码头建设现状、到港LNG船型、船舶密度和码头利用现状,得出结论:受消费需求不均衡、配套设施能力有限等多方面因素影响,部分LNG码头能力尚未充分释放,局部地区LNG码头淡旺季利用不均衡。根据各区域到港LNG船型结构、船舶密度的分布规律,分淡、旺季对各区域LNG泊位利用率进行测算,提出了沿海分区域平均泊位利用率和局部地区高峰季泊位利用率参数。在此基础上,结合LNG码头运营和船舶监管特点,指出沿海LNG码头运营存在的问题并提出建议。研究结论可为区域LNG码头相关港口规划和设计提供参考。
The import of LNG plays an important role in China's natural gas supply system.Based on the analysis of the status of berth construction,the type of LNG vessel,ship density and berth utilization in China's coastal and sub-regional liquefied natural gas(LNG),this paper puts forward the conclusions that most LNG berth capacity in coastal areas of China has not been fully released and the utilization of LNG berths in local areas is not balanced in off-peak season due to various factors such as unbalanced consumption demand and inadequate capacity of supporting facilities.Furthermore,according to the distribution law of LNG ship structure and ship density in each region,the utilization rate of LNG berths is calculated in light and peak seasons,and the average utilization rate of berths in coastal areas and the parameters of the utilization rate of berths with the highest peak month in some areas are put forward.On this basis,combined with the characteristics of LNG berths operation and ship supervision,the problems existing in the operation of LNG berths in coastal areas are pointed out and corresponding suggestions are put forward.The research conclusions can provide reference for regional LNG port planning and design.
