中石化广西液化天然气项目海洋自然灾害风险评估

Evaluation of marine natural disaster risk in Sinopec Guangxi liquefied natural gas project

  • 摘要: 中石化广西液化天然气(LNG)项目是广西沿海地区引进的国家重点清洁能源工程,其抵御海洋自然灾害的能力直接影响广西地区的经济发展速度。本研究结合LNG项目海岸防御工程的设计标准及现状,进行风暴潮、海浪自然灾害的设计标准及设计参数的风险分析,将推算得到的防御工程应达到的理论顶高程与实测高程进行对比,评估各段抵御海洋自然灾害的能力。研究发现无论是设计高潮位还是考虑海平面上升之后的极端高潮位均大于工程设计值;东南偏南(SSE)向波高的评估结果均大于设计值,其他方向波高的评估值与设计值差别不大;东南、西南段海岸防御工程的实测最低高程要低于评估高程,其他段具有一定的防御海洋自然灾害能力。

     

    Abstract: Sinopec Guangxi liquefied natural gas (LNG) project is the important national clean energy program introduced by Guangxi coastal region, and its defense capacity of marine natural disaster (MND) could directly influence the Guangxi economic development.This study investigated the design standard and status quo of LNG coastal defense project (CDP), analyzed the design standard and parameter of storm surge and ocean wave, and evaluated the MND defense capacity of each section by comparing the right theoretical CDP elevations with the measured ones.Results showed that evaluation results of both design high tide level and extreme high tide level in consideration of sea level exceeded the preliminary design value.Evaluation results of wave height in south by southeast (SSE) direction were greater than the designed values, and in other directions they were fairly equivalence.The measured minimum elevation of CDP in southeastern and southwestern section was lower than the evaluation value, which carried some risk, and the CDP in other sections could defense the MND to some extent.
