最近的飓风事件暴露了石化设施容易受到洪水或风暴潮造成的严重交通网络中断的影响。网络中断可能会导致连锁影响或放大由于应急响应延迟和现场访问受限而对石化基础设施造成的破坏的后果。这项研究提出了一个基于情景的框架，以评估风暴潮事件期间应急人员和工作人员对石化设施的可达性。首先，该框架将风暴潮模拟与地上储罐脆弱性模型结合起来，以确定可能发生自然灾害触发的技术(NatECH)事件的位置。然后，风暴潮模型与桥梁脆弱性模型和地理系统分析相结合，以评估桥梁故障和道路淹没等网络中断的可能性。最后，进行了概率网络分析，以评估应急人员和设施工作人员对NAECH站点随时间演变的可达性。作为概念验证，该框架被应用于一个案例研究领域。案例研究区域的结果表明，拟议的框架是一个强大的工具，可以量化潜在的国家自然和环境卫生事件的可及性，促进缓解和紧急活动，并改进风暴期间和之后对关键资源和人员的管理。
Recent hurricane events have exposed the susceptibility of petrochemical facilities to severe transportation network disruptions due to flooding or storm surge. Network disruptions can result in cascading impacts or amplify the consequences of damage to petrochemical infrastructure due to delayed emergency response and limited access to the site. This study presents a scenario-based framework to assess the accessibility of petrochemical facilities by emergency responders and workers during storm surge events. First, the framework couples storm surge modeling with aboveground storage tank fragility models to determine the locations where natural hazard-triggered technological (NaTech) events could occur. Then, storm surge modeling is coupled with bridge fragility models and geographic system analysis to evaluate the potential for network disruptions such as bridge failures and road inundations. Finally, probabilistic network analyses are performed to evaluate the time-evolving accessibility of NaTech sites to emergency responders and facility workers. As a proof of concept, the framework is applied to a case study area. Results for the case study area demonstrate that the proposed framework is a powerful tool to quantify the accessibility of potential NaTech events, facilitate mitigation and emergency activities, and improve the management of critical resources and personnel during and after a storm.
