As the coastal liquid chemical port areas and petrochemical industrial bases develop rapidly,the requirements for safety and environmental risk prevention in port zones are increasing.To make full use of existing infrastructure and ensure emergency oil spill response in the port area,taking the bucket-type structure foundation of the east breakwater in Xuwei port area of Lianyungang Port as an example,the spatial characteristics and load-bearing capacity of the buckets are analyzed.Partial functional modifications are made to the existing bucket-type structure,transforming it into an emergency pool within the port area.This forms a zonal emergency pool system within the port,which is used to collect and store oil and various wastewater that may leak along the public utility corridor in emergencies.This helps reduce pollution and ecological damage to the marine environment,and meets the accident wastewater interception capacity requirements stipulated in the environmental assessment.Compared with building new emergency pools,this approach can save 78.5% of construction investment,shorten the construction period by 66.7%,and save 100% of sea area usage.Considering factors such as construction investment,construction period,safety and environmental protection,maintenance costs,and rapid response,this solution is feasible.It explores an operational management model for port infrastructure that serves both routine and emergency needs,providing an innovative solution for similar coastal industrial port areas to address safety and environmental risk emergency prevention and control.
