海上风电工程毗邻水域通航安全评价

Evaluation on navigation safety in adjacent waters of offshore wind power projects

为研究海上风电工程近岸化、规模化和集群化效应对毗邻水域通航安全的影响,将决策试验和评价实验室(decision-making trial and evaluation laboratory,DEMATEL)方法与网络分析法(analytic network process,ANP)结合对其通航安全进行评价。选取水文气象、交通环境、通航船舶和安全保障等4个方面的影响因素建立评价指标体系,通过DEMATEL方法计算指标间综合影响矩阵,通过ANP梳理指标网络结构,并运用模糊重心法对系统进行定性评价。实例研究证明,所提出的模型及方法能够较客观地评价海上风电工程毗邻水域通航安全水平。该方法可确定对通航安全影响较大的指标,为相关主管部门提供参考。

In order to study the influence of nearshore,scale and clustering effect of offshore wind power projects on navigation safety in adjacent waters,the decision-making trial and evaluation laboratory(DEMATEL)method are combined with the analytic network process(ANP)to evaluate the navigation safety.The evaluation index system is established by selecting the influencing factors from four aspects:the hydrometeorology,traffic environment,navigable ships and safety guarantee.The comprehensive influence matrix between indices is calculated by DEMATEL method,the index network structure is sorted out by ANP,and the system is qualitatively evaluated by the fuzzy center of gravity method.Example studies prove that,the proposed model and method can objectively evaluate the navigation safety level in adjacent waters of offshore wind power projects.This method can determine the indices with greater impact on navigation safety,which can provide reference for the relevant competent departments.
