摘　　要：海上施工是海上工程建设面临的重要挑战,作业天数是海上施工重点关注的内容。为解决工程区风浪资料缺乏时作业天数分析的困难,文章将长期海洋站风、浪观测资料分析与数值模拟相结合,提出一种实用的海上施工作业天数分析方法。该方法应用于涂茨海上风电工程施工作业天数分析以及船型选择分析表明,波高变化对风电工程作业天数的影响最为敏感,若要作业天数达到300 d以上,建议选择抵抗风力不小于6级,波高不小于1.5 m,波周期不小于8.0 s的施工船舶。相较于传统的单因素分析,该方法考虑了风、波高、波周期三者的联合作用,计算结果更符合工程实际,对施工前期阶段的船机选型具有指导意义。Offshore construction is an important challenge facing the offshore engineering construction,and the operating days are the key content of offshore construction.In order to solve the difficulty of operating days analysis when wind and wave data are lacking in project area,a practical method of days analysis for offshore construction is proposed by combining wind and wave observation data analysis with numerical simulation.The application of this method to the analysis of construction days and ship type selection of the Tuci offshore wind power project shows that the influence of wave height change on the operating days of the wind power project is the most sensitive.If the operating days are more than 300 days,it is recommended to select a construction vessel with wind resistance of no less than 6,wave height of no less than 1.5 m,and wave period of no less than 8.0 s.Compared with the traditional single factor analysis,the method proposed in this paper considers the combined effect of wind,wave height and wave period,and the calculation results are more in line with the engineering practice,which has guiding significance for the type selection of ship in the early stage of construction.
