With the accidents of offshore structures occurring frequently, the significance of risk assessment in the process of transportation, installation and operation is increasing. In this paper, the risk assessment of offshore wind turbine in transportation and installation is presented. Firstly, the main task profiles are identified according to the concrete operation process, the components and risk factors related to the assessment. Secondly, FTA of hoisting aboard and FMEA of installation process are established based on RELEX Studio 2011. The failure modes of task profiles are analyzed and coefficients are assigned according to the principle of As Low As Reasonably Practicable. Finally, using Risk Priority Number method to evaluate their severity rank, and some recommended operations and management measures are given. Risk assessment is applied in offshore wind turbine transportation in this paper and the work has great significance to the evaluation and future design of offshore structures.
