IEC 61400-3 (2009) and GL Offshore guideline (2012) are two commonly adopted guidelines for certification of offshore wind turbines worldwide. Comparison of load calculation during normal and idling situations between these two guidelines is performed in this paper. The NREL 5 MW wind turbine with monopile support structure is selected as the reference wind turbine system. Study of the impact on the loading conditions is conducted in this paper. Design load case (DLC) 1, 6, and 7 are considered in this work and the focus is on the Class I system with different turbulence characteristics (category A, B, and C). Both of extreme and fatigue loads are derived at critical components such as blade, shaft, tower, and foundation. The major impact is investigated and identified in this paper.
