Fixed Bottom Tripod Type Offshore Wind Turbines under Extreme and Operating Conditions

摘要

The focus of this article is a complete analysis of a fixed bottomoffshore wind turbine tripod type for both operating and extremeconditions. Time histories of the rotor load and the resulting forces atvarious levels of the structure are presented. The percentages of therotor load contribution to the stresses of the structure componentsduring power production are investigated and shown. The percentagesof the structure components’ stress for Operating conditions incomparison with these for Extreme conditions reveal the regions wherethe loadings of the power production state dominate and, thus,determine the design.
