FIELD STUDY CONCERNING INFLUENCE OF WAVE CHARACTERISTICS FOR SUPPORT STRUCTURES OF OFFSHORE WIND TURBINE

Abstract

 This paper introduces results of field study using the offshore observation tower system constructed off the Kita-Kyusyu city, aiming to clear-up the influence of wave characteristics for the rational design of offshore wind turbine support structures. It was shown that fluctuations of normal offshore winds were affected by waves and thermal conductions from sea surface. The idea of rational combination of abnormal wind and wave actions was shown by Inverse First-order Reliability Method (IFORM).
