Paper Title: Experimental Fatigue Analysis of an Offshore Wind Power Generation Facility

Abstract of the paper

This is a great possibility to introduce wind power generation to offshore. Because, the offshore wind velocity it stronger than onshore wind velocity. And, there is little issue of acoustic noise and so on. It is generally recognized that the cost of wind power generation in offshore is more expensive than onshore. We believe that the wind power generation offshore has many advantages and we should have to develop it. This paper reports on a case study of fatigue analysis based on observed oceanographic data. The hypothetical wind power generation facility prepared for the analysis consists of the tower which has a 2400kW generator, and mono-pile foundation constructed on the bottom of the sea at a depth of 10m outside a breakwater. Fatigue analysis was executed by the zero-upcrossing method and rain-flow method. It was concluded that the fatigue life of an offshore wind power generation facility can be analyzed by those methods, and it was proved that a facility with a mono-pile foundation has an adequate fatigue life even when it cannot be repaired based on an inspection prescribed by DNV.
