Elastic Characteristics of TLP Type Offshore Wind Turbine
In this paper, we will discuss about structural problems affecting TLP type offshore wind turbines under wind and wave conditions. For TLP type offshore windturbines, structural problems haven’t been found yet, however when talking about the use of wind turbines on a TLP structure we come to realize certain problems. For example the bending vibration of the tower and the blades, the bending moments and inertia of the upper structure under heavy sea conditions that might affect the mooring lines. Those are pressing issues and it is therefore important to take them into consideration. So, in this study, we will perform some experiments using appropriate “elastic model” of TLP type offshore wind turbines to observe those effects. We have not only measured the loads on tension legs in waves and wind but also the bending stresses acting on the tower and blades. We observed some phenomenon that will be reported later on, in this study.
