Abstract

The development of floating wind farms that are far from the mainland is currently of great interest all over the world in order to reduce impacts on the coastal landscape and to increase the electricity producing factor, etc. In fact, several studies have shown that the application of floating structures to support the wind turbines seems to be a feasible solution except for some technical issues such as how to reduce the floating structure motions and to choose appropriate materials for mooring line components, etc. This study focuses two on semi-taut mooring systems (i.e. with the application of conventional chain plus synthetic ropes such as polyester and nylon) for a semi-submersible type floating wind turbine. Time domain analyses are performed in Ultimate Limit State (ULS) and Fatigue Limit State (FLS) in order to study the dynamic responses of mooring lines and the floating structure motions. The outcomes of this study can be used as a basis for selecting synthetic mooring components and also for highlighting some current modeling approaches and technical criteria for such mooring systems.

Keywords:
