On the wind and current forces acting on a very large floating structure

This paper deals with the estimation method of wind force and current force acting on a very large floating structure. In this paper, as a very large floating structure, we consider a matlike very large platform which will be used as a floating airport, In order to estimate the fluid drag coefficient for such a huge structure, wind tunnel and towing tank model experiments were conducted paying special attention to the frictional drag coefficient. This paper shows the methods and results of these model experiments and discusses the application methods for wind and current forces on a full-scale structure.
