... such as current and wind. The forces acting on the floating structure consist of hull forces , wind forces and tension forces due to mooring lines. Current forces are included in the hull forces. The equations of motion of the floating structure are expressed as follows, (1) where, : mass, : added mass components...

... of wind turbine, the wind force, and the ocean wave force. In the analyses, we especially focused on the connection between the tower and the supporting structures, because wind force and ocean wave force may cause the damage to occur at the connections. In the model of the monopile structure, the grout...

... Abstract When FPSO is operating in a given oilfield, the environment load including wind, wave and current force will act on it. The wind force is a constant force which will drag the hull away from the original position. It is very important to calculate the wind force correctly in FPSO...
