Mean Wave Drift Force

 

The current speed is 0.9 m = 1.75 Knot

(the figure 1 can be used with the drift motion for speed 0 to 2 Knots, and Hs = 12.8 m ~ 13 m)

 

We get from figure 2:

 

Fmdx = 62.92 kips = 137.8 kN

 

The current speed is 0.9 m = 1.75 Knot

(the figure 3 can be used with the drift motion for speed 0 to 2)

 

Fmdy = 231 Kips = 1027 kN

 

 

Fmdz = 1036 kN
