according to the diffraction approach, related to the Morison formula
wavelengths. The lack of the drag force in the diffraction approach is negligible when
compared with the resulting total force.
The differences between the results of the two methods of calculation will be illustrated
below with the help of a more realistic example [32]. To do this we will investigate a
large-volume reinforced concrete offshore foundation structure for a wind turbine with
a design typical for the North Sea. Figure 2.48a shows the geometry of the structure
(see also Section 5.4.2).
