Very frequently the length of ambient waves λ is large compared to the dimension of floating bodies. For example the length of a wave with period T = 10 s is λ ≃ T 2 + T 2 2 ≃ 150 m. The beam of a ship with length L = 100 m can be 20 m as is the case for the diameter of the leg of an offshore platform.
