COMMENTS ON SECOND-ORDER WAVE EFFECTS ON LARGE-DIAMETER VERTICAL CYLINDER

In a recent paper, Raman et al (RJV) presented a second-order solution for the wave interaction with a large-diameter, bottom-mounted, surface-piercing, fixed vertical cylinder. Earlier, Chakrabarti obtained an approximate solution for the vertical cylinder due to Stokes's fifth-order wave. Later, Yamaguchi and Tsuchiya (YT) proposed a second-order solution in a closed form for the wave interaction problem with the vertical cylinder which was examined by Chakrabarti. All these solutions are different due to the assumptions regarding the frequency of the scattered wave and the kinematic free-surface boundary condition. RJV claim that their solution is superior to the earlier solutions because, according to them, it satisfies the nonlinear free-surface boundary conditions completely. The purpose of this note is to show that the RJV solution is not necessarily any better because it does not satisfy the kinematic boundary condition similar to the other solutions. It will also examine the three nonlinear techniques, the approximations involved in the respective derivations, and the results, in particular, of the two proposed second-order solutions.
