Abstract Third harmonic loads on a vertical cylinder in irregular or regular longcrested waves in deep water are analyzed. Characteristic wave lengths are large relative to the cross-dimensions of the cylinder. Characteristic wave amplitudes are of the same order as the cylinder cross-dimensions. The method is a generalization of the FNV method (Faltinsen, Newman and Vinje [1]) for a circular cross- section. Integral theorems and auxiliary potentials are used to simplify the force expressions. Details are shown for Lewis form sections. Completely analytical expressions are derived for elliptical cross-sections. It is demonstrated that the third harmonic loads are sensitive to the cross-sectional form.
