Abstract

Morison et al. proposed a formula to estimate the wave forces generated from unidirectional regular waves in assumption that the presence of the slender body as an object did not affect to the characteristic of the wave field. It assumes that the force derived from this effect is composed of inertia forces and drag forces added together. These components require the knowledge of an inertia coefficient and a drag coefficient which are determined experimentally. Practically, uni-directional or the long-crested waves are commonly used in the design of offshore structures for estimation of wave forces exerted to the structure. Instead of regular waves, shortcrested waves are much better model to represent the waves generated by wind in oceans and short-crested waves have many different properties compared to longcrested plane waves. Hydrodynamic force coefficients on rigid vertical cylinder was investigated on an experiment of hydrodynamic coefficient induced by long crested wave. However, to the author’s knowledge, no-one seems to have discussed the experimental investigation of hydrodynamic coefficients on rigid vertical cylinder in short-crested waves
