This paper discusses the experimental determination of hydrodynamic coefficients of Morison equation for slender circular columns oscillating under sinusoidal wave action. Two types of columns are considered for study. Column-1 is a rigid circular column, hinged at the sea bed and the response oscillation is in the form of angular displacement. Column-2 is a flexible circular column, fixed at sea bed and the response oscillation is in the form of structural deflection. The columns are oscillated by sinusoidal waves in a two-dimensional wave tank and the responses are recorded. The hydrodynamic coefficients associated with the wave force equation are determined and are plotted against Keulegan-Carpenter number. The results are compared with the values given by other researchers and show a fairly good agreement.
