Estimation of the fluid force on a body in free surface oscillatory flow has become more important and indispensable nowadays since offshore structures have been or will be built: in Japan, for example, the Kansai International Airport and Chubu New International Airport (tentative name) are to be constructed in the near future. Offshore structures are classified as either large bodies on small bodies. Several states of the arts have been reported, but no papers have concentrated upon conditions for applying the Morison equation to small structures. We thus clarify the physical significance of the Morison equation, which has not been studied in detail so far, describe hydraulic characteristics and errors of a drag coefficient and an inertial coefficient of a cylinder and furthermore mention pipelines which have recently drawn attention. In this paper we will review earlier studies and give some practical ideas for further researches.
