Abstract

Abstract—The predominant aspect of interest, presented in this study is the influence of wave heights and cylinder diameters on the wave forces acting on cylindrical members. The effects on the wave forces due to the interactions between the adjacent cylindrical members are also presented. Model tests were conducted in the wave tank, on cylinders of four different diameters with wave characteristics pertaining to three major offshore sites of Malaysia. This particular paper, however, is limited to a discussion on rigid, vertical cylinders in regular waves. In the studied cases of wave heights and cylinder diameters, it was observed that the variation of cylinder diameters is having a prominent effect on the wave forces rather than the variation in wave height. The results also depict that the proximity of other members significantly affect the wave forces on the considered member. The primary area of application is intended to be the design of jacket type platforms, risers and conductors. Keywords — wave forces; wave height; cylinder diameter; regular waves; proximity
