Owing to the great increase in the exploration and exploitation of offshore oil and mineral reserves, a variety of structures are being built in the marine environment, most of which are supported on piles. Cylindrical tubular members frequently form an integral component of offshore structures such as bridges, wharves, piers, drilling and production platforms, floating breakwaters, articulated mooring towers, etc. The variation of the dynamic pressures around a circular cylinder due to regular waves is studied in a wave basin of constant water depth of 3m. The measuring segment consisted of 12 pressure transducers placed at an elevation of 0,8m below the still water level. The tests were conducted with the cylinder axis inclined with respect to the vertical plane along and against wave direction. The results on the variation of dimensionless pressures with the non-dimensional input wave parameters are reported for different angles of orientation of the cylinder. The sectional normal force obtained by integrating the pressures is also presented as a function of wave steepness and the effect of angle of orientation of the cylinder is also reported.
