The hydrodynamic pressures due to random waves around a pipeline near a rigid bed of slope 1:10 have been measured. The tests were performed for pipelines normal and parallel to the wave direction. These tests were carried out for three gap ratios of the pipeline from the sloping bed. The pressures were resolved in the horizontal and vertical directions and integrated for the force time history in the respective directions. The effects of relative clearance of pipe from the bed and wave steepness on the probability distribution of the forces on the pipeline are reported. The average statistical force ratios as a function of scattering parameter and the variation of the force coefficients as a function of Keulegan–Carpenter number are also presented. The details of the model setup, experimental procedure, analysis of results and discussion are reported in this paper. [ABSTRACT FROM AUTHOR]
