Wave Forces on Inclined Circular Cylinder

Abstract

The integral equation method is utilized to calculate the wave‐induced loading on a surface‐piercing cylinder of circular cross‐section inclined at an arbitrary angle to the sea bed. Numerical values of the various force and moment components are presented for a range of wave and cylinder parameters. The computed estimates of the force coefficients show good agreement in the inertial limit with published experimental results. In addition, the estimates confirm that the inertia force on an inclined cylinder may be severely underestimated by using the vectorial form of the Morison equation with a mass coefficient appropriate to the corresponding vertical cylinder case.
