Abstract:Based on the multiple-cylinder diffraction solution, systematic calculations are made about multidirectional random wave loads on cylinders. The time series of multidirectional wave loads can be calculated. The effect of wave directionality on the wave run-up and wave loading on large-scale cylinders is investigated. For multidirectional random waves, as the wave directional spreading parameter s becomes small, the wave run-up on most of points around cylinders would be larger. This means that the wave run-up on multidirectional wave condition is larger than it for unidirectional wave. The effect of wave directionality on the transverse force is more obvious than on the normal force. The transverse force on the front cylinder is not always larger than that on the back cylinder, especially, for smaller s. As a consequence of the results, the engineering project design based on unidirectional waves cannot always give a conservative estimate.
