Abstract :
The effect of wave groups and an associated forced second-order wave system on a fixed offshore structure is examined analytically. Based on the modified Morison´s equation approach, the dynamic response of a single degree of freedom, fixed offshore structure is investigated using a primary wave system with and without the second-order wave system. By comparing the results, it is found that the second-order wave system can significantly affect structural response. This is particularly true of structures in shallow water.
