THE INFLUENCE OF SLOWLY VARYING WAVE FORCES ON MOORING SYSTEMS

Various excitation sources that have to be considered in design of mooring systems for structures subjected to wind, wave and current loading are reveiwed. Furthermore, a state of the art review of mooring system design methods are presented. Wave drift forces and slowly varying wave forces are important excitation sources and are given special attention. A better understanding of the effect of slowly varying forces in design of mooring systems is of great importance for a safe design. A numerical model for non-linear dynamic time domain analysis of mooring systems capable of handling the real time varying nature of such forces has been developed. This model is used in sample calculations and compared with quasi-static calculations in order to study the effect of slowly varying wave forces in particular. Recommendations on the applicability of the different methods are given.
