MODELLING ASPECTS OF WAVE KINEMATICS IN OFFSHORE STRUCTURES DYNAMICS

Magnitude and phase related issues of modelling of ocean wave kinematics are addressed. Causal and non-causal filters are examined. It is shown that if for a particular ocean engineering problem only the magnitude representation of wave spectra spatial relation is critical, analog filters can be quite useful models in conjunction with the technique of statistical linearization, for calculating dynamic analyses. This is illustrated by considering the dynamic response of a simple model of a guyed tower.
