FREQUENCY CONTENT SELECTION FOR DYNAMIC ANALYSIS OF MARINE SYSTEMS

A recommended discretization of a wave spectrum for numerical analysis of the structural response of compliant marine systems is presented. Error estimates for the variance of structural response are presented as a function of system damping and spacing of frequencies in the discrete wave spectrum. Application of the recommended frequency spacing to calculation of the tendon tension response of a tension leg platform, with particular attention to resonant pitch response, is presented. The applicability of the recommended discretization to time domain simulation is discussed and recommended frequency spacings and simulation lengths are presented.
