    Abstract

    This paper studies the behaviour of a mooring system, in water depths from 300 m to 3000 m, using an indirect time-domain method. The boundary element method and lumped mass method are used to investigate the floating body hydrodynamics and mooring line characteristics, respectively. Results from coupled analysis are compared with experimental data in intermediate water depth. The results from coupled low frequency (LF) and fully coupled analysis are compared and discussed. Results from parametric studies are compared to offer guidance to mooring system designers on the suitability of particular approaches.
