A Direct Time Domain Simulation of Floating Structures With Mooring Lines

A direct time domain method is established for analyzing the interactions between the floating structures and mooring lines. The motions of floating structures are solved by a Rankine Panel method in time domain, while the static restoring force characteristics of the mooring system is taken into account. As numerical examples, the motions of two SPARs are solved by this direct time domain method. The numerical results of present method are analyzed and compared with model test results.
