CATSIM

Catsim is a second-generation comprehensive static mooring analysis program for multileg catenary mooring systems. Catsim's strengths include the ability to accommodate the latest generation of complex deepwater mooring systems and the ability to compute line tension variations for arbitrary quasi-static motions, including rotational offsets about any oblique axis and translational offsets in any direction. These capabilities are used, in particular, for ruptured-hull damage analysis of moored vessels and for a new class of multileg mooring buoys with variable vertical positioning capabilities. Catsim shares with Statmoor the exact solution to the elasto-gravitational static response of mooring line elements, permitting analysis of strongly nonlinear materials such as nylon and polypropylene. Extensive on-line default values for weight, strength and elastic properties of steel and synthetic mooring materials are provided to enhance efficiency in preliminary parametric design studies...
