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. Catsim supports surface and
submerged buoys, clumped weights and individually specifiable
anchor depths, but not sloping bottom conditions. Output capabilities
include both individual line characteristics and net restoring
forces and moments associated with rotational offsets about any
oblique axis or translational offsets in any direction. Automatic
evaluation of the force-moment equilibrium configuration associated
with user-specified external forces and moments acting in conjunction
with hydrostatic and mooring forces and moments is a built-in
option.
