Catenary system

A Catenary System includes all catenary mooring lines connected to one body. A catenary mooring system is built from several components:

Each mooring line must be uniquely specified by a Catenary Line. Typical line data are fairlead coordinates, line direction, pre-tension and winch run length.
Each line must refer to a line characteristics specified by a Line Type.
The line characteristics (force-displacement relationship) may be given directly, or by the data needed by SIMO to calculate it.
Such data may typically be segment properties (weight, stiffness, drag coefficients), vertical position of the anchor and bottom slope.
Several lines within one catenary system may refer to the same line characteristics.

If the line characteristics are to be calculated by SIMO (Segmented Line Types), the user may include buoys in the intersection between line segments.
The buoys may have depth dependent buoyancy, and are specified by the Buoy Type component.
Several Segmented Line Types may refer to the same buoy data.

A catenary system can be converted to a RIFLEX Slender system by right-clicking the Catenary System folder in the navigator and choose Convert to new RIFLEX task. See here for details.
