Description

Length:

The length of the mooring line.

Min Mesh Density:

The minimum element length to be used in creating the finite element model of the mooring line.

Max Mesh Density:

The maximum element length to be used in creating the finite element model of the mooring line.

Diameter:

The diameter of the mooring line.

Hydrodynamic Properties

Input:

Description

Normal Drag Coefficient:

The drag coefficient for the direction normal to the mooring line.

Tangential Drag Coefficient:

The drag coefficient for the direction tangential to the mooring line.

Normal Added Mass Coefficient:

The added mass coefficient for the direction normal to the mooring line.

Tangential Added Mass Coefficient:

The added mass coefficient for the direction tangential to the mooring line.

Structural Properties

Input:

Description

Axial Stiffness:

The axial stiffness for the mooring line.

Mass per Unit Length:

The mass per unit length of the mooring line.

Stiffness Damping Coefficient:

The stiffness proportional damping coefficient for the mooring line material. Refer to Damping Coefficients for further details.
