Similar to the Flexible Riser format, the mass per unit length is a user input in the Mooring Line format. The mass per unit length is a measure of the inertia of the structure with respect to translation.
Similarly, the polar inertia is a measure of the inertia of the structure with respect to torsional rotations about the cross section axis. In practice however, the influence of polar inertia on the solution in very many cases is small, and so for convenience, a nominal value of 1.0 is assumed for the Mooring Line format. The dimensions of p are [Mass][Length]. In the SI system of units, p is typically in kg.m. In Imperial units, p is typically in slugs.ft.
