WebOct 12, 1999 · This paper is concerned with the mooring line damping induced by the low-frequency, quasi-static, horizontal motion of the mooring line fairlead. The main advantage of the quasi-static approach is that it is much faster than the more accurate finite element methods, and, secondly, that it does not require any finite element modeling skills. WebFEAMooring is a finite-element-based mooring-dynamics module. A Texas A&M University-led team, in partnership with NREL, was selected for funding to develop an open-source mooring-dynamics module for the analysis of floating offshore wind turbines. FEAMooring calculates the mooring-line reaction forces at the fairlead positions of the …
