FEAMooring

FEAMooring 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 floating platform considering the mooring dynamics, including inertia and drag forces at each line element. It has been coupled into the FAST wind turbine engineering tool, although FEAMooring can also be driven as a standalone code to compute mooring dynamics uncoupled from FAST.

The module can analyze several kinds of mooring systems, including catenary mooring, taut mooring, vertical tendons, etc. provided that the proper line geometry and properties are specified. While powerful, FEAMooring has the following limitations:

  • Only single uniform mooring lines between the fairlead and anchor are considered; it is not possible to model multi-segmented lines, line interconnections, or weights/tanks.
  • Mooring-line bending stiffness is not considered.
  • Seabed friction is not considered.
  • Interface does not support coupling to HydroDyn; the added mass, drag, and buoyancy calculations assume still water.

This software was developed by Yoon Hyeok Bae of Texas A&M University.

The archives below are for FEAMooring v1.02 used in FAST v8. Newer versions and ongoing development now take place in GitHub in the OpenFAST repository.
