A finite-element-based mooring dynamics module for FAST v8

A TAMU-led team, in partnership with ABS and NREL, was selected for funding under topic area 1.3 of DE-FOA-0000415 to develop an open-source mooring-dynamics module for the analysis of floating offshore wind turbines. This project led to the development of FEAMooring (or FEAM), a finite-element-based mooring-dynamics module that has been coupled into FAST v8. FEAMooring can also be driven as a standalone code to compute mooring dynamics uncoupled from FAST.
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. 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:
The final report on this FOA 415 project.
The FEAMooring archives contain documentation, sample input files (including input files for all the 5MW-turbine configurations included in the FAST archive), and all the source code necessary to compile the driver project. You may choose from two different formats:
This is a self-extracting archive of FEAMooring for Windows. It also contains the Windows® executable of the FEAM driver.
This is a compressed archive of FEAMooring for non-Windows® users.
