Incorporation of Multi-Member Substructure Capabilities in FAST for Analysis of Offshore Wind Turbines

H Song, A Robertson, J Jonkman, D Sewell – Offshore Technology Conference, May 2012

This paper addresses the methods used for incorporating the hydrostatic and hydrodynamic loading on multimember structures in the (Fatigue, Aerodynamics, Structures, and Turbulence (FAST) code through its hydronamic loading module, HydroDyn. Modeling of the hydrodynamic loads was accomplished through the incorporation of Morison and buoyancy loads on the support structures. Issues addressed include how to model loads at the joints of intersecting members and on tapered and tilted members of the support structure
