A set of routines that calculate time-domain loads induced by surface ice on offshore substructures, for use with wind turbine aeroelastic simulation codes, including FAST.

The U.S. Department of Energy (DOE) awarded the University of Michigan a project to create a model for interaction of bottom-fixed offshore wind turbines with surface ice for use with common simulation tools. The IceDyn module, which conforms to the standards of the FAST Modularization Framework, was created from this project.

The IceDyn module includes 6 ice mechanics models that incorporate ice floe forcing, deformation and failure and structure geometry. The six models are: quasi-static ice loading on vertical structure, dynamic ice loading on vertical structure, random ice loading on vertical structure, non-simultaneous ice loading on vertical structure, ice loading on sloping structure and large ice floe impact.
