Abstract
The Gulf of Bothnia has the potential for large capacity
wind farms because of the relatively high and constant
wind velocities. The mostly shallow coastal areas enable
cost-efficient foundation and grid connection. However,
the sea freezes annually introducing the most significant
uncertainties in the support structure design for
offshore wind turbines. The magnitude and time variation
of sea ice load depends on various factors, like the
thickness and velocity of the ice as well as the size and
shape of the structure. A feasibility study of the FAST
(fatigue, aerodynamics, structures and turbulence)
simulation software was carried out investigating the
structural performance of offshore wind turbines. Various
load combinations and operation modes were studied by
taking into account coupling between the ice, wind and
structural response. Coupled modelling of ice-structure
interaction is a necessary step in terms of
cost-efficient structural design.
