WORK PACKAGE 3 (WP3)
The work on fixed structures is sub-divided into Ice-induced vibrations and Ice ridge
action.
SAMCoT WP3 researchers study how the structural vibrations of a structure affect the
ice pressures. Furthermore, the Numerical modelling of Ice Induced Vibrations (IIV)
considering the contact between ice and structure was applied for a detailed analysis of
the forced vibration experiments from the autumn of 2011, where WP3 researchers were
involved and developed novel scaling and dimensionless parameters for ice-induced
vibrations. WP3 has also conducted full-scale field work to examine in-situ ice ridge
properties and the development of a numerical model for ice ridge action on structures
based on WP2 is well under way.
In 2015 WP3 researchers have started the modelling on ice load estimation through
combined finite-discrete element simulations trying to achieve a better understanding of
the nature of variability in ice loads.
