When calculating the effects of dynamic or time varying ice loads applied to an offshore structure such as a bottom founded gravity base structure (GBS), it is of prime interest to know what percentage of the ice load applied at the waterline is transmitted to the foundation. The inertia and damping of the GBS will result in attenuation of the applied load and only some fraction of it may “reach” the foundation. This paper addresses this issue in a preliminary manner using stiffness and mass parameters appropriate for the Molikpaq as it was installed at Amauligak in 1986.
