The impact of a large ice floe with the Molikpaq on May 12, 1986 resulted in some of the highest measured loads on this offshore structure. Video data from the event have been studied to produce refined estimates of ice thickness, rubble height and rubble extent. Ice load estimates are made based upon instrumentation as well as an analysis of the floe deceleration. Individual aspects of the event, such as the possibility of grounded rubble, a fracture in the floe and the apparent overloading of one pressure panel, are also studied with relation to the effect on global load.
