Abstract: While there are diverging results, both empirical and theoretical, on the effect of penetration rate on load when an ice field hits a pile, there is unanimous agreement that the maximum force occurs if the pile is allowed to freeze into the ice and the ice subsequently begins to move. In Arctic waters with weak tides, there is a good chance that adfreezing of ice to a structure occurs. Whether the ice field is intact or consists of broken ice, the regular forces caused by a slow drift will then govern the design of the structure. This design strategy presumes that the arrival of icebergs, ice islands or certain pressure ridges is an unlikely event. If attacks by such ice forms that will undoubtedly cause destructive forces are imminent, the endangered platform must be removed, Or perhaps allowed to drift.
