THE DISTRIBUTION OF LOCAL ICE PRESSURE ACTING ON OFFSHORE STRUCTURE

Abstract

The distribution of local ice pressure acting on offshore structure in ice-infested sea area is investigated through data obtained by the plane pressure panel sensor in in-situ ice/structure indentation test using sea ice. The local ice pressure is characterized into two types depending on indentation velocity (V) divided by ice thickness (h). This is why ice failure pattern depends on (V/h). In the paper, an approximation curve of the ice pressure distribution is proposed as a multiple of uni-axial compressive strength of sea ice.
