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