Abstract: Ice force acting on an offshore structure designed for use in ice-infested seas has been evaluated assuming a perfect (idealized) contact between leading edge of ice sheet and offshore structure. However, in the actual sea, the leading edge of an ice sheet is highly irregular. Small-scale indentation tests were conducted in the field to examine the effects of irregular contact conditions between ice sheets and rectangular pile indentors on ice force using freshwater lake ice in Hokkaido. On the basis of test results in this study, ice force in an idealized contact condition is approximately 1.25 times as large as that in an irregular contact condition.
