Abstract: Ice model tests have been performed on a newly designed ice protection structure, termed the Shoulder Ice Barrier (SIB), in the large ice tank of the Hamburg Ship Model Basin (HSVA). The model tests in ice were part of the SIB concept verification study. This paper analysis the rubble build-up on the SIB under the influence of various observed ice failure modes. Special attention is attributed towards investigating distinct phases of rubble build-up and their accompanying ice forces to the SIB. In the mode where the ice sheet fails on mobile rubble situated upstream, the observed ice forces are typically high of short duration. An attempt of relating ice breaking frequency to the periodical ice failure is herein presented.
