Model tests on the Shoulder Ice Barrier (SIB) were performed in the large ice tank of the Hamburg Ship Model Basin (HSVA) during July 2007. The concept of the SIB has previously been presented in a companion paper under the same title at the OMAE 2006 (Gu¨rtner et al., 2006). Model tests were performed to investigate the conceptual design and force conditions under ice impact. Design conditions for the Northern Caspian Sea were assumed for the model tests. The characteristic shoulder sections’ inclination has been varied to investigate their contribution towards stabilizing broken ice and to prevent ice from over-riding. Ice up-riding onto the barrier contributes towards increased vertical forces. The global vertical forces showed to be higher than the global horizontal forces, and in particular when ice grounding was observed. Even under extreme rubble heights of up to 9.4 m (full scale), ice overtopping the structure was effectively prevented. The SIB showed the potential to be utilized as ice protection structure for future shallow water developments.
