AbstractThe effect of lateral ice pressure on the level ice resistance of a 1/30 scale model of an OBO is examined experimentally. The model was equipped with an instrumented side panel. The apparatus for producing lateral pressure is described, as well as the model tests themselves. Ice pressure were recorded using extensimeters mounted in the ice. The results indicate that the compressive pre-stress in the ice had little or no effect on the breaking resistance. However, as the model moved well into the pressurized region ice was forced against the hull and very high lateral loads were generated giving rise to frictional resistance. The test results indicate that bow reamers may be beneficial when operating in pressurized conditions.
