THE STRENGTHENING OF SHIPS WITH ICE

In the interest of pollution prevention, it is proposed that ships may be reinforced against external sea ice damage using a double hull filled with ice. The background on the use of ice as a structural medium is discussed and the pertinent mechanical properties of ice (elasticity, creep, ultimate strength, expansion, regelation, grain size and composite reinforcement) are reviewed. A brief theoretical analysis of the steel-ice-steel sandwich is presented and its theoretical effectiveness is discussed. The author describes the equipment used in conducting experiments on ice filled double shell specimens and explains the procedures followed in determining the load-deflection characteristics of the models in response to static concentrated and distributed loads and dynamic concentrated loads.
