THE BRITTLE STRENGTH OF STRUCTURES IN ICE SHIPS

Hull structures in ice ships are constantly exposed to low temperatures, which reach -50 deg C on some Arctic routes. The objective formulation of steel cold resistance is therefore important in guarding against brittle failure and ensuring operational reliability. Several special studies performed to clarify these requirements, and the results, are briefly presented. It is concluded that current structures have such large margins of resistance to brittle failure that consideration should be given to lowering the requirements concerning steel in cooled structures.
