STRUCTURAL CONSIDERATIONS IN THE DESIGN OF THE 'POLAR' CLASS OF COAST GUARD ICEBREAKERS

The design of the Coast Guard's POLAR Class icebreakers incorporated the results of four years of research, analysis and testing aimed at optimizing the structural design. Operation and load data were gathered by instrumenting existing icebreakers. Extensive tests and studies of available steels as well as a methodical analysis of reported structural failures were undertaken to assist in the selection of hull materials. Various finite element analyses were conducted for portions of existing and proposed structural arrangements with special emphasis on the forward structure. With the cooperation of other agencies, studies of the strength of sea ice led to updated concepts of loading that resulted in significant changes in design philosophy and refinements over previous icebreaker designs.
