THE DESIGN OF POLAR ICEBREAKERS

A systematic procedure for the design of polar icebreakers is given. To start the procedure and insure rational selection of ship size, powering and other features, a detailed list of owner requirements is necessary. Development of such requirements through the use of operations research methods is briefly discussed. The design procedure generally follows the traditional ship design spiral, but is modified where necessary for the design of icebreakers. Only those aspects of the design spiral peculiar to icebreakers are discussed in this paper. These include development of the hull form, calculation of icebreaking resistance, selection of the propulsion system, determination of hull scantlings, and investigation of beached stability. Wherever possible, analytical methods are presented. To accelerate the convergence of the design procedure and to assist the owner in matching his requirements to the resources he is prepared to expend, use of a computerized approximation of the design procedure is recommended. Some results concerning least-cost icebreaker proportions and the effects of key owner requirements on size, power and cost, obtained from one computerized version of the procedure, are included. Sufficient information for developing a similar approximation of the procedure is presented throughout the paper.
