The report describes the development and design of icebreakers, discusses methods of calculating their ice performance, design and arrangement features and points out paths toward further improvement. All present Soviet and foreign icebreakers are described, their operating conditions are analyzed, the basic ice performance characteristic of an icebreaker are examined (ice speed to power ratio, ice strength, maneuverability, jamming conditions), and methods of evaluating these qualities, developed by Soviet specialists, are set forth; the design features of the basic machinery and systems of icebreakers are noted; recommendations on their design are presented. A considerable part of the book is devoted to features of the choice of hull shape, main dimensions and power plant. Data on icebreakers hull design and relations for determining the strength dimensions of the framing and plating are presented. (Modified author abstract)
