POLAR CLASS ICEBREAKERS--CONTRIBUTION TO TECHNOLOGY

The purpose of this paper is to present the status and results of various tests, experiments, and design modifications for the U.S. Coast Guard Icebreakers, Polar Star and Polar Sea. Areas discussed include: controllable pitch propeller design, performance, ice test results, and modifications; vessel vibration problems, vibration test program and proposed modifications; status of technology advancement studies related to current test programs and operational experience (hull appendages, bottom coatings, and propeller loading analysis).
