This study was performed to determine the requirements for United States Coast Guard icebreakers in polar regions for the time period 1973-2000. Of the organizations queried that were associated with economic resources and planning, none could provide any projection on rates of growth and development in the polar regions. As a consequence, there is no basis for predicting the number of icebreakers required to support this anticipated development. The ships' operating and power profiles were developed, and the icebreaking requirements (power plant shaft horsepower) were determined for the geographic areas of operation. Icebreaker displacement was estimated by determining tonnage equivalents for operating spaces and personnel habitability spaces, and calculating power plant fuel consumptions (tons). An analysis was performed to determine the effects of constraints imposed by crewing limitations, overhaul scheduling, and power plant icebreaking ability. The results were then applied to a cost analysis to determine the relative cost and effectiveness for alternative combinations of ships and constraints. (Author)
