The objective of the project was the quantitative evaluation of the cost and effectiveness of air cushion configurations in icebreaking applications with displacement ships in level ice fields. Simple theoretical methods were developed for the prediction of the air cushion icebreaking capability in the low speed and high speed icebreaking modes. Conceptual designs for air cushion icebows and air cushion icebreakers were prepared and the economic analysis of their use with the displacement ships is reported. The self propelled air cushion icebreaker was determined to provide more flexible operational capability and was more cost effective for the cases examined.
