Abstract
The objective of the paper is to provide an assessment of the air bubbler system in terms of ship performance in various ice conditions. In order to measure the ship performance with/without the air bubbler system, various sensors were installed on the CCGS Henry Larsen to measure performance information including thrust/torque/RPM from both shafts along with ship speed, heading and location. The National Research Council of Canada (NRC) and C-CORE also installed a Situational Awareness (SA) sensor package. From this ice trial, the air bubbler system demonstrated performance benefits in confined brash ice, snow covered pack ice, and the tightly packed shear zone. The detailed data analysis and results are provided and the recommendations are discussed.
