| Outline of Final Research Achievements |
The aim of this study develops the ice management supporting system for the safe and efficient ship and offshore structure drilling in an ice sea field. Ice management simulator was developed to estimate strategy of icebreakers deploy for ice management. Principal investigator attended the filed measurement of sea ice strength and sea ice trial for investigation of the ship maneuver in real ice sea, which were conducted in Van Mijen Fjord, Svalbard and North-West Barents Sea. The numerical model can obtain the ice force and the ice floes distribution in the quasi- sea ice conditions. Those data can be used to decide the safe and efficient operation in ship drilling. The measurement of the real sea ice data significantly depended on the sea ice conditions and ship ice performance. The data obtained in those measurement cannot be used in the numrical model direcly. Principal investigator, however, acquired the skills to conduct the real sea measurements.
