Outline of Research at the Start |
海上輸送は現代社会にて物流の大動脈であり、天然資源が豊富な南半球と人口集中する北 半球の輸送拡大が予測される。しかし南半球は観測点が疎らであり、気象機関が公表するデータ内容にばらつき(気象の不確実さ)が見られ、船舶へ強く影響する南極からのうねりや大陸沿いに卓越する海流の推定精度はほぼ未検証である。 本研究は、実船データをもとに現地調査および数値計算にて気象の不確実さを低減する斬新な方法論を構築し、運航変化の高精度な推定を実現することにより、輸送需要が今後増加する南北間の海上輸送の高度化に大きく貢献する。

Outline of Annual Research Achievements |
Research Achievements have been achieved in the year of 2022 including several journal-published papers such as "Comparative study of realistic ship motion simulation for optimal ship routing of a bulk carrier in rough seas"、"Novel safety evaluation technique for ships in offshore anchorage under rough seas conditions for optimal ship routing" as well as "Uncertainty Analysis of Weather Simulation Modeling during Navigation". These above-mentioned papers have focused on the key issues such as the uncertainties of weather forecast、the best method to make a realistic ship motion simulation, and the safety evaluation technique of offshore ship anchorage under rough seas conditions occurred in the North-South route, for which the attention and efforts have been made to construct the optimal ship routing system for the North-South route in the next step.

Current Status of Research Progress |
Current Status of Research Progress
2: Research has progressed on the whole more than it was originally planned.
Reason
As a visiting associate professor in the Kobe University, most of the research achievements have been done with the tight cooperation with professor and researchers in Kobe University, considering the effects of the Covid-19 in the past time.
|
Strategy for Future Research Activity |
As the effects of the Covid-19 have gone away, the future research is supposed to be done with much more communication with researchers including Prof.Sasa in Kobe University. Short period visit to ship getting the on-board observation data as well as the face-to-face discussion of the next-step study with Prof.Sasa in Kobe University will become possible and anticipated.
