A Research and Development on the Navigation Support Station of Weather Routing to Reduce Fuel Consumption

为选择最佳航线以降低燃油消耗，我们研究并开发了具有（1）气象数据管理功能、（2）船舶性能评估功能和（3）最佳航线选择功能的导航支持站。在（1）中，利用集群计算系统进行了风浪预报，验证了预报的有效性和实用性。并建立了气象数据管理系统。在（2）中，通过抽象的航海日志分析和性能模型，开发了各船的性能估计算法，并证实了实用性。（3）实现了全球范围内的最优航路计算，并对计算结果进行了验证，展示了某海域最优航路的特点。

A Research and Development on the Navigation Support Station of Weather Routing to Reduce Fuel ConsumptionTo select the optimum route to reduce fuel consumption, we research and develop of the navigation support station having the function of(1) weather data management function,(2) estimation ship performance function and(3) selecting optimum route function. On(1), using a cluster computing system, the wind and wave forecast were made and the validity and practicality of the forecast were confirmed. Moreover, the weather data management system was built. On(2), the ship's performance estimation algorithm of each ship by abstract logbook analysis and a performance model was developed, and practicality was confirmed. On(3), realization of the optimal route calculation on global scales and verification of the calculation result were performed, and the feature of optimum route in some sea area was shown.
