A Study of Forecast Current Data and Observed Data by Coastal Vessels
海流予測値と船舶での海流観測値との比較検討
The National Maritime Research Institute has conducted the research and development on “the environmental friendly shipping support system for coastal vessels” supported by NEDO using actual cement tanker and RORO ship cooperate with ship’s owners. The present study describes a practical methodology on the ship’s log speed estimated by analyzing accumulated actual navigation data of coastal vessels. The estimated values are checked by the relative velocity with respect to water derived from propeller analysis using measured torque of propeller shaft. Comparison of the ship drift and numerical forecast of the surface current suggests that use of higher spatial-temporal resolution in forecasting improves the forecast skill.
