| Outline of Final Research Achievements |
A methodology estimating accurately service performance and encounter sea-state with the statistical analysis of voyage data measured by an on-board monitoring system has been developed. Voyage data are provided as sea-state, ship and engine motion, structural response and maneuvering information. A multivariate kernel regression model is applied as a statistical model. Shaft power, measured on a shaft connecting main engine and propeller, has been verified to be decomposed into a base power in still water, an added power in waves and an added power in wind. Sea-state has been verified to be estimated with structural response data.
