Outline of Final Research Achievements

Nowadays due to the regulation of vessel's greenhouse gas emission, new built vessels need to install downsizing engines and existing vessel required to operate in low-speed which degrades the vessel's maneuverability. Therefore predicting full scale ship maneuverability becomes more strict than ever. However conventional maneuverability predictions are based on experiments using small model ship which could include some error between model scale and full scale maneuverability.
Therefore, in this research, computational fluid dynamics (CFD) using Reynolds-averaged Navier-Stokes (RANS) equation are applied to predict full scale maneuverability. The subject ship is tanker type vessel and full scale and model scale maneuvering simulations are conducted to clarify the scale effects on maneuverability.
