Publication number: 20230331347Abstract: [Problem] To provide a method for further reducing the friction resistance of a friction resistance reduced ship. [Solution] Rolling and pitching vary greatly depending on variations in climate, etc.; however, when limited to an extremely short time, the rolling and pitching repeat in an almost identical or similar pattern. Therefore, if the pattern of the immediately preceding rolling and pitching is understood, the subsequent pattern can also be predicted. This is similar for vertical position variation patterns of minute bubble generation units calculated from the angle of the rolling and pitching. Furthermore, the vertical position variation also differs depending on the installation position of each minute bubble generation unit, so the present invention measures the vertical position variation for each minute bubble generation unit, while also predicting the vertical position variation at and after the current time.Type: ApplicationFiled: March 12, 2021Publication date: October 19, 2023Inventor: Yoshiaki TAKAHASHI
