| Abstract |
|
Existing GM estimation methods based on roll period have limitations in accurately determining roll periods during ship turns due to persistent outward inclinations. This study proposes a novel stability calculation method specifically designed for turning scenarios. To achieve this, centripetal force was calculated using GPS data from the ship, and a multiple linear regression model was developed to predict roll angles influenced by centripetal force. An anomaly detection methodology was then applied to assess stability by comparing the actual roll angles with the model's predicted values. Statistical techniques were utilized to establish threshold values for anomaly identification, providing criteria for stability evaluation. To verify the reliability and applicability of this approach, comprehensive validation was conducted using both real-world operational data and simulation data. This method aims to significantly enhance early detection of potential risks during ship operations and support effective responses. |
