Study on the Approval Criteria for Fishing Vessel Main Engine Power Control Based on Main Engine Power Calculation Methods

Abstract

This study examines the challenges of accurately reviewing and approving the main engine power of multipurpose motorized fishing vessels. It summarizes theoretical estimation methods and examines the impact of various power estimation techniques through example calculations. The effective power method was used to estimate main engine power, and the performance of the fitted equations and auditing methods was evaluated. The results show that there are significant differences in the accuracy of the different auditing methods, with differences as high as 45%. The error of the fitted equation method is below 15%, while the Japanese effective horsepower estimation method has the smallest error of about 10%.
