Abstract

Abstract: In order to quantify the influence of port meteorological factors on sail of ships, an effective model of ship navigation restriction was established based on fuzzy comprehensive evaluation. The navigation influence was comprehensively assessed under different meteorological conditions. The influences of wind, fog, thunder and rainfall on sail were studied, and the calculation results were compared with the test results. The results show that the fitting degree between the calculation results and the test results is 85%. The navigation restriction model conforms to the requirements of engineering application. The influence of wind, fog and thunder on sail is gradually enhanced. When the wind force is less than 6, the influence factors of fog and thunder can reach 0.31 and 0.24.
