Abstract
Mooring forces and their uniformity are important indexes used to ensure the safety of mooring systems. In this study, a process analysis for ship cable breaking accidents is conducted through numerical simulation based on OPTIMOOR to analyze the mooring conditions of a 300,000-ton very large ore carrier (VLOC) cable breaking accident under extreme windy weather. Numerical simulation of the cable force of the vessel mooring accident is performed by using the proposed method, which basically restores the cable breaking accident under the windy weather. On the basis of the accident analysis of the VLOC and the comparative test under the assumption, a reasonable conclusion is obtained by discussing mooring safety under two modes, namely, ‘preadjusting the cable’ and ‘not adjusting the cable’. The numerical simulation research methods and conclusions presented in this paper can provide reliable reference for ship engineering and Marine investigation.
