基于AQWA软件的码头系泊船舶缆绳断裂响应分析
Dynamic Response Analysis of Mooring Cable Breakage for Docked Ships Using AQWA Software
摘要
Abstract
To investigate the impact of the cable breakage on the motion response of a ship's mooring system,this study establishes a ship-berth mooring model based on the AQWA hydrodynamic analysis software.First,in the frequency-domain analysis,the six-degree-of-freedom Response Amplitude Oper-ators(RAOs)of the ship are calculated,revealing significant resonance peaks for roll and pitch motions within the range of 0.4～0.6 rad/s.Then,in the time-domain analysis,the C5C6 cable group subjected to the highest load under severe sea conditions(wind scale 7,wave height 2.5 m)are taken as the re-search object.The motion response of the mooring system is simulated under two scenarios:the cable breakage due to its own damage and the cable breakage caused by exceeding the Minimum Breaking Load(MBL;1 500 kN).The results show that both breakage cases lead to a significant increase in surge mo-tion(with velocity increments of 2.1 and 6.5 mm/s,respectively),raise tension in the remaining cables by 32%～45%,and increase fender pressure by more than 36%.In particular,a chain reaction of suc-cessive failures of adjacent cables is observed within 10 minutes after the initial breakage.The findings can provide references for mooring safety,mooring system design,and emergency response during bert-hing operations.关键词
