摘　　要：随着国内外优质海岸线的减少和新建港口的海况愈发恶劣,给施工船舶水上施工作业带来了极大的挑战。为探索恶劣海况下的船舶海上施工,以3850 DWT甲板驳船为研究对象,考虑缆绳动力学,应用时域分析模块建立系泊分析模型,分析了船舶摆位、系泊形式、系泊半径、系泊角度和系泊点数对甲板驳船运动响应及缆绳张力的影响。分析结果表明,系泊系统对甲板驳船运动响应和缆绳张力影响较大,增加系泊半径、系泊张开角和系泊点数能有效减小船体运动响应和系泊缆力,可为船舶海上施工作业方案提供参考。As the reduction of high-quality coastline at home and abroad and the worse sea conditions of new ports,which brings great challenges to the marine construction operations of ships.In order to explore the marine construction of ships under harsh sea conditions,based on a 3850 DWT deck barge,considering cable dynamics,a mooring analysis model was and established by using time domain module,and the influence of ship positioning,mooring form,mooring radius,mooring angle,and mooring points on the motion response and cable tension of deck barge were analyzed.The analysis shows that the mooring system has a significant influence on the motion response and cable tension of deck barge,increasing mooring radius,mooring open angle and mooring points can effectively reduce motion response and mooring cable tension,which can provide reference for marine construction operations of ships.
