摘要
基于"浦东号"浮船坞的迁址改造工程,根据作业海域的水文气象条件,设计其12点锚泊定位系统。采用HYDROSTAR,建立浮船坞的水动力模型,考虑浅水效应,计算浮船坞的水动力性能、一阶波浪载荷及二阶差频波浪载荷(QTF);采用ARIANE,基于准动态理论,考虑船首右舷趸船的影响,建立浮船坞的系泊计算模型;计算浮船坞在高、低两种潮位下的运动响应及缆绳张力,调整缆绳长度及布置角度,优化系泊系统。计算表明,经过设计优化的系泊系统满足规范要求,适用于该作业海域。
Serving the relocation and reconstruction project of floating dock ＂Pu Dong＂,the 12-point mooring system was designed according to the hydrology and weather condition of the operating area.The hydrodynamic model was established by HYDROSTAR and taking into account the effect of shallow water,the hydrodynamic performance,1st and 2ndorder wave load were calculated.On the basis of quasi-dynamic analysis and considering the effect of the pontoon on the starboard,the mooring model was developed by ARIANE.The motion response and line tension were calculated in both high and low tide levels.Through adjusting the length and angel of the mooring line,the mooring system was optimized,resulting in the one totally satisfying the code requirement and adaptable to the operating area.
