摘　　要：开发了动力定位浮托安装法时域模拟工具,对某浮托安装船在动力定位方法下的待命就位过程进行了时域模拟研究。通过构建时域模拟模型,对该浮托安装船在各种海洋环境下的待命就位工况进行分析,得到该浮托安装船的位置偏移与消耗功率的时历与统计值。时域数值模拟的结果表明,该动力定位浮托安装船能够在180°和0°环境载荷作用下实现较为理想的待命就位,且在180°环境载荷作用下待命就位时,能避免驳船的推进器倒车,取得更好的定位精度和较小的功率消耗,是最佳的待命就位方向。该时域模拟的结果与分析,为实际的海上实船安装提供必要的理论与实践指导。Dynamic positioning assisted float-over installation can largely reduce the price of installation depending on the self-propelled barge and its strong load capacity,thus is widely used in industry. Standby is an important preparing period before the float-over installation begins. Based on the measured position and power consumption during this period,it can be decided whether the installation begins or not. In this paper,a time domain simulation program is developed to investigate the standby period of the float-over installation. The simulation results indicate that the floatover barge can be dynamicly positioned under 180°and 0° environmental loads,and thus give a reference to the practical operation.
