摘　　要：参考采用锚泊移位系统铺管船的实际作业情况,利用Ansys-AQWA软件评估不同海况、不同布锚方式下铺管船作业的安全性,得出风流系数的计算公式,利用Fortran语言和批处理语句实现大量工况的自动计算和结果后处理。以一例布锚方式为例说明整套流程的实用性以及高效性,表明该流程可显著提高铺管船作业安全性评估的工作效率。Using the actual operation situation of pipe-laying vessel for reference, the Ansys-AQWA was used for assessing pipe-laying vessel＇s working security in different sea conditions and mooring layouts. A reasonable formula was presented to calculate the wind and current coefficients. Fortran language and batch statement were used for accomplishing automatic calculation of a large number of sea conditions and post-processing of the numerical results. One example showed that the process is practical and effective, improving remarkably the efficiency in the working security assessment of pipe-laying vessel.
