摘　　要：针对大型导管架装载于驳船上进行的拖航,综合考虑拖航期间驳船的完整稳性、船体总纵强度、导管架的绑扎强度、支撑结构强度,以拖航运输某大型导管架为例,根据导管架的参数选择合适尺度的驳船,采用中国船级的Compass软件计算分析驳船的完整稳性及总纵强度,采用海上拖航指南中的公式校核导管架的绑扎强度,采用MSC.Patran/Nastran计算分析支撑结构强度,结果表明,相关措施满足法规、规范、指南的相关要求,可确保拖航期间导管架和驳船的安全。The towing safety of large jacket platform by using barge needs to consider comprehensively the intact stability of barge,the longitudinal strength of hull,the binding strength of jacket and the strength of supporting structure.Taking the towing of a large jacket as an example,appropriate size of barge was selected according to the size of the jacket.The intact stability and the longitudinal strength of the barge were assessed by Compass software of china classification society.The jacket binding strength was assessed by the formula in the Offshore Towing Guide.And the strength of the supporting structure was directly analyzed by MSC.Patran/Nastran.The results showed that the above safety indexes meet the relevant requirements of regulations,specifications and guidelines,which can ensure the safety of jacket and barge during towing.
