| 摘 要： | 为了确保海洋立管的安全可靠运行,需要对其进行安全评估.选取我国渤海中某平台上实际运行的海洋立管为目标立管,根据我国海洋工程中承压管道的实际情况,采用我国安全评定标准,对给定参数的立管进行了安全评定.结果表明:计算得到该含凹坑缺陷海洋立管在海流载荷和波浪载荷共同作用下的安全系数为0.020 2,远小于规定值0.44,该立管是安全的,并具有一定的安全裕度.

| Abstract: | In order to ensure the marine riser safe and reliable operation,it needs to conduct a security as- sessment. In this paper choose a marine riser located in Bohai Sea as the target riser which is actually run- ning on a platform. According to the actual situation of riser and China＇s security assessment standards GB/T 19624-2004,the riser of a given parameter was evaluated. Then calculated the safety factor of riser with pit defects under currents and wave loads, the factor is 0. 020 2, it far les than 0.44, so the riser is safe,and has a certain safety margin. |
