| Abstract: | Submarine pipeline is one of the important facilities for offshore oil field development. It is very important to make a fracture safety assessment to it. In this paper, the application of failure assessment diagram (FAD) technolo gy and the fracture safety assessment of three grades included in the standard B S 7910: 1999 are introduced in detail. An assessment system for welding repair o f submarine pipeline is presented and it can be used to make a fracture assess t o the flawed pipeline under stress and obtain the maximum length of the flaw in pipeline oriented circumferentially. This assessment system has filled in a gap of the fracture assessment software of submarine pipelines in our country. |
