摘要：

A new technique for sub-sea pipeline repair involves the installation of a sleeve over the joint and performing a sub-sea, remotely-operated fillet weld between the pipe and each end of the sleeve. This paper concerns the burst limit state: the presence of the sleeve repair shall not reduce the pipe burst pressure. The results of a burst test conducted on a 42 '' sleeve-repaired pipe are presented and compared with FE-analysis. Good agreement between the test and the FE-analysis is found for the development of strains in the pipe and the sleeve, and for the pressure at which burst occurs. The presence of the sleeve does not influence the burst pressure.
