Abstract
A method for securing a shell assembly to a pipeline. A two part shell assembly is secured to the pipeline and holds in position an annular sealing arrangement located about a predetermined area of the outer surface of the pipeline. The sealing arrangement includes a containment ring surrounding an annular seal. The containment ring is provided with connected through passages so that sealant can be introduced by a hole in the assembly into the passages to provide sealing between the containment ring and the pipeline, and between the containment ring and the shell assembly. Thus, should the annular seal fail during service the introduced sealant provides a seal.
