Abstract
A method for securing a branch assembly to a 'live' pipeline. An upper part of the assembly incorporating the branch is positioned on the pipeline over a containment ring located on the pipeline and within which is an annular seal surrounding an area from which the branch is to extend. A lower part of the assembly is positioned on the pipeline beneath the upper part and the two parts are secured together so that the seal is compressed and an annular space is left between the two parts and the external surface of the pipeline. Grout is injected into the annular space and cures to bond the two parts forming the branch assembly in position on the pipeline. The use of grout avoids having to use welding techniques on a 'live' pipeline. A coupon can be cut out of the pipeline, via the access through the branch.
