A method of rotating a section of a pipeline about a longitudinal axis arranged coaxially with a bore of the section. The section includes a plurality of pipe elements joined to one another end to end. The section has a first end connected to the pipeline by a first coupling permitting rotation of the section relatively to the pipeline. The section has a second end connected to the pipeline by a second coupling permitting rotation of the section relatively to the pipeline. The method includes supporting the section at a plurality of points and applying a first torque to the section about the longitudinal axis at at least one point between the first and the second ends, thereby rotating the section through a first angular displacement about the longitudinal axis.

Method of rotating a pipeline section

A coupling for joining first and second pipe elements in includes first and second rings attachable to pipe elements. Each ring defines a groove and a plurality of receiving surfaces adjacent to the groove. Segments are attachable end to end to surround a central space and the rings. Each segment includes keys projecting toward the central space for engagement with each groove of the rings. Each segment includes at least one action surface engageable with a receiving surface of the first and second ring. Engagement between the action surfaces and the receiving surfaces prevents rotation of the first and second pipe elements with respect to one another. A method of assembling the coupling is also disclosed.
