Abstract
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.
