Abstract
The invention involves working on a pipeline which is subject to movements relative to a base such as ground, the deck of a floating barge, and the like. A rollable scaffold is frictionally coupled to the pipeline so that workers carried by the scaffold can move relative to the base and, therefore, become stationary relative to the pipeline. The scaffold carries a lift means for raising and lowering a pipe support positionable under the pipeline. The scaffold therefore allows the workers to work on the pipeline without being disturbed by the relative movements between the pipeline and the base.
