A flowline bundle is twisted or braided into a permanent rope-like helical configuration, prior to laying the flowline bundle offshore by the reel method. Apparatus for forming the helical flowline bundle includes a pipe twist head and a series of pipe tumblers alternating with intermediate pipe supports, which apparatus rotates and translates part of a flowline bundle while simply translating the other part.
