PIPELINE ENTRY SYSTEM

摘要

An apparatus for inserting coiled tubing into a sub-sea pipeline comprising an adaptor which is releasably couplable to an anchor to hold the adaptor in position against lateral and/or vertical forces, the adaptor having: i) a first end comprising first coupling means for releasably coupling the adaptor to a riser and an opening through which coiled tubing can extend, ii) a second end comprising second coupling means for releasably coupling the adaptor to the anchor, and iii) a curved guide comprising an entrance end facing the opening and an exit end, the curved guide being in communication with the opening such that coiled tubing from the riser can extend through the opening and along the curved guide, the curved guide, in use, guiding the coiled tubing from a substantially vertical orientation at the entrance end to a substantially horizontal or near-horizontal orientation at the exit end.
