The application of the reeled pipe method for deepwater pipelaying
In the development of the Tahoe prospect, Shell Oil Company, designed the flowlines to be dual 4 inch nominal lines to begin in 1,500 feet of water and laid to the Bud Platform in 273 feet of water. The flowlines were to be laid simultaneously since they were to be tied into previously laid flexible jumper lines. The flexible jumpers were retrieved, the rigid pipe welded to the ends and the flowlines laid utilizing the Reeled Pipe Method to Main Pass 252, the location of the Bud Platform, where conventional risers were installed to make the surface connection. This paper will describes the pipe laying techniques used for this project. Specifically, the improvements in stinger design to permit lower horizontal tension loads, the use of dual pipe reels to maximize productivity, and the advantages of laying from a DP vessel.
