Need: The Offshore Supervisory Committee of Pipeline Research Council International, Inc. has initiated a program to identify mechanical connectors which could be utilized in the J-Lay method of offshore pipeline construction. The J-Lay method offers advantages over the more conventional S-Lay method in deep water because the method imposes much lower stresses in the pipe during installation. It has the disadvantage that only one station is available for pipe joining, whereas in the S-Lay method 5-7 stations are available. The incentive for this project lies in finding a rapid joining method which overcomes the disadvantage of only one joining station.
Result: In this project, screening tests were developed to identify mechanical connectors suitable for use in the J-Lay method of offshore pipeline construction. A scope of work for the developing the screening tests was prepared by Sweet & Aiken, Inc., and is included in this report as Appendix 4 (PR-203-910). The J-Lay method offers advantages over the S-Lay method in deep water because it imposes much lower stresses on the pipe during installation. Two connectors each from four different manufacturers were tested with 8 5/8 inch O.D. , 0.438 inch wall thickness, API 5LX-52 pipe. All connections passed combined load tests (internal pressure, tension, bending, and torsion) without any problems or leaks.
Benefit: This report describes the results of the screening tests. The scope of testing was narrowed to four suppliers who volunteered samples for testing.
