LAYING THE WORLDS DEEPEST PIPELINE, LESSONS LEARNED

The paper addresses the success of the comparatively recent development of J-lay with respect to deep water pipelay. In laying the world's deepest rigid pipeline in Brazil, a tool was utilized which was built in 1979 when the flowline industry generally did not exist. The installation vessel, the reel vessel Stene Apache, did require modification to its pipelaying equipment and support services. These modifications were not radical and were part of an ongoing upgrade of capability based on requirement, i.e. market forces, to meet the needs of the day. To address the subject matter, it is necessary to mention that, until 1992, the deepest rigid pipeline was a 10 inch pipe at 705 meter depth. In 1994, the pipeline installed was a 12 inch pipe at a new record depth of 886 meters.
