About this event

Reeling is a fast, reliable and cost effective method for installing subsea pipeline (flowline) systems up to 20-inch in diameter. The individual pipe joints are lined up and welded together onshore to make long stalks of pipes before being spooled onto the large reels of reel lay vessels. On arrival in the field offshore, it is spooled off, straightened and laid on the seabed much faster than conventional S-lay or J-lay pipelaying methods.

The ability to carry out the fabrication and welding onshore, off-line from the vessel critical path, allows much greater flexibility in schedule, ease in management of changes and high quality welding / coating to be achieved.

Over the last few years, it is evident that the engineering fundamentals and cost effectiveness of the reeling process are well understood within different sectors of the offshore industry as all major pipelaying Contractors own a reel lay vessel. The missing part of the puzzle, however, is the implications and practical aspects of the reeling process when it comes to project execution.

This presentation will review the engineering fundamentals of the reeling process first and then discusses the practical aspects and applications of reeling mechanics from fabrication to installation.
