Mechanically connected subsea pipelay system improves integrity and saves 25-45% compared with traditional methods
Welded subsea pipeline systems are used in most developments. Industry needs more time and cost-effective alternatives to improve economics and unlock reserves. The Technology Leadership Board (TLB) highlighted the need for technology to support uneconomic small pools, particularly in reducing the cost of subsea tiebacks NZTC supported this project with Cortez Subsea identifying solutions for the Tieback of the Future.
The Cortez Subsea patented Modular Pipelay System (MPS™) enables Zap-Lok™ and other mechanically connected pipe to be laid from a standard DP2 vessel. This flexible pipelay is adjustable in both width and length, and has no heat affected zones, avoiding the need for welding. The GMC Intelligently Connected Pipe (ICP™) is designed for deep water and ultra-deep water (including pre/post-salt projects).
The ICP™ offers faster make-up due to pre-manufactured components being transported to the field as completed pipe joints. Integrity is also increased using high-strength, fatigue and corrosion-resistant connections.
With faster make-up and improved integrity, this technology has the potential to reduce overall costs by between 25-45%.
The Cortez Subsea Modular Pipelay system is cheaper than traditional methods and can be used in both deep water and ultra-deep water and can be laid from a standard DP2 vessel.
With no spool base, there is the potential for reuse and further industry efficiency savings.
