Saipem Launches its New "Underwater Cold Bending" Technology for Sustainable Subsea Pipelaying

Saipem launches its new sustainable technology for subsea pipelaying which considerably reduces environmental impacts on the seabed. The "Underwater Cold Bending" technology was presented during the Offshore Technology Conference (OTC), one of the leading international events in the offshore energy sector.




The Underwater Cold Bending technology is a new subsea pipelaying method patented by Saipem which makes it possible to form vertical cold bends in the pipeline in a strictly controlled way and directly underwater by means of a specially designed remotely operated underwater bending machine. The fact that the bends are created when the pipeline is about to be positioned on the seabed means there is no interruption to regular pipelaying operations. This innovative technology optimizes the pipelay process in correspondence of sharp slopes or escarpments, where the site conditions are typically so critical as to present serious design concerns and which require massive seabed preparation works with heavy environmental impacts.

Compared to the traditional approach, the Underwater Cold Bending method represents a safe, sustainable and economic solution and guarantees the maximum integrity and safety of the pipeline throughout its life cycle.
