Welding Operations in Norway

3 730 welds are going to be produced at the Orkanger spoolbase

Serimax, a Vallourec subsidiary and leader for on and offshore welding solutions, has been awarded by Technip the welding pipeline scope for a major project in Norway. This milestone project marks the beginning of a new era for the company, as Technip and Serimax combine their expertise and deploy Serimax Welding Technology at Technip’s Spoolbases and onboard Technip’s S-lay vessels following the strategic partnership signed earlier this year. Thanks to this agreement, both companies have the unique opportunity to combine their expertise and deploy Serimax welding technology.

Production welding for the project is scheduled to start before the end of 2016, preceded by a welding quality procedure testing program in Orkanger. Production welding will include double-joint welding in Technip’s adjacent facility where 12m long tubes will be welded end to end. The resulting 24m long tubes will then be transferred to the mainline (ML) production workshop where they will be welded into pipestalks, ready for Spooling onto the Technip Reel-Lay vessel. Production welding will include 1865 double joint welds and 1865 mainline welds.

In order to satisfy the requirements of the customer and guarantee an optimum level of quality for the welds to be carried out, the Serimax teams based in Northern Europe have worked closely with the central functions from Serimax’s Welding Technology Centre (near Roissy Charles de Gaulle) on an R&D program and have used the advanced Saturnax-09 system.

Serimax and Technip announce strategic partnership

Serimax and Technip announce strategic partnership specific to Spoolbase and Reel Lay only. This strategic partnership, which is subject to regulatory approvals, will include exclusive arrangements in the Reel-lay welding pipeline segment as well as research and development (R&D) related programs. Serimax will remain an independent service and technology provider, and will continue to serve its clients in the offshore, onshore pipeline and fabrication markets. To find out more about this strategic partnership click here
