Subsea 7 selected Vallourec for the tie-back of 7 subsea wells to the King’s Quay semi-sub, located in the Gulf of Mexico and operated by Murphy Exploration & Production Company – USA. The scope included 60km of 6” and 16” flowlines and Steel Catenary Risers (SCRs).

The project required heavy wall pipes, with wall thickness over 25mm, and stringent pipe-end tolerances installed by reel-lay method in water depths reaching over 1,000m. In addition to this technical challenge, the project was executed amidst Covid-19 restrictions, requiring reinforced HSE standards.

Vallourec’s technical expertise in the manufacturing of seamless pipes and its close proximity to EPCI companies and operators around the world, allows us to offer integrated, innovative, and cost-effective solutions for the most challenging deep-water projects. Vallourec delivered 60km of 6” and 16” flowlines and Steel Catenary Risers (SCRs) to Subsea 7 for the tie-back of 7 wells in the Gulf of Mexico.

The manufacturing of these heavy-wall pipes was possible thanks to the expertise of our two production hubs in Brazil and Germany, using end-truing solutions in order to meet stringent pipe-end tolerances. In addition, Vallourec’s project team1 also proposed its Smartengo Pipe Navigator solution which centralizes pipeline data to improve asset management and operational efficiency.
