Leading engineering, construction & services company serving the offshore energy industry Subsea 7 has selected seamless pipes leader 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 60 kilometers of 6 inches & 16 inches flowlines and Steel Catenary Risers. 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 1,000 meters. 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 it to offer integrated, innovative, and cost-effective solutions for the most challenging deep-water projects.The manufacturing of these heavy-wall pipes was due to the expertise of Vallourec’s 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.
