FRANCE  The 10-year long-term agreement between Vallourec and ExxonMobil Guyana began in 2022 with the Yellowtail project, Vallourec announced May 3.

The customer will utilize Vallourec’s line pipe products and its suite of digital solutions.

Yellowtail is a deepwater project based in the Stabroek Block, more than 100 miles off the coast of Guyana.

In 2022 Vallourec produced 20,000 tons of line pipe for the Yellowtail project, equivalent to 7,000 pipes and 400 accessories. Oil production for the Yellowtail project is expected to begin in 2025.

“To deliver timely, quality products for the Yellowtail project, we are leveraging our pipe mills in Jeceaba and Barreiro, Brazil,” said Renan Toussaint, line pipe project manager. “We can also draw on our R&D program to further ensure customer demands are met.”

Digital services

ExxonMobil Guyana is leveraging several Vallourec digitalized tools, including Smartengo Traceability and Pipe Navigator as well as Best Fit analysis.

"Smartengo Traceability offers unique product identification, tracking and reporting from mill to sub-supplier through an in-yard smartphone field app," Toussaint said. "This gives our customers greater transparency by extending Vallourec’s traceability beyond our borders and integrating our sub-contractor into the system."

Pipe Navigator is a portal that provides a web interface for centralized data and document storage. It is designed to strengthen and accelerates the quality review flow and give live access to the entire production process. ExxonMobil Guyana has included the use of Pipe Navigator on subsequent orders.

Finally, Best Fit identifies pipe compatibility for pipe fit-up for girth welding, providing full visibility on achievable misalignment (Hi-Lo). This tool allows the user to receive key information about pipe end tolerances and associated fit-up simulations for all possible pipe combination long before the start of operations. It allows them to better assess risks at an earlier stage and make decisions concerning critical sections such as fatigue-sensitive areas.
