VALLOUREC WINS A CONTRACT WITH ALLSEAS FOR ATAPU 2 OFFSHORE PROJECT IN BRAZIL

Meudon (France), on July 22, 2026 - Vallourec, a world leader in premium seamless tubular solutions, announces that it has been awarded a contract by Allseas for the supply of carbon steel seamless line pipes and thermal insulation coating for the Atapu 2 project developed by the Unitized ATAPU consortium operated by Petrobras.

This contract includes the supply of 143 km of rigid risers and flowlines, representing approximately 19,000 tons of bare line pipe.

The Unitized ATAPU consortium operated by Petrobras intends to develop a portion of the offshore Atapu Field, located in the Santos Basin, approximately 230km off the coast of Rio de Janeiro, at water depths ranging from 2,000m to 2,350m. The production system of the Atapu 2 field will be composed of 18 wells directly connected to the Floating Production Storage and Offloading (FPSO) through rigid risers.

The seamless line pipes will be produced in Vallourec's Jeceaba mill, while the associated thermal insulation coating will be carried out in Serra, building on the expertise and capabilities recently acquired by Vallourec to reinforce its premium coating offer and bring more value to customers.

Philippe Guillemot, Chairman of the Board of Directors and Chief Executive Officer commented: "We are proud to support Allseas and the Unitized ATAPU consortium operated by Petrobras on the complex Atapu 2 project. This contract is a perfect illustration of our strategy to provide integrated, high-value solutions for the most challenging environments. By combining our premium pipe manufacturing in Jeceaba with our thermal insulation coating capabilities following the acquisition of Thermotite do Brasil, we are able to offer a full-scope, streamlined and efficient supply chain, built on a strong local manufacturing footprint.
