Vallourec has been awarded a contract by OneSubsea®, the subsea technologies, production, and processing systems division of Schlumberger, to supply 3000 m of upset riser joints equipped with VAM® TTR HW NA connection for the Bacalhau Project offshore Brazil.

The contract was awarded on behalf of Subsea Integration Alliance, a strategic global alliance between Subsea 7 and OneSubsea.

Discovered in 2012 and located 185 km from the coast, the Bacalhau field is at a water depth of 2050 m in the presalt Santos basin. The development will consist of 19 subsea wells tied back to one of the largest FPSOs in Brazil. The first oil is planned in 2024.

After a comprehensive design phase to meet the expectations of Bacalhau field operator Equinor, OneSubsea selected the Vallourec high-performance solution for the Open Water Intervention Riser System (OWIRS). This solution is based on seamless shaped steel pipes equipped with a special premium VAM® TTR HW NA connection to cope with fatigue conditions and the sea corrosive environment.

Vallourec PFP® tube mill in Aulnoye-Aymeries (North of France) will produce shaped pipes whose upset ends will also be threaded on site.

“We are very proud to have been selected by OneSubsea and Equinor for the Bacalhau project. Being selected for the supply of a demanding open water intervention riser system gives us an opportunity to prove that our shaped pipes are highly efficient and competitive. Our Aulnoye-Aymeries PFP tube mill has unique capabilities to manufacture reliable pipes with upset ends, optimized body weight and versatile options for VAM or customer-supplied connections” said Hubert Paris, Senior Vice President Europe/Africa.
