Brazilian independent operator Prio chose SAFTM 2507 super-duplex umbilical tubing for their operations in the deep-water Campos Basin. The proven strength of SAFTM 2507 and its ability to withstand high pressures were important considerations in its selection for the lengthy tieback.

Over 700 kilometers, or approximately 1,000 tons, of seamless stainless steel tubing, will be manufactured throughout the year for one of the longest subsea tiebacks on the Wahoo pre-salt oil field in Brazil.

The field’s subsea manifolds will be tied back to the floating production, storage, and offloading (FPSO) vessel on the neighboring Frade field approximately 35km away.

The lightweight and strong resistance to highly corrosive conditions of SAFTM 2507 has advanced the industry for over 30 years. It has been recognized as the industry’s leading material for umbilicals and is characterized by excellent resistance to stress corrosion cracking in chloride-bearing environments and to pitting and crevice corrosion. It has high resistance to general corrosion, erosion-corrosion, and corrosion fatigue, high mechanical strength, and good weldability.

“Umbilical tubes must be robust enough to allow the transmission of fluids and signals as quickly as possible. They must also be able to withstand localized mechanical and chemical corrosion and high pressures, which is why SAFTM 2507 is the industry’s material of choice for stainless steel umbilical tubing. For very long tiebacks, these challenges are even more demanding,” says Murilo Simoes, Applications Engineer, at Alleima.

“Supporting the Wahoo project has strategic importance for Alleima. In the Brazilian market, the number of new independent entrants alongside established companies is increasing. It is important to continue to extend support to them with our expertise and technical leadership in umbilical tubes production, allowing companies of all sizes to advance their operations quickly,” says Alan Souza, Regional Sales Manager.
