The oil and gas subsea industry is showing signs of optimism for the year ahead. Regions and countries like the Gulf Coast, Guyana, Suriname, and offshore Brazil are experiencing significant growth.
As the offshore industry goes further and deeper, operators are demanding higher-strength umbilicals that can withstand even higher pressures. Furthermore, they need cost-efficient solutions to ensure they remain within budgets.
That’s why we developed our new advanced material SAF™ 3007. It’s a safe, stronger, lighter, and more efficient alternative to SAF™ 2507, the industry standard we pioneered decades ago.
SAF™ 3007 is the latest addition to our growing duplex family, a super-duplex stainless steel grade especially developed for subsea umbilicals. It offers greater weight savings, thinner walls, reduced reel sizes which can reduce installation costs. It enables our customers to manage even higher pressures, access deeper wells, and handle longer tiebacks. Plus, it’s cost-effective per meter and just as welding friendly as SAF™ 2507.
Alleima at Subsea Tieback 2025
There was a lot of interest in SAF™ 3007 at the recent Subsea Tieback Forum and Exhibition held in Galveston, Texas. This year’s event exuded a vibrancy and momentum that suggested confidence in the sector is back and growing.
We displayed SAF™ 3007 alongside SA™ 2507 on our booth to highlight the compatibility of both grades. With its unique mechanical properties, SAF™ 2507 has been the preferred material for subsea umbilical tubing for many years, setting the global standard . However, for higher pressure, larger ID tubing, the relative lightness of SAF™ 3007 comes into its own. Its yield strength can be up to 15% greater than that of SAF™ 2507 depending on the tubing size. The chemical composition of SAF™ 3007 includes 30% chromium, molybdenum at 1% and, tungsten at 3.4%. Adding tungsten, maintains corrosion resistance after welding – a crucial feature for umbilical applications.
A critical component in project development is product lead times, and many end users who attended our booth were impressed with the material lead times that we offer. There was also a lot of interest in the corrosion and mechanical strengths of SA™ 3007 and the successful and rigorous testing we undertook to ensure market readiness for the most challenging conditions.
Sustainable steelmaking
SA™ 3007 is produced from 84% recycled steel, leading to a more sustainable result and lower cost per meter. Customers still enjoy the excellent corrosion resistance of SAF™ 2507, and a similar microstructure and weldability, but now benefit with reduced weight due to thinner wall thickness.
Forged from the past. Engineered for the future
This year’s Subsea Tieback highlighted a growing awareness of Alleima and our 160-year heritage in developing industry-leading advanced material technologies that empower our customers to be more profitable, efficient, and sustainable.
