Overcoming the challenges of deeper subsea production

Sandvik Houston is strategically present to support and meet the customers’ challenges. “Our new Duplex materials will enable even longer seamless continuous subsea tiebacks as we continue to develop new, stronger, better corrosion resistance, enabling lighter materials in order to optimise the performance over many years,” concluded Mr Finzetto.

“We know the increasing demands that these deeper subsea oil and gas production requirements are placing on vital subsea tiebacks so it is important to extend the life of the production infrastructure,” said Leandro Finzetto of Sandvik. Sandvik seamless tubular materials for subsea tiebacks are installed in some of the most remote locations throughout the world, in challenging and demanding applications, helping turn deposits that were previously regarded as uneconomical into cost- effective reality.

“We help you get there” was Sandvik’s theme at the Subsea Tieback Forum, held in New Orleans, Louisiana, USA, recently in March. Examples of the company’s corrosion- resistant alloys and other high performance materials for tube, pipe, wire, welding consumables and powder-based hot isostatic pressed (HIP) components were on display. Subsea tiebacks – an increasingly important component of oil and gas production – facilitate linking new wells to existing production platforms. Specification, development and installation of the tiebacks have to be carefully considered in light of these more remote and deeper wells, which pose higher pressures and corrosion threats to the tiebacks themselves. During the material selection process, environmental conditions of the wellhead and the presence of corrosive elements such as hydrogen sulphide, chlorides and carbon dioxide are important to consider in achieving resistance to localised corrosion, particularly pitting, crevice corrosion and stress corrosion cracking.

Sandvik Materials Technology has invested significantly in setting up its global oil and gas team to work closer with its customers worldwide.
