Service
Materials Selection and Corrosion Control
Full life-cycle materials selection, corrosion and erosion assessment, cathodic protection and failure investigation.
Our materials, welding and NDT engineers provide integrated, full life-cycle services, from concept and design through procurement, fabrication, installation and operation, and beyond the design life. They work closely with our integrity, subsea design and flow assurance teams to choose the most cost-effective materials and the means of protecting them against internal and external corrosion and environmental cracking.
We start with high-level materials screening at concept stage and develop the selection through FEED and detailed design, with procurement specifications for long-lead items such as corrosion-resistant alloys and clad or lined pipe. On your behalf we review welding, coating, forging, heat treatment, mechanical testing, NDT and final inspection procedures.
Our integrity and materials engineers also team up on failure investigations, focusing on fact-finding, data gathering and interpretation, and clear reporting.
