FMC Technologies, Inc. has developed and patented a technology to replace the orbital welding process used to connect small bore hydraulic tubing used in subsea equipment — the Shape Memory Alloy Subsea Fitting.

The technology is based on Shape Memory Alloys — a Nickel-Titanium material that returns to its original shape after subjected to environmental changes such as temperature or pressure. This same material is widely used in the automotive, aerospace and biomedical industries; however, FMC Technologies is pioneering its application underwater and solving the problems of corrosion and susceptibility to hydrogen embrittlement that can occur in a subsea environment.

The Shape Memory Alloy Subsea Fitting represents a significant cost and lead time reduction when compared with the orbital welding process. It dramatically simplifies and speeds up assembly and inspection times.

“FMC Technologies consistently pursues solutions to reduce costs and improve lead time with the highest safety and quality standards,” said Paulo Couto, Technology and Engineering Vice President at FMC Technologies Brazil. “We are excited about the Shape Memory Alloy Subsea Fitting and certain of its future widespread adoption and subsea application.”

The technology development was done in partnership with Shell Brazil, and has earned FMC Technologies a Spotlight on New Technology award – the first ever — at OTC Brazil 2015. The award recognizes extraordinary inventiveness within the E&P industry that contributes to the careful and efficient development of offshore resources.

FMC Technologies has full capabilities in Brazil, including technology development, engineering, manufacturing and services for subsea production and processing systems. Our regional operations include: two manufacturing facilities, and a Technology Center in Rio de Janeiro, and a service base in Macaé.
