FMC, Shell introduce new hydraulic tubing connector system

Offshore staff

RIO DE JANEIRO – FMC Technologies Inc. (NYSE: FTI) has developed and patented a technology to replace the orbital welding process used to connect small bore hydraulic tubing used in subsea equipment.

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.

FMC Technologies said it is pioneering its application underwater to address the problems of corrosion and susceptibility to hydrogen embrittlement.

The Shape Memory Alloy Subsea Fitting represents a cost and lead time reduction when compared with the orbital welding process, FMC said, and simplifies and speeds assembly and inspection times.

The technology development was done in partnership with Shell Brazil.
