Investigation of Slugging

Vibrations was observed on an installation and an analysis was performed to determine the likelihood of fatigue failure. Team Stressman was sent measurements and video. The motion was due to slugging in the pipe. Based on this input we investigated dynamical stresses. These stresses were checked against DNVGL-RP-0005 fatigue curves, design life factors and stress

Subsea Manifold

Team Stressman has over the years been chosen to perform flexibility calculations of fast-track subsea manifolds for TechnipFMC.  Our responsibility was to verify the structural integrity of the piping and piping components of the subsea manifolds. Subsea piping made of super duplex is exposed to hydrogen induced stress cracking (HISC). This complicates the pipe stress
