Forensic investigation

DNV GL, as an independent foundation, is recognized for its thorough and fully transparent failure investigations.  From major breakdowns to minor damage of individual components, our advanced laboratory testing and failure investigations provide our clients with valuable insight as to how components fail, and why.  

DNV GL provides the expertise and experience you need when components fail.    Our extensive experience includes numerous high-profile failure analyses across state, provincial and federal jurisdictions.

We provide material testing and qualification for both metallic and non-metallic components.  Degradation and failure mechanisms/modes regularly encountered include:

  • Fatigue / Corrosion fatigue
  •      Creep

  • Environmentally assisted cracking (SCC, HIC, SSC)
  • Localized corrosion pitting
  • Oxygen concentration cell corrosion
  • Microbiologically influenced corrosion (MIC)
  • Effects of harsh environments and mediums (H2S, NH3, etc.)
  • Mechanical damage
  • Thermal and chemical degradation of gaskets and seals
  • Explosive decompression of gaskets and seals
Some of the technologies and methodologies utilized in our material testing:
  • Optical microscopy
  • 3D microscopy and laser scanning
  • Scanning electron microscopy (SEM)
  • Energy dispersive spectroscopy (EDS)
  • X-ray diffraction (XRD)
  • Raman spectroscopy
  • Fourier transform infrared (FTIR) spectroscopy
  • Differential scanning calorimetry (DSC)
  • Gas chromatography / Mass spectrometry
  • Bacterial testing (serial dilutions, epiflourescent microscopy)
  • Tensile testing
  • Charpy V-notch impact testing
  • Burst pressure calculations (CorLASTM, RSTRENGTM)
