Corrosion technology center

Our capabilities and assessment methodologies enable the study of a variety of material threats. DNV maintains a highly skilled and experienced staff of materials scientists and engineers backed by one of the premier materials and corrosion technology centers in North America. We perform services for all aspects of component failure and failure response:

  • Onsite incident response
  • Forensic investigation
  • Component failure analysis
  • Incident root cause analysis
  • Litigation support
  • Regulatory support
  • Laboratory testing, modeling, simulation
  • Training.

Our scientists, engineers and subject matter experts provide unmatched technical expertise and practical experience. A systematic and detailed approach to material science is augmented by a full understanding and in-depth knowledge of applicable codes, standards, and regulations. We utilize cutting edge laboratory and modeling tools for determining asset/component fitness for service and, in the case of failure, the mechanism/mode and root cause of failure.

Sour service testing and more

We test both metallic and non-metallic materials, with specialties in harsh environments such as sour service testing and high pressure – high temperature (HPHT):

  • Qualification/selection
  • Capability for full suite of sour service tests per NACE MR0175 qualification requirements
  • Fatigue and fracture - fitness-for-service/remaining life/time-to-failure
  • Corrosion/crack growth rate
  • Coating and inhibitor performance, CUI
  • Probabilistic assessments and life prediction.

Degradation and failure mechanisms:

  • 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, including sour service testing (H2S and NH3)
  • Mechanical damage
  • Weld defects
  • Manufacturing defect
  • Thermal and chemical degradation of gaskets and seals
  • Explosive decompression of gaskets and seals.

Industries served:

  • Oil and gas
  • Power generation
  • Nuclear
  • Medical
  • Department of Defense.

Laboratory testing services include: 

  • 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, epifluorescent microscopy)
  • Burst pressure calculations (CorLAS™, RSTRENG™)
  • Range of test methods to characterize environmental degradation:
    • ASTM & NACE methods for materials qualification (ex.: ASTM G48, NACE TMO177)
    • Custom test methods to provide FFS solutions.
