Defect Assessment Providing expertise when unique situations arise CC Technologies and DNV (CCT/DNV) are now one company providing you with the expertise to determine the severity of anomalies or defects. Beyond Basics
Following a Failure
When unique situations arise, CCT/DNV has the expertise and capability to determine the severity of a defect, how to proceed and when it may reach a critical size. Specialized expertise using defect assessment methodologies can provide high-level answers to problems that arise on the pipeline. It can also provide the technical background to select and justify a repair method. We can perform a defect assessment at any time from initial detection to post failure.
CCT/DNV can determine the cause of a defect after a failure to help prevent repeat failures. We use destructive testing methods that expose the defect area, then determine its root cause. We can also determine the accuracy of non-destructive testing methods and/or in-line inspection surveys on your pipeline system.
Initial Defect Detection With the initial detection of an anomaly or defect, we can determine the remaining life under current operating conditions using a fitness-for-service assessment or a remaining strength analyses. Our expert staff is very familiar with state-of-the-art analyses, with several staff members involved in the creation and revision of industry leading assessment methods.
A Range of Defects CCT/DNV can analyze a complete range of anomalies or defects in pipelines. We have unique expertise in solving welding, pipe to soil interaction and interacting defect problems, stress corrosion cracking (SCC) and much more. We can help you evaluate metal loss, crack-like indications, deformations, wrinkle bends and manufacturing defects by considering burst pressures, local stresses and strains, material properties and fatigue levels, etc. We can conduct defect assessments that are accurate and applicable to your unique situation.
