Non-Destructive Evaluation Services
OSG can provide expert advice in the following areas:
- Most suitable inspection method (e.g. criticality of inspection, pipe and forging manufacturing requirements, girth welds for flowlines and steel catenary risers)
- Correct interpretation of data
- Verifying specification requirements have been met
- Setting up inspection plans
- Evaluation of performance of inspection equipment especially for critical application such as SCR’s and top tension risers (e.g., system qualification and verification)
- NDE requirements for pipe mill activities, including; selection of system, installation, qualification and commissioning
- Multi-probe systems vs. phased array systems
- Probability of detection
- Defect sizing accuracy
- Specifying AUT requirements for heavy wall thicknesses, in excess of 25mm
- Special requirements for SCR’s and top tension risers including wall thickness restrictions
- Use of time of flight diffraction (TOFD) to supplement shear wave inspection
- Third party verification offshore
