OMS provides independent weld inspection services to the oil and gas industry using specialized tools like the WeldChecker and Auga. The WeldChecker uses cameras and lasers to inspect welds in pipes from 4-28 inches, while the Auga performs real-time 360 degree scans of root welds inside PLETs and attaches to the ILUC. OMS has over 40 employees, 10+ years of experience working with major clients globally, and their tools and analysis software help improve weld quality and productivity during pipeline construction.

8. Weld Inspection.
Weld inspection services are required to determine the various
features, attributes and potential defects of a weld within a
pipeline to determine it is fit for purpose and ensure integrity.

9. Why inspect?
Achieving superior weld joints is crucial to pipeline construction.
The integrity of a pipe joint hinges on the quality of a weld and
can help to avoid:
• Meet specifications
• Cut-outs and pipe repairs
• Unnecessary downtime
• Shortened lifespan
• Potential leaks and disasters

10. What to inspect.
More stringent safety requirements bring about the need for
more diligent inspection
• SCRs
• CRA clad welds
• Flowlines
• PLETs and PLEMs
• Clad welded pipe
• Carbon steel pipe
• Fatigue-critical pipes and structures
• Manifolds, forgings, spool pieces and bends

11. Weld inspection challenges.
• Stringent welding specifications, eg, CRA
• Welds located in difficult to access structures
• Early inspection is often preferred, eg, immediately after
the root and hot pass
• Inspection may have to occur on and offshore, both
horizontally (S Lay) and vertically (J Lay)

14. Inspection process.

15. Weld features.

16. WeldChecker: inspecting
• Power and data transfer via umbilical cable
• Rotary head allows 360 degree scanning of the weld
• High definition camera for visual inspection
• Various methods of deployment available, such as push
rods, winch/wire system, crawler units and attached to an
internal line up clamp (ILUC)

17. Crawler deployment.
We have created our own bespoke crawler units allowing
reliable and robust deployment of inspection tools
• Capable of withstanding harsh conditions
• Ability to reach 1,000 metres down a pipeline
• Capable of vertical crawling and traverse
complex pipe geometry

18. Capabilities
• Camera and laser inspection
• Pipe sizes: from 4” to 28”
• The only system in the world that can travel
around bends to inspect PLETs and PLEMs at 4”
• Vertical crawling deployment: visual and laser
• Camera inspection capable at 2”
• Inline weld inspection using the AugaTM

19. Case study.
Shell, Gumusut-Kakap
• Created laser and camera to inspect the root weld
within PLETs and PLEMs of 4” diameter around bends
• Inspection of root weld was written into project
specification
The client suggested to OMS that this
type of inspection wasn’t possible !

20. Introducing AugaTM

21. AugaTM
overview.
Real time verification in the firing line
• Attaches to the rear of the ILUC and performs a
complete 360° scan of the root pass in under 20 seconds
• Set predetermined tolerances and highlight areas out of
project specification
• Automatically locates the weld

22. Seamless integration.
• Records detailed pipe geometry and an accurate 3D
topographic map of the weld
• An Excel report is automatically generated highlighting
weld attributes
• Works in conjunction with WeldAnalysis software

23. Introducing WeldAnalysis software

24. WeldAnalysis overview.
Supporting Auga is a new version of OMS’
proprietary WeldAnalysis software.
This unique, powerful software processes data
from weld inspection tools, highlighting specific
features. This allows the operator to quickly
analyse and pass the weld.

25. WeldAnalysis interface.

26. Benefits of OMS weld inspection.
• Check root weld and geometry before further passes
• Reduction in cut-outs
• Rapid real-time full reporting with documentation
• Fewer defects at the AUT stage
• Improve overall productivity and efficiency
• CSWIP qualified operators

27. Recent projects.
• BG Knarr
• BP Andrews
• BP Quad 204
• BP Claire Ridge
• BP Laggan Tormore
• Deep Gulf Energy Kodiak
• Shell Cardamom
• Shell Princess III
• Total Laggan Tormore
• ExonMobil Point Thompson
• Shell CPID
• Shell Mars B

28. The Auga served the purpose very well …
exactly the tool required … SCR specs
normally allow up to 0.5mm miss-match
(HiLo) alignments ... the tool will be
recommended!
