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.

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

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

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)

Inspection process.

Weld features.

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)

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

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

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 !

Introducing AugaTM

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

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

Introducing WeldAnalysis software

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.

WeldAnalysis interface.

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

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

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!
