INTRODUCTION

The accurate identification and evaluation of a pipeline’s material properties and anomalies using non-destructive testing (NDT/NDE), advanced NDT and other specialist techniques plays a significant part in any integrity-management programme (IMP). The information and data collected is used to assist the owner/operator in avoiding unnecessary repairs and in evaluating anomalies characterised by ILI tool runs.

THE Applus+ SOLUTION
Applus+’s pipeline integrity assessment (PIA) services offer the on-site evaluation of pipeline anomalies in support of direct-assessment (DA) programmes, in-line inspection (ILI) validation programmes and class-change programmes undertaken by pipeline owners and operators. They involve specially developed inspection techniques, technologies and technician training which are designed specifically for thin-wall pipeline applications. 
 
The assurance of competency is key to a successful pipeline assessment. The practice of NDE requires certification that is controlled and governed by several managing entities. Applus+ ensures its competency in pipeline integrity assessment through a progressive and standardised training and certification programme. Much like the ASNT-TC-1A certification programme, the Applus+ programme is monitored to ensure a combination of in-depth theoretical training and field experience, followed by a rigorous written and practical examination.
 
The chief benefit of partnering with Applus+ for a pipeline integrity assessment is the extensive resources we can put at our clients’ disposal. Whatever the need of the client, be it code interpretation and compliance, inspection-data management or critical-feature assessment in the field using advanced NDT techniques, Applus+ is equipped with all the necessary resources, including:
 
  • Applus+ InSite – a field-reporting and data-management system
  • Engineering review and assessment capabilities
  • NDT3D IWEX – for the assessment of seam and pipe-body anomalies
  • 3D laser mapping – for external corrosion and ILI tool-data pattern matching
  • Material verification testing expertise
  • DTI Trekscan – for difficult-to-inspect pipelines
