QEM Solutions brought on board our specialist CP and Pipeline Integrity specialist (Dr Pat Lydon) to help us deliver a 4 day workshop in Georgia on the Direct and Indirect inspection techniques that can be used in Non-Piggable pipelines.
A three day seminar involving both theoretical and practical examples will provide the attendees with an understanding of which techniques, both direct and indirect are best suited to their individual instances of infrastructure.
The scope of activities presented during the 3 day seminar / demonstration will include:
-
Pre-Assessment
-
Gathering previous history & pipeline data
-
Risk Based Analysis
-
Review areas of High Risk
-
Select areas to be inspected with indirect inspection techniques
Indirect Inspection
-
Direct Current Voltage Gradient check (DCVG)
-
Alternating Current Voltage Gradient (ACVG)
-
Close Interval Potential Survey (CIPS)
-
Visual Survey of above ground pipe
-
Interpret results to highlight potential defect locations
-
Grade defects dependant on likely defect size and level of risk
Direct Inspection
-
Select locations to be investigated
-
Lower Pipeline Pressure
-
Locate suspected defect
-
Excavate pipeline
-
Measure coating damage and corrosion depth
-
Calculate remaining strength
-
Ascertain the root cause of the defect
Post Assessment
-
Analysing the info from direct inspection techniques
-
Reviewing future inspection requirements
The seminar was a huge success with QEM & IACS producing an informative conditional report for information after the event.
