Improved Performance

  • Pinholes of 1 mm (0.04 in.)

and less in diameter

  • Preferential girth weld

Improved Performance

  • AutoDataTM
  • Deploys machine-learning, adaptive algorithms that

are calibrated using high-resolution 3D laser scans of real pipe defects. This means that the evaluation algorithms continuously evolve during their application and therefore constantly improve the quality of their results, leading to a significant increase in defect sizing accuracy.

  • Large amounts of data are processed automatically

within seconds, leading to a significant increase in integrity assessment accuracy.

ATEX

  • The ATEX directive consists of two EU

directives describing what equipment and work environment is allowed in an environment with an explosive atmosphere. ATEX derives its name from the French title of the 94/9/EC directive: Appareils destinés à être utilisés en ATmosphères EXplosibles.

  • Directive 2014/34/EU – new ATEX directive
  • Increasingly required for ILI tools worldwide

New Developments and Operators’ Needs

What is worth pursuing?

  • Sensitivity
  • Accuracy
  • Reliability
  • Ease of operation
  • Specific defect types
  • Combination of defect types
  • Operational challenges/convenience
  • Affordability (price)
  • What else?

3.5 Integrity Assessment of Unpiggable Pipelines

slide-9
SLIDE 9

What is a Challenging Pipeline?

  • Pipeline which can not readily be pigged
  • Unpiggable, difficult to pig
  • Reasons for being challenging

– Design parameters – Operational parameters – Limited understanding (?)

  • Can they be made piggable?

– Priority – Budgetary constraints

slide-10
SLIDE 10

Causes of Unpiggability

  • Internal bore

– Multi diameter – Small diameters with tight bends – Valve design and size – Wall thickness

  • Pipeline materials

– Steel type – Weld type – Coatings

  • Bends and connections

– Tight (short radius) bends, back-to-back – Mitre bends – Unbarred tees – Y connections

10

slide-11
SLIDE 11

Causes of Unpiggability

  • Construction information not available
  • Operating conditions

– Fluid characteristics – Pressure, temperature – Low or no flow – Cleanliness of pipe – Disposal of added fluids (water)

  • Access

– No launchers and receivers – Plug valves, dead ends, offtakes

  • Installations

– With obstructions

Considerations

  • Pipe modifications

– Feasibility – Cost

  • Inspection coverage

– Quality – Reliability

  • Level of risk and safety

14

slide-15
SLIDE 15

Considerations

  • Need/convenience of repeated inspections

– Cost of modifications vs. increased cost of specially designed ILI tools to overcome pigabbility restrictions – Convenience of using readily available ILI solutions

  • Timeline/urgency

– Modifications – Potential ILI tool development

Planning for Unpiggable ILI

  • Standard ILI

– Fast preparation and execution

  • ILI of challenging lines

– Emphasis on strategy and tool development and pipeline preparation

  • Cleaning probably

also challenging

– Case specific

Cleanliness and Cleaning

  • Requirement for inspection
  • Restrictions for ILI might impede cleaning as

well

  • Case specific

– Type of debris – Restrictions/configuration – Launching/receiving traps – dead ends – Disposal – Choice of cleaning type restricted as a result

Tools for Challenging Pipelines

Tools readily available for some sections previously considered unpiggable

  • Low (high) pressure

e.g. 1/3 lower

  • Multi-diameter

e.g 36”/48”

  • Bidirectional (Bi-Di)

e.g. no receivers

  • Tight bend capability

e.g. 1 D

  • Short tools

short launchers/receivers

  • Effects of bend radii on maximum tool length in 90° bends
  • Sensor coverage and resolution

in changing pipe diameters

  • Back-to-back bends: challenge

for pull module

  • Mitre bends add loads to

detection unit

  • Unbarred tees in multi diameter lines:

challenge to geometry tool sensor arms

  • Low pressure: friction, speed stability,

speed of diameter adaptation, to minimize stoppage in ID reductions
