OPS Direct Assessment Workshop

OPS Direct Assessment Research and Development Projects

James Merritt

R&D Program Manager,

Office of Pipeline Safety


November 4, 2003


OPS R&D effort stimulates economic activity, creates job opportunities and strengthens the industry’s competitive position in global markets.

OPS will match one-for-one industry’s R&D contribution to collaborative research. This will stretch industry’s research dollar and ensure OPS research priorities accurately reflect the sector’s real needs. Speed up the process of transferring new technology into the private sector.

New Standards and RulesDriving Recognition of R&D Needs

  • Need for Integrity Management Requirements Recognized

    • New Assessment Technologies Available

    • Ineffective Risk Data Integration Contributed to Major Incidents & Accidents

  • Development of Consensus Standards and Rules Highlighted Knowledge and Technology Gaps

Examples of IdentifiedGaps

  • Cost effective methods to Assess Pipes that cannot be Inspected using ILI

  • Improved Leak Detection over a wide range of Leak Rates

  • Ability to Real-Time Monitor Parameters affecting Pipe Integrity

  • Ability to Integrate Risk Factor Data

Continuing R&D Needsfor Direct Assessment

  • Validate ECDA Techniques

  • Validate Confirmatory Direct Assessment

  • Validate Application of ECDA for Detection of Mechanical Damage

  • Verify ICDA Consensus Standard

  • Develop and Validate Wet-Gas ICDA Process

  • Develop and Validate SCC DA Process

Recent R&D Projects


OPS co-funded DA R&Dactivities

Remote-Field Eddy Current to Inspection of Unpiggable Pipelines ($87,500) – SwRI

Long-range Ultrasonic Method for Detection of Degradation in Buried, Unpiggable Pipelines ($500,000) –PetroChem Insp.

ICDA of Gas Transmission, Gathering & Storage Systems($260,165) -SwRI

Improvements to ECDA Assessment Methodology by Incorporating Soils Data & Managing the Integrity of Early Transmission Pipelines ($297K) –Battelle Corporation

Develop high-amplitude guided wave for long range pipeline inspection ($272,420) -SwRI

Remote-Field Eddy Current toInspection of Unpiggable Pipelines

GOAL: Demonstrate a pipeline inspection method that:

Is sensitive to pipe wall thickness loss

Implemented into a ILI tool

Small enough or partially collapse to allow passage through internal restrictions


Technology Assessment

RFEC coil design

Breadboard system
