Quality Control Challenges • • • Historical documentation – Stationing listed (if any) may not match current GIS standards – Unsure if the document is the most current for that segment • Ex. HQ alignment sheets vs. redlines @ field offices – Filing structure isn’t conducive to limiting research to Class 3 & 4 and HCA’s • Organized by WO / AFE# Merging of GIS & Historical documentation – What is the source of the electronic data (GIS, risk, . xls, ILI, etc. )? – Historical takes precedence unless otherwise determined by operator (PHMSA ADB) – Terminology of documentation not matching GIS terminology • Ex. line identification – Line #2 South TX Jct. vs. Route Code 12345 Expertise of Document Review & QC Personnel – Natural trade-off’s between quantity, speed, quality & cost – Learning curve fairly steep, must be willing to invest in strong training & QC process – Frankly, the document review can be tedious; must let those who have mastered the document review to promote up to QC / other roles PROFESSIONAL ENGINEERS. REGULATORY EXPERTS. TRUSTED PARTNERS. www. rcp. com
Sustainability • Link source documents to MAOP data – GIS (PODS, APDM, other) – MAOP Data Books • Develop/improve MAOP procedures – Data capture – Data repository – Responsibilities • Don’t want to repeat this effort! PROFESSIONAL ENGINEERS. REGULATORY EXPERTS. TRUSTED PARTNERS. www. rcp. com
Discrepancy Resolution • PHMSA ADB 12 -06 – Annual report 3 -15 -2013 – Class 3 & 4 and HCAs in Class 1 & 2 • Gaps in source documentation – Poor quality document grades • Calculated MAOP < Established MAOP • Are there newer or higher quality source documents elsewhere? • Linear reference & stationing issues • Non-linear (distribution system) replacement projects – Old source document replaced with new one PROFESSIONAL ENGINEERS. REGULATORY EXPERTS. TRUSTED PARTNERS. www. rcp. com
Prioritize & Mitigate “Problem Segments” • What is PHMSA’s next step? • Hydrotest or other? • Schedule and priority? PROFESSIONAL ENGINEERS. REGULATORY EXPERTS. TRUSTED PARTNERS. www. rcp. com
www. prci. org 13 MVA vs ECA? § Because of a multiplicity of definitions, the project team proposed a new acronym § MVA (MAOP / MOP Verification analysis) § MVA in context to IVP § An MVA is an analysis, based on integrity management principles, of whether or not a given pipeline has sufficient safety margins under specified loading conditions (MOP/MAOP).
www. prci. org 14 PRCI PROJECT IM 1‐ 4 § The goal is to develop guidelines for conducting ECA’s § Flexible and practical § Based on integrity principles / best practices § Suitable for both hazardous liquids and natural gas § One time exercise to support MAOP / MOP § Leverage new and future technology developments § The pipeline industry believes that: § We have a substantial volume of information and experience. § As the daily practitioners of Integrity Management, we’re well suited to develop them.
www. prci. org Drivers for development 15 § Some lines/segments will be challenged to confirm IVP § Meeting Subpart E/J for hydro § Material properties and TVC § Pipelines pre‐dating regulatory code § New technology is evolving rapidly § MVA guidelines will leverage technology to facilitate effective regulation.
www. prci. org MVA Approach 16 § Identify all “parameters” subject to IVP § Identify each parameter’s relevancy to safety and integrity § Identify what integrity data can be used as a “substitute” for each parameter
www. prci. org 17 The Guidelines § Guidelines will be parameter specific and flexible for: § Different applicability of integrity threats § Different levels of relevancy for missing records § Differences in quality and quantity of supplemental records § Operational and Integrity history of the asset
www. prci. org MVA Approach 18 § Identify what technology and integrity processes are currently available and applicable to these substitutes § Identify what process and technology gaps currently exist and develop plan for filling these gaps § Develop parameter specific MVA guidelines (with options where possible).
www. prci. org IVP Parameters 19 § MAOP / MOP determination § Pressure Test Record requirements § Internal Design Pressure (IDP) material requirements • Test record examples • Test Charts • Test chart location & elevation • Test temperature • Instrument calibration • Description of facility • Responsible party • Et al. • Material documentation examples • Pipe Grade • Diameter • Wall Thickness • Seam Type
www. prci. org 20 MVA Process Flow
www. prci. org 21 Determine Relevancy § High Relevance – critical to determine MAOP / MOP § Examples include: Pipe Diameter, Wall Thickness, Test Pressure § Moderate Relevance – conservative assumptions applied § Examples include: Pipe grade, Seam type, Test station location § Low Relevance –little impact on MAOP / MOP § Examples include: Test Media, Test Date, Responsible Party signature
www. prci. org 22 Barrier Analysis § It is assumed barriers exist but may not be as robust when records are incomplete § Existing barriers can be reinforced or new barriers put in place § For each parameter, one or more sources of data (records, assessments or discrepancy analysis) will be identified that can analyzed and applied as a “substitute” for missing record information.
www. prci. org 23 Barrier Analysis § Requires threat analysis – substitute data will likely be threat specific § Focus will be on ILI data but will also include other testing data where applicable. § May identify that integrity data needs additional or different types of analysis than traditionally performed.
www. prci. org 24
www. prci. org 25 Process and technology gaps § Plans will be developed to fill identified gaps § Recent technological developments around determining material properties of pipe § In‐ditch methods for determining chemistry and physical properties § In‐line methods for identify pipe of similar properties § Processes need to be developed § Validation requirements, sampling protocols and confidence statistical analyses § Correlation of ILI data with in‐ditch data § Integration with other important data § Line Pipe Manufacturing History “Bible” § Construction and operational data § One‐off metallurgical analyses
www. prci. org 26 Example Scenario § No calibration certificate § This is required piece of documentation § This “parameter” has low relevancy § Could cause lower test pressure than targeted § Conservative assumptions can be made but: § What is expected / typical deviation? § What is most likely worst case? § Is MOP governed by pipe properties instead of test pressure? § If it was a 100% SMYS test, error in test chart pressure might have no impact on MOP
www. prci. org 27 Example Scenario § Utilize an ILI equivalency approach and existing IM practices § What is the remaining population of anomalies? § Repair to higher FPR? § Adjust ILI tolerance in anomaly analysis? § Guideline would recommend the following steps: § Determine appropriate potential gauge error § Compare this amount to current MOP and how it was established. § Adjust ILI response strategy (tolerance, dig criteria, repair level) to account for potential difference between actual and perceived test pressure.
