The EA Reporting Hub is a secure, digital platform that guides pipeline operators through the Engineering Assessment (EA) process in compliance with CSA Z662. It automates data retrieval, streamlines data entry, and triggers the preparation of ready to submit EA Reports. The publication of the completed EA Report is transmitted in PDF format to the customer within 2 working days of Order Confirmation. The customer will be Invoiced for the order following deliver of the final EA Report(s) included on the Order.

TPA – Engineering Assessment (EA) Reporting Workflow 🔹 Step 1 – Pipeline Selection & Project Definition User selects a pipeline via Cognito Form #1: Inputs include Province, License Number, Line Number, and Report Type. Power Automate retrieves matching pipeline record from the PL_100_PIPELINE_DATA table (stored in Dataverse). 🔹 Step 2 – Auto-Populate Pipeline Details Power Automate dynamically generates a pre-filled URL to Cognito Form #2 ("Data Collection Form"). Pipeline metadata (status, diameter, MAOP, material, protection type, etc.) is automatically injected into Form #2 for review. 🔹 Step 3 – Data Collection & Risk Assessment Inputs The user completes Form #2 with key inputs for risk evaluation: Historical pigging, cleaning, ILI, and CP data Suspension details Mitigation measures Environmental sensitivities Upon submission, structured data is sent to Power Automate. 🔹 Step 4 – TRIAGE Risk Model Integration Data is mapped to the AbaData TRIAGE risk engine via an API connection, calculating: Internal Corrosion (IC) Risk Matrix External Corrosion (EC) Risk Matrix Remaining Life Failure Likelihood Water trap density CP performance scores Regionally normalized failure history is referenced for context. 🔹 Step 5 – EA Report Generation (ChatGPT + Canvas) ChatGPT generates the full Engineering Assessment Report based on: Pipeline metadata Risk profiles Environmental and operational constraints Regulatory obligations (CSA Z662 Clause 10.3.2 and AER directives) The report includes: Internal/external corrosion assessment Integrity verification plan Mitigation recommendations Suitability for service statement P.Eng. sign-off placeholder 🔹 Step 6 – Review & Export User reviews the EA Report in Canvas Final report can be exported to PDF or Word for: Internal approvals P.Eng. signature Submission to AER or other regulatory authorities

Here is a concise description to guide users of the TPA / Engineering Assessment (EA) Reporting Hub in determining the type of EA Report they need: Routine Pipeline Reactivation Applies to pipelines that were discontinued in compliance with regulations and are being returned to service with minimal modifications. Typically involves a review of historical integrity, compliance with regulatory requirements, and confirmation of operational readiness. Non-Routine Pipeline Reactivation Required when a pipeline has unique challenges, such as prolonged discontinuation, potential integrity concerns, or regulatory non-compliance. Includes detailed assessments of pipeline condition, historical performance, and additional mitigation strategies to ensure safe reactivation. Integrity Assessment / License Transfer Conducted when a pipeline is being transferred to a new license holder or undergoing an integrity verification process. Focuses on evaluating past operational history, failure records, corrosion risks, and mitigation strategies to ensure compliance and reliability before transfer or continued use. This description helps users quickly identify the appropriate EA Report based on their pipeline's status and regulatory requirements.

Regulatory & CSA Z662 Compliance Summary Trusted Pipeline Advisor (TPA) Engineering Assessment (EA) Reports are developed to meet or exceed the requirements outlined in: CSA Z662: Oil and Gas Pipeline Systems AER Directive 056 – Pipeline integrity requirements for reactivation, discontinuation, and abandonment AER Directive 077 – Requirements for pipeline performance and integrity evaluation Applicable jurisdictional expectations (AER, CER, BCER, etc.) TPA - EA Reports are: Fully structured in alignment with CSA Z662 Clause 10.3.2 Built to satisfy AER’s submission expectations Designed for transparency, traceability, and regulatory defensibility

Regulatory & CSA Z662 Compliance Summary Trusted Pipeline Advisor (TPA) Engineering Assessment (EA) Reports are developed to meet or exceed the requirements outlined in: CSA Z662: Oil and Gas Pipeline Systems AER Directive 056 – Pipeline integrity requirements for reactivation, discontinuation, and abandonment AER Directive 077 – Requirements for pipeline performance and integrity evaluation Applicable jurisdictional expectations (AER, CER, BCER, etc.) 🧩 Key Areas of Alignment 1. Engineering Assessment (EA) Purpose and Scope CSA Z662 Clause 10.3.1 & 10.3.2 require that EA reports justify the suitability of a pipeline for continued or new service. TPA EA Reports clearly define why the report is needed (e.g., non-routine reactivation), what pipeline is under review, and what decisions the report will inform. 2. Pipeline Description & Operating History TPA reports provide full design details, historical service, shutdown events, and operational pressures in alignment with CSA Z662 Clause 4.14 and AER Directive 056 reporting obligations. 3. Corrosion Risk Assessments Reports include detailed internal and external corrosion risk classification based on: Fluid chemistry Flow dynamics Environment Historical mitigation These are directly aligned with CSA Z662 Clause 10.3.2 (b, c, e). 4. Historical Integrity & Inspection Records Reports include a review of pigging, cleaning, ILI, CP performance, and inspection history, addressing CSA Z662 Clause 10.3.2(f). TPA’s integration with TRIAGE data enables strong evidence-based analysis. 5. Integrity Verification Planning Recommendations comply with CSA Z662 Clause 10.3.2(g): When hydrotests are not feasible, alternatives like in-service leak testing with enhanced leak detection are proposed and justified. 6. Environmental Risk & Consequence Analysis TPA includes consequence scoring and cost estimation consistent with industry norms and CSA Z662 Clause 10.3.2(i), particularly for environmentally sensitive areas. 7. Recommendations & Risk Mitigation Comprehensive risk-based mitigation strategies are proposed including: Chemical inhibition Enhanced CP evaluation Visual/NDE inspections Cleaning programs These follow the intent of CSA Z662 Clause 10.3.2(j) and AER integrity management expectations. 8. Professional Sign-Off Each EA report includes a placeholder for final review and authentication by a licensed Professional Engineer (P.Eng.), per CSA Z662 Clause 3.1.2 and regulatory engineering accountability requirements.
