Question 1

What is the TPA – EA Reporting Hub?

Accepted Answer

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.

Question 2

What is the TPA - EA Reporting Hub workflow process?

Accepted Answer

The TPA – Engineering Assessment (EA) Reporting Hub is an end-to-end digital workflow that streamlines the creation of engineering reports for pipeline reactivation, discontinuation, or integrity validation.

The process begins with Form 1, where users enter their contact and company information.

In Form 2 - Pipeline Selection, the user defines the pipeline to be assessed by providing the Province, License Number, and Line Number. Upon submission of Form 2, a Power Automate workflow is triggered, which connects directly to the TRIAGE / AbaData risk model database via an API connection—retrieving pipeline metadata, corrosion risk factors, and integrity performance scores.

Next, the user completes Form 3, which defines the Scope-of-Work. This includes confirming the selected pipeline, specifying the EA Report type (e.g., Routine Reactivation, Discontinuation, etc.), and entering or verifying technical data such as diameter, material, status, MAOP, protection type, CP history, and inspection results. The collected data is used to support risk modeling and inform regulatory compliance.

Finally, Form 4 captures Order Confirmation and initiates the report generation process. Using the pipeline inputs and TRIAGE risk outputs, a TPA - EA Report / ChatGPT Language Model generates a preliminary EA Report that includes an internal/external corrosion assessment, mitigation plan, regulatory compliance review (e.g., CSA Z662 Clause 10.3.2), and a suitability-for-service statement. The report is made available in a Canvas interface for review and finalization by TPA.

Upon review and approval, TPA publishes the final EA Report in PDF format and transmits the report within two workdays following Order Confirmation.

Following publication of the final EA Report, TPA will submit an Invoice as per the details provided within the Form 4 - Order Confirmation.

Question 3

What are the classifications of EA Reports?

Accepted Answer

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:

1.	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.

2.	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.

3.	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.

Question 4

Do the TPA - EA Reports comply with regulatory requirements?

Accepted Answer

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

Question 5

What are the specific elements of TPA - EA Reports that comply with CSA Z662?

Accepted Answer

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.)

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.
