Product Number: 51317--9506-SG

ISBN: 9506 2017 CP

Author: Davie Peguero

Publication Date: 2017

$20.00

Pressure cycling and ultimate failure pressure testing was conducted on various pipe samples to verify the design formulas meet the specifications and are correct for use in design of field repairs. Results show that use of strain-based design methodologies for composite repair systems is suitable and effective.

Case Study - DC Potential Influence Investigation via Waveform Analysis

Product Number: 51324-21149-SG

Author: Marc Blouin; Darrell Cornet

Publication Date: 2024

$40.00

While conducting overline surveys including Close Interval Survey (CIS), Alternating Current Voltage Gradient (ACVG), Direct Current Voltage Gradient (DCVG), Alternating Current Current Attenuation (ACCA) and Depth of Cover (DoC) in the Southeast Saskatchewan, Canada, a section of the cross Canada/US border Alliance pipeline, an unexpected CIS potential was encountered whereby potential measurements dipped, falling below the -850mV potential criteria, before rising again back into the range before the drop. The location of the potential drop occurred at a foreign crossing thus stray current was initially suspected. The field crew remained nearby while the foreign crossing owner representatives were notified of a possible interaction requiring further investigation. An interruption and influence analysis plan was put together to determine the nature of the influence on the Alliance DC Potential measurement circuit. This paper summarizes the preliminary analysis and test plan, the field measurements, and results.

Case Study - Sharing An AC Mitigation System

Product Number: 51322-17786-SG

Author: Hycem Bahgat

Publication Date: 2022

$20.00

AC interference analysis between high voltage AC (HVAC) powerlines and buried pipelines is a matter of current interest due to the growing number of right-of-ways shared between powerline and pipeline infrastructure. This is only expected to increase as the worldwide energy demand grows considerably over the next 30 years,¹ and stricter environmental regulations and policies are applied. Therefore, AC interference will continue to be an issue of concern for powerline and pipeline operators to protect the public, environment, and maintain asset integrity.

Case Study: Integrated External Corrosion Management for A 12-Inch Crude Oil Pipeline

Product Number: 51323-18970-SG

Author: Keith Parker, Trey Johnston, Christophe Baeté, Michael Snow

Publication Date: 2023

$20.00

The Enbridge External Corrosion Prevention team (ECP) is developing an Integrated External Corrosion Management (IECM) process by which management of external corrosion control systems can be optimized while
maintaining asset integrity and safety. IECM is intended to provide a methodology by which operators can move from a traditional reactive approach to a state-of-the-art proactive strategy commensurate with industry expertise and technology. Here we discuss a case study intended to demonstrate and assess the outcomes of IECM. The subject is a 12-inch diameter crude oil pipeline located in North America. Results of the process reveal opportunities for improvement and efficiencies in operation and maintenance (O&M).

Cathodic Protection Optimization Using Integrated External Corrosion Management

Product Number: 51324-20917-SG

Author: Keith Parker; Trey Johnston; Christophe Baeté

Publication Date: 2024

$40.00

Monitoring and maintaining cathodic protection systems is a significant effort for operators each year. Annual survey locations are typically established at features such as casings and foreign pipeline crossings where abnormal operating conditions could result in elevated corrosion rates. Additional test stations are commonly located such that a maximum spacing is not exceeded and installed at locations of convenience, but it is unclear which test station locations provide meaningful data with respect to external corrosion risk. This paper reviews findings of a collection of case studies performed by the Integrated External Corrosion Management (IECM) team since 2021. Process improvements, assessment results, and high-level economic analysis for selected case study pipeline segments will be reviewed and discussed.
