A Case Study: Piecewise vs. Holistic Pipeline AC Mitigation Design

Picture for A Case Study: Piecewise vs. Holistic Pipeline AC Mitigation Design
Available for download

AC interference analyses are an important part of designing an adequate cathodic protection system on a pipeline when collocations with high voltage powerline(s) occur. Modeling software has been developed to create accurate simulations of what is occurring in the real world to create the best mitigation designs for operators. Many of these studies are proposed due to pipeline replacements that update pipelines from coatings with coal tar to fusion bonded epoxy (FBE).

An AC interference study and mitigation design was performed for a pipe replacement project. The project was broken up into multiple phases due to a construction schedule that spans multiple years. This paper is a case study examining the process of performing a piece-wise vs a holistic mitigation design for the pipeline. Designs are based on field data and software modeling. Designs for each approach are compared and their differences and benefits are explored.

Comparing AC Study Techniques In Addressing AC Corrosion Risk

Product Number: 51322-17735-SG

$20.00

AC interference studies have become increasingly popular in an industry where shared right of ways have increased and there has been a better understanding of how AC interacts between pipelines and powerlines that are collocated with each other. While modeling software for AC interference studies have been developed since the 1990s, advancement in AC interference processes have occurred as more has been learned over the years. When performing an AC interference study there are three steps that need to be completed: field data collection, modeling, and mitigation design. Within this paper, we can compare a project from ten years ago to a project from today to understand the developments that have been made over the course of time to improve the way we develop our mitigation designs.

"Mold And Mildew Investigation and Testing of Navy Interior Coatings"

Product Number: 51323-18804-SG

Mold and mildew growth within Navy ships is a significant issue across the fleet. To investigate this issue the Environmental Security Technology Certification Program (ESTCP) and the Strategic Environmental
Research and Development Program (SERDP) funded an investigation into the prevalence of mold in the fleet, with the end goal of developing solutions to remediate and prevent future mold growth. Thus
far, mold and coating data was collected from 26 ships across 6 geographic locations. These mold samples have been analyzed to determine the most common species and highlight those that are toxigenic. 
Potential Theory Applied to Cathodic Protection Design

Potential Theory Applied to Cathodic Protection Design

Product Number: 37652-POD
ISBN: 978-1-57590-395-8
Author: Rogelio De Las Casas and Ronald Bianchetti
$138.00

This is a print-on-demand (POD) book that will be produced just for you in 2-5 days after your order. It should arrive at your door in about one to two weeks. However, due to supply chain and logistic challenges currently affecting the industry, it may take longer. Allow three weeks for international orders.

Potential Theory Applied to Cathodic Protection Design provides the mathematical development of analytical equations for the design of cathodic protection (CP) systems for underground structures with anode groundbeds having various configurations. Equations include calculations for the resistance and voltage (potential) and will assist the CP design engineer.
