Abstract

Full Name :  Anand Kulkarni
Title / Position:  Director
Company:  Corrosion Control Services (B) Pvt. Ltd.


Mr. Anand Kulkarni is Trustee of NACE International Gateway India Section (NIGIS) for 2016-19. Earlier, he served the section in various capacities including that of Chairman during 2015-16. He was also a founding member of this section when it was formed in 1992.
 
An electrical engineer, he also holds a MBA degree from University of Michigan, USA.. Further, he is a ‘Cathodic Protection Specialist’ certified by NACE International as well as a NACE-accredited Cathodic Protection (CP) Instructor. He serves as a member of the CP subcommittee and the CP Review Board besides other CP related task and technology exchange groups of NACE International.
 
As Director of Corrosion Control Services, (B) Pvt. Ltd., Mr. Anand Kulkarni is responsible for the execution of onshore and offshore projects related to CP for oil, gas and petrochemical industries. His expertise and experience of 27 years in CP covers a range of applications including underground and offshore pipelines, plant piping, tank bottoms, jetty piles and other buried and submerged steel structures.
India has a pipeline network of almost 40,000 km. While most of these are cathodically protected, CP engineers have to increasingly contend with the challenges posed by electrical interference. The potential threats caused by electrical interference have increased significantly as multiple pipelines share a common right of way and even common corridors with high voltage AC overhead power lines. 
 
This presentation briefly discusses the common sources of AC and DC electrical interference that pose a threat for cathodically protected pipelines. The sources of DC interference include other CP systems, DC electrified traction systems and high voltage DC systems, while as high voltage AC overhead power lines are the major source of AC interference. Additionally, the presentation looks at AC interference from the dual perspectives of safety and corrosion-risk. Finally, the presentation suggests practical methods of minimizing interference for improving the integrity of pipelines.

Abstract

Name:  David Flanery
Title / Position:  Business Development Manager
Company:  Deepwater Australasia Pty Ltd

David Flanery is the Business Development Manager of Deepwater Australasia, an offshore corrosion control company, specializing in cathodic protection and corrosion engineering.  David has worked in multiple positions at Deepwater for over 13 years, including offshore inspection, subsea installation, corrosion design and project management.
 
David earned a B.Sc. in Microbiology from Texas A&M University in 2001. He is a longtime member and certified CP Technologist by the National Association of Corrosion Engineers (NACE).  Additionally, he is a committee member with Subsea Energy Australia.
 
David hopes to improve industry awareness of corrosion prevention through design and field feedback.
Three recent project case histories will be presented all of which have used innovative firsts to provide a cost effective asset integrity management solution. Firstly we will present the largest impressed current retrofit system ever to have been installed on a single offshore asset. This project engaged three firsts; a new high capacity subsea anode system, a wireless (subsea bluetooth) linked monitoring system and a modular topside switch mode power supply system rated at 8000 Amps. Second will present a diverless retrofit solution for an FPSO that comprised of an innovative anode system along with new concepts of operation, verification and control. Thirdly we will review at a newly developed IRM based short life extension concept for ageing platform structures in up to 75 meters of seawater. The innovative approach uses sacrificial anodes in a new way to reduce the costs of brownfield maintenance by integrating seamlessly into IRM programs.

Name: Minxu Lu
Title / Position:  Professor
Company:  University of Science and Technology Beijing

​​Minxu Lu, Professor, Ph.D, born on May 28, 1954, obtained bachelor and master degree from Beijing Institute of Aeronautics and Astronautics respectively in 1982 and 1985, and Ph.D degree from Northwestern Polytechnical University in 1992. Currently, he is a chief professor of University of Science and Technology Beijing, and the vice-director of the Corrosion and Protection Center of the University and is the director of Oil and Gas Corrosion Control laboratory. Prof. Lu’s research direction involve CO2 and H2S internal corrosion, corrosion resistant alloy development, cathodic protection and AC/DC interference, pipeline integrity etc. He has published or co-published over 200 papers, 8 books and over 40 patents. Prof. Lu was the vice-chair of NACE EAPA (2014-2015) and the Chairman of NACE Shanghai China Section (2014-2015). He was given the NACE Technical Achievement Award in year 2016.
In order to alleviate the urban traffic pressure, subway systems have been constructed in great scale in many big cities of China. More and more gas or oil pipelines buried within or near city area have suffered from dynamic DC interference caused by subway system. The effective measurement and protection technology for dynamic DC interference have been explored in several cities of China. Firstly, the characteristics of dynamic DC interference caused by subway will be introduced. And then the measurement technology for pipe to soil potential under dynamic DC interference is studied by both laboratory and field experiments. In addition, the combination measurement method including both buried pipeline and rail is carried out. Based on the measured data, the distribution of potential and current along buried pipeline suffered from dynamic DC interference is analyzed. Besides, the design method of the protection system for dynamic DC interference is explored through field test and calculation. In the end, a new set of impressed current drainage equipment was developed and good effect was obtained in field application.
