African Corrosion Journal & Congress

Discussing African Corrosion solutions for African problems

AfriCORR '14 - It Begins...

After months of planing and hard work AfriCORR'14 happened and with the feed back received from the close to 100 delegates it will happen again... 

The inaugural African Corrosion Congress provided a forum for African and International researchers and industrial practitioners in the field of corrosion to explore African corrosion challenges and develop African solutions thereto. It was hosted by the Corrosion Institute of Southern Africa, AfriCORR provided a welcome arena for interested parties to gather together to share, discuss and learn from each other. 

Keynote Speakers were: 

Dr Herman Potgieter

Herman Potgieter holds, amongst others, a Ph.D. degree from the University of the Witwatersrand and has worked in corrosion for many years, and has held positions at Mintek, Tswane University ofTechnology, and the University of the Witwatersrand, South Africa, where he was Head of the School of Chemical and Metallurgical Engineering. He is currently a professor at Manchester Metropolitan University, UK. Herman has supervised more than 35 postgraduate students (masters and doctoral degrees) and has published more than 190 peer reviewed papers and 40 other conference contributions. He is associate editor of the journal Corrosion Engineering, Science and Technology and is an editorial board member of the Journal of Hazardous Materials, Journal of Nuclear and Radiochemistry and international board of the Journal of the South African Institute of Mining and Metallurgy.

Prof. Margaret Stack

Margaret Stack has been Professor of Mechanical Engineering in University of Strathclyde since 2001.  She has published over 160 papers in the fields of wear, erosion and erosion-corrosion.  The focus of her work has been to develop materials maps for tribo-corrosion, which involve processes from oil and gas conversion to bio-implants and tidal energy.  She leads the International Network on Tribo-Corrosion. She is a Fellow of the Institute of Physics and IOMMM.

Dr Chris Ringas

Chris Ringas obtained his Ph.D degree from the University of the Witwatersrand in Johannesburg, South Africa. He is currently the CEO of PPT, a position he has held since PPT was formed in 2000. Prior to that, he was employed for over a 10 years at the CSIR, in a variety of technical and managerial roles. He has 30 years’ experience in the field of asset maintenance, inspection and repair specializing in physical metallurgy, corrosion, microbial corrosion, cathodic protection, waveform analysis, DCVG surveys, CIPS surveys, CCTV inspection, pipeline integrity and ECDA. He has undertaken over 175 failure investigations over this time period, been project engineer on large pipeline inspection projects, both locally and internationally. He has carried out projects in the oil and gas sector in various parts of the world including USA, France, Nigeria, Mozambique, Namibia and South Africa amongst other places. He is an editor of Anti Corrosion: Methods and Materials, a UK-based technical journal, published monthly for the international market. Chris has published over 40 technical papers in local and international journals and also a NACE certified CP specialist and a Chairman of the SABS TC 59 Committee.

Mr Neil Webb

Neil Webb’s major field of experience has been in cathodic protection, particularly in close interval surveying, pipeline refurbishment and stray current mitigation. He was part of the design team for the Mossgas FA platform, and commissioned the first application of cathodic protection to reinforced concrete in South Africa. He has developed several innovative CP systems for pipeline networks, composite foundations and intrinsically safe CP systems for LPG bullets. Several of these projects have been recipients of the Corrosion Institute Annual Award. He has been responsible for cathodic protection design for some high profile projects such as Nelson Mandela Bridge, Wlotzkasbaken desalination plant, Ben Schoeman Dock refurbishment amongst other projects. Neil has given lectures locally and internationally with over 70 presentations on cathodic protection, metal sprayed and organic coatings, and plant maintenance. He has been awarded various medals as recognition for his contribution to lecturing and technical training by the Corrosion Institute of Southern Africa. 

Mr Louis Pretorius

Louis Pretorius is the elected member of South Africa to the ICC, International Corrosion Council, as well as the South African Representative to the WCO, World Corrosion Organisation. He is the Past President of CorrISA, Corrosion Institute of South Africa and a past Chairman of SAQCC Corrosion Protection. He has authored numerous technical papers both in South Africa and Internationally. Furthermore, he authored a section in the training textbook of CorrISA entitled " Corrosion Control in Southern Africa". He is a member of NACE and PCISA, Polymerics and Composite Institute of Southern Africa. Louis is currently the Managing Director of Corrocoat SA and extensively involved in technical training and lecturing.
