Steering Committee 2023

Since graduating from Delft University of Technology as a metallurgical engineer in 1986, Mr. Jacko Aerts has been working for DSM, now dsm-firmenich. Materials & Corrosion have always been the red line throughout his career path within dsm-firmenich. He started in the materials & corrosion research department, moved to the maintenance group of the caprolactam plant in Geleen, NL, in 1997 and since 2005 he works in a global competence role for materials & corrosion / Life Time Extension, supporting all dsm-firmenich plants worldwide. LTE is essentially predicting when equipment needs to be replaced, thus providing input for strategic investment programs. Representing a small discipline within dsm-firmenich, Mr. Aerts emphasizes the importance of keeping in touch with peers outside your own company: he is chairing two networking groups in The Netherlands: “Studiekern Corrosie” and (until 2022) “Contact Group Corrosion Dutch Process Industry”.

Joelle Greenwood graduated with a master in modern languages in Toulouse (France) and post graduated in Birmingham Aston University UK. Soon after graduation, in the early eighties, she joined Creusot Loire Steel Company (UK) where she engaged in the field of metallurgy for flat and forged products in various chemistries.

Over several years, she developed her activities in the energy market with focus on the power generation and oil & gas (with par-ticular emphasis on offshore) applications. From the late 80’s on-wards, Joelle developed her experience and expertise in sales and project management to include tubular products in carbon, low alloys, corrosion resistant alloys and titanium with the Vallourec Group. Since 1994, Joelle Greenwood has been working exclusively on Tubular seamless products in CRA materials for Mannesmann Stainless Tubes (formally DMV stainless). Based at MST’s French mill since 2003, she is global Key Accounts Manager for the Oil & Gas market including E&P, Upstream and Downstream applica-tions. She is participating in defining suitable approaches in the manufacturing and selection of such materials. She is active on several international normalization committees as well as contributing to key industry events with a passion for CRA materials and the Energy sector. In 2018, she received the Duplex World Lifetime Achievement Award in recognition of her outstanding contribution to the global materials industry.

John Houben has over 20 years experience in material selection, corrosion prevention, troubleshooting, welding and maintenance of petrochemical plants. From 1997, he is responsible for the materials engineering support, including failure analysis of chemical facilities of ExxonMobil Chemical in Europe, Middle East and Far East. In this period a major effort was implementation of Risk Based Inspection Strategies.

John Houben has a Masters degree in Materials Engineer from Technical University of Delft in The Netherlands and is a certified Level III Inspection Engineer in The Netherlands. He joint Exxon Chemical in 1986 in The Netherlands and is part of ExxonMobil Chemical Core Engineering Materials since 1994.

Mr Jan-Willem Rensman is a Fellow for Metallurgy & Welding at Fluor BV in the Netherlands. He is a certified International Welding Engineer and has a Master of Science degree in Mechanical and Materials Engineering from Twente University in Enschede, the Netherlands. His work consists of selection and specification of materials for industrial chemical facilities and refineries, as well as review of vendor documentation for fabrication, non-destructive examination, and welding. Some special interests of his are fabrication technology, materials performance, and failure mechanisms of structural and pressure vessel materials.

Jan van de Wetering studied Materials Science at Delft University in The Netherlands. Joining AkzoNobel in 1992 (now Nobian), he worked as a corrosion prevention consultant in the materials and corrosion technology group. In his first years, he focused on cooling and boiler water treatment and participated in a Dutch national project of the water treatment and chemical process industry to set up a standardized test for cooling water treatment programs. He has been involved in EC funded research and has development projects on the advancement of new electrochemical monitoring techniques for the CPI. He has also been a member of several user committees of Dutch government-funded material and corrosion research projects.
