Corrosion Management of Seawater Cooling Systems

François Ropital is a materials engineer from the National Institute of Applied Sciences in Lyon (1980), Doctor of the École Nationale Supérieure des Mines de Saint-Étienne in Chemical Engineering (1984) and HDR from the University of Paris VI in Applied Chemistry and Industrial Process Engineering (2002). He works at IFP Énergies nouvelles on the behavior of materials for energy technologies within the Applied Physico-Chemistry and Mechanics Department. From 2010 to 2015 Francois Ropital was editor-in-chief of the review "Oil and Gas Science and Technology - Revue d'IFP Energies nouvelles". Since 2019, he has been an associate university professor (PAST) at INSA-Lyon, in the Department of Materials Science and Engineering. He is also Chairman of the Working Party "Corrosion in refinery and petrochemistry" the European Federation of Corrosion (EFC). Dr Valerie Bour Beucler is a Senior Industry Technical Consultant, and Associate Professor at the IFP School (ENEP Poly). Valerie holds a master's degree in materials science and engineering, and a doctorate from the University of Nancy on the study of a family of organic steel corrosion inhibitors. Valerie then completed a post-doctorate at the Elf Atochem research centre. Before her teaching post she spent many years in industry, as a corrosion manager at CIRSEE at Lyonnaise des Eaux and then over 26 years as an expert in water treatment (cooling water systems and steam generators) at Nalco. Valerie is currently the Chairman of the CEFRACOR "corrosion inhibitors" working party.Antoine Surbled is a material and corrosion engineer from the Conservatoire National des Arts et Métiers (CNAM) in Paris (1972), DEA in electrochemistry from the university of Paris VI (1972) . His professional experience covers commissioning, operations, projects, engineering, inspection of LNG, Oil refining, Oil and Gas production in several global locations for 25 years, then he jointed Shell Global Solution B.V. as senior material and corrosion specialist. He worked on several major projects and offered technical assistance to oil refining, LNG and chemical companies. Since 2011, he has worked as a consultant for several chemical companies in the domain of corrosion and protection against corrosion. He participates in the commission Corrosion in Energy and Process Industries of The French Corrosion Society (CEFRACOR) and working party WP15 of European Federation of Corrosion (EFC).
