Microbiologically-Influenced Corrosion (MIC) in Pipelines, Detection and Prevention
The full day course is designed to provide an engineering approach to MIC with a focus on pipelines. It consists of two sessions of 3 hours each (morning and afternoon).
Agenda
- Introduction
Revisiting corrosion basics, definitions, pre-requisite for biological growth, impact of MIC phenomenon, major MIC failures, microbial colonisation and tolerance limits, introduction to monitoring techniques and mitigation strategies, and Q&A.
- Microbiology
Corrosion causing microbes, mode of action, microbiological factors influencing the electrochemical process, operating conditions, biofilm formation and characteristics, best studied sulphur reducers, pit development, case studies, and Q&A.
- Monitoring
Sampling requirements and procedures, value of monitoring, types of samples, health and safety, analytical techniques, sessile colonisation, PCR vs serial dilution techniques, factors affecting detection, case studies, best practice, and Q&A.
- Mitigation
Control methodologies, chemical treatment, nutritional and microbial control, bio competitive exclusion, best prevention strategy, selection process, design specifications, hydrostatic testing and commissioning, and Q&A.
- Materials
Affected materials, sulphide corrosion, metallurgical factors affecting MIC phenomenon, alloying and material selection, cause and effect analysis, avoidance measures, case studies, welding effect, operating conditions, and Q&A.
- Identification & Management
Mis-diagnosis, essential analyses, supporting analytical techniques, corresponding bio-minerals, managing MIC, evidence of microbial involvement, risk-based assessment, case studies, performance improvement steps and cycle, and Q&A.
Holds a PhD in Corrosion Science from the University of Manchester and accumulated over 30 years of international work experience. Started his post PhD graduation career with Capcis Ltd. In 2006 Dr. Rizk joined Saudi Aramco, Research and Development Center, Saudi Arabia and was the company main contact point related to bio-corrosion. He developed the company best practice on MIC and contributed to other internal standards. Dr. Rizk is an ex-Honorary Reader at the University of Manchester and ex-CEO of Halo Sealing Systems Ltd. He developed and is the lead of the Institute of Corrosion (ICorr) MIC training course which is the only known certified bio-corrosion training course.
Dr. Rizk authored over 25 papers and numerous confidential reports for different oil and gas, professional institutions and chemical companies. He led a number of failure investigations, updated company treatment and monitoring procedures and mentored junior scientists and engineers. Dr. Rizk led corporate projects and a number of focus teams and steering group committees and represented the company on a number of international JIPs and a joint venture. He also chaired a number of regional and international organizing/technical committees of conferences and technology forums.
