The first presentation of the year was a hybrid event, at which Kenneth Wunch, discussed “Microbially Influenced Corrosion in Oil & Gas Systems.”
Kenneth holds the position of Energy Technology Fellow at Lanxess in Houston responsible for business development, technology transfer, and shaping the innovation pipeline and strategy for global oil and gas applications. He has 15 years in the industry including positions at Baker Hughes, BP and Dow, and extensive experience in development and field application of biocides, corrosion inhibitors & sulfide scavengers, and is the global Subject Matter Expert in oilfield microbiology, bioinformatics, reservoir souring, microbially influenced corrosion (MIC) and biofouling.
In his presentation, Ken gave an overview Microbially Influenced Corrosion (MIC) in oil & gas systems focusing on:
• Operations that introduce the threat of MIC
• Consequences of MIC including a case study
• MIC assessment and monitoring
Risk management for MIC relies on the application of robust preventive barriers that typically involve the physical scraping of pipelines via oilfield “pigs”, and the chemical application of biocides and corrosion inhibitors.
These preventive barriers are analogous to the control of dental caries which uses scraping via a toothbrush along with a chemical application of toothpaste to limit the microbial growth. However, the surface active and reactive biocides that are applied in oil and systems are designed to prevent or remediate corrosion in much harsher environments.
Routine monitoring for microbial growth and general corrosion is imperative for MIC risk management. However, when preventive barriers fail, Reactive Root Cause Assessments (RCA) utilise various microbial analytical techniques (ATP, qPCR, metagenomics) to identify the underlying cause, and provide corrective actions. Often, these investigations produce unexpected results. For example, a RCA performed for corrosion issues that were suspected to be MIC-related, were actually caused by oxygen intrusion into the system, with identification of oxygen-tolerant bacteria being the key piece
of evidence.
Kenneth finished his presentation by discussing key performance indicators (KPIs) and MIC management strategies, after which he answered questions from the audience.
The branch chair, Polina, thanked Ken for this very interesting and informative presentation.
Hydrotesting, drilling and completion operations in oil and gas systems introduce microbial contaminants into the topside equipment and reservoirs via numerous pathways. For example, offshore platforms can inject 10 quadrillion (1016) cells into the reservoir each day with a proportion of these able to thrive in the harsh conditions of the reservoir and production equipment.
These introduced microbes will become established and form recalcitrant biofilms that can lead to corrosion, souring (H2S production), plugging and separation issues.
Microbially influenced corrosion (MIC) is the localised interaction between microbes and metals where microbial metabolisms accelerate corrosion processes. These metabolisms influence the corrosion process and change the environment via:
• Uptake and excretion of substances that affect the solid material (chemical change)
• Creation of microenvironments (causing physical/chemical boundaries) influencing the local environment
• Deposition of scale and organic material
• Uptake and change of functional chemical addition (parasitic absorption)
It has been estimated that approximately 13% of oilfield pipeline corrosion failures can be attributed to MIC, costing the industry billions of dollars annually. For example, a 2006 pipeline failure on the North Slope of Alaska was diagnosed as due to MIC and ended up costing the operator close to $2B in fines, lost production, and equipment replacement.Furthermore, market economics of having the operations shut down increased the price of oil in the United Sates by $2 a barrel.

The Aberdeen Branch hosted the Young Engineer Programme (YEP) 2022 final on 24th November ’22, at the Palm Court Hotel, which was attended by over 40 in person, plus around 15 attendees online.
It was more than 18 months ago that the branch first considered hosting this event in Scotland, after 3 very successful events hosted by London Branch. David Mobbs, Trevor Osborne, and Danny Burkle, all very kindly supported the branch in the early days of YEP 2022.
The Young Engineer’s Programme was conceived some 10 years ago by the ICorr London Branch, and has been generously sponsored since then by BP, with the following in mind, perceived skill shortages in the industry, preparing graduates for entry into the industry with an enhanced skillset, and to be the first stage in achieving MICorr / CEng.
The ICorr YEP remains extremely popular with our younger and aspiring corrosion engineers, and this 4th YEP had 24 candidates, selected from over 50 applicants The Institute is very grateful to the Aberdeen committee who worked hard, especially Hooman Takhtechian (2021-2022 session chair) and Steve Paterson (YEP mentor supervisor / Case study organiser), superbly supported on the night and throughout the YEP by, Muhammad Ejaz / Adesiji Anjorin, the current branch chair and vice chair respectively.
This year’s selection criteria were:
• Early stage of their career related to corrosion.
• 2 to 6 years relevant experience.
• 35 and under.
• Relevant academic background.
• Based in Aberdeen, or willing to travel at their own cost.
The YEP committee had great difficulty in selecting those to go forward. The case study teams were based on their experience, academic background, and employer, to ensure not being in the same company as the other team members or the mentor, with the average experience for each team being 4 to 4.5 years.
YEP 2022 Participants
The 2022 case study exercise was complex, and focused on good corrosion management approaches under difficult conditions, requiring careful consideration of:
• A 15 year old offshore platform in sweet service.
• Poor corrosion management to date.
• Possible new owner with another 10 years’ service.
• Possible tie-in of new field with slightly sour fluids.
• Dealing with an intermediary integrity services contractor.
• Difficult and demanding client.
• Subsidiary of international operator.
• Based on an actual platform in the North Sea.
• High level assessment (and ranking) of threats.
• Mitigation measures – corrosion management system.
• Material options for required new pipeline.
•
The management and impact of change in operations (MOC).
• Identifying all other relevant factors in dealing with client.

Following the popular festive quizzes of 2020 and 2021, Young ICorr continued this tradition into the holiday season of 2022. Taking advantage of the online forum, the meeting was widely attended with participants from across the world, and consisted of two parts, a talk entitled “A tour of my career and some of the most rewarding challenges” given by Stephen Tate, recently elected as the new ICorr President, and a quiz with a festive twist prepared by Young ICorr committee members, including Izabela Gajewska, Danny Burkle, Harry Wright, and the new Young ICorr chairman, James McGladdery, who also hosted the evening.
During his introductory talk, ICorr’s new President took the participants through various aspects of his career in energy, from the early days of North Sea operations, to his present experiences with both modern and mature assets, covering 42 years of practical experience in the energy sector. Stephen has worked many different roles, including Technical Author, Snr. Corrosion Engineer, Corrosion Technical Authority, and Engineering Manager. He inspired attendees with accounts of his learning opportunities over his long career, as well as its challenges. He emphasised that his present knowledge is built on a foundation of much practical experience from past events and experiences, but corrosion control has been a constant theme throughout.
Following the talk, teams were allocated to enable participants to meet other Young ICorr members, do some networking, and work together answering questions in the festive quiz, comprising multiple-choice questions as well as corrosion, materials, and electrochemistry rounds. The participants learnt what the Christmas tree in the oil and gas industry is, what corrosion mechanisms would affect Santa’s stainless-steel sleigh on the salt covered icy roads, and that “pigs” are not only to be wrapped in blankets but they are also widely used as inspection tools in the Oil and Gas industry to detect issues in pipelines, including corrosion!
In all this was a very successful event, which was well received by everyone. To become part of the Young ICorr community, or for more information

The Surface Treatment Governing Board (STGB) is one of two sub-committees that provide support and advice to the Professional Development and Training Committee (PDTC). The other sub-committee is the Cathodic Protection Governing Board (CPGB). STGB is specifically responsible for the Surface Treatment Training Courses, which include all the Coating Inspection courses and their content.
The main responsibility of STGB is to oversee the Requirements Documents (REQ-DOCs) for each of the Surface Treatment schemes, and which describe the training schemes for the Coating Inspection courses. There are currently three main REQ-DOCs for Surface Treatment Courses, one for courses that are normally delivered in the classroom and a separate REQ-DOC for the courses that are delivered on-line. The new Passive Fire Protection Coating Inspector Scheme has a separate REQ-DOC, as there are significant differences in this scheme, in that the Level 3 Inspectors are required to satisfy a Peer Review once they have successfully completed the examination stage. Currently, this is unique to the new PFP Coating Inspector scheme, and it also reflects that some of the training can be delivered on-line as well as in the classroom.
These REQ-DOCs contain all the guidance for operating the courses and the associated examinations and certification, and detail the syllabus for the specific courses. For example, the Protective Coating Inspector scheme, previous known as the Painting Inspector scheme, has three levels, Level 1, Level 2, and Level 3. The REQ-DOC describes the eligibility of potential candidates for the different courses and details the topics that are covered by the three levels. The Protective Coating Inspector scheme also includes the specific training required for Insulation Coating Inspectors (Level 2), Pipeline Coating Inspectors (Level 2) and Hot
Dip Galvanising Coating Inspectors (Level 2).
STGB keep the REQ-DOCs under review so that they can be updated and improved on a regular basis. Once a REQ-DOC has been edited and agreed by STGB, it is submitted to PDTC with a recommendation that the updated version of the REQ-DOC be approved
and published.
STGB is also responsible for reviewing any new Surface Treatment courses that are submitted to ICorr through PDTC, who refer such courses to STGB where a reviewer with the relevant experience is identified. The review is used to make a recommendation to PDTC with regard to the content and quality of the new course and, where appropriate, its conformance with an existing REC-DOC.
In addition to the REQ-DOCs, STGB review applications from the course providers for candidates who wish to become Course Tutors for the classroom courses, or Course Assessors for the on-line courses, and make recommendations to PDTC regarding approval or rejection of these applications. These applications mainly come from the overseas agents who market the ICorr courses in their countries or regions. In all cases Tutors and Assessors must hold the relevant ICorr certification to be eligible to be considered for these roles.
STGB is made up of about six ICorr members, who have knowledge and experience of coatings and coating related inspections, and STGB is chaired by a Level 3 Coating Inspector.
STGB is always looking for additional members and if you have an interest in joining STGB please contact Keith Wagner via the ICorr Office.
CPGB is a sub-committee of Professional Development and Training Committee (PDTC). Both CPGB and the Cathodic Protection Scheme Manager (CPSM), report to the PDTC Chairman, and work closely with one another to ensure an effective running and management of the Cathodic Protection courses and exams. These include CP levels 1 to 4. All members of CPGB are CP specialists in at least one of the four sectors of CP. The CP Scheme Manager is also a member of the CP Governing Board, which meets on a regular basis.
CPGB ensures as a minimum:
• Scheme is run in accordance with BS EN ISO 15257 – Cathodic protection. Competence levels and certification of cathodic protection personnel, and BS EN ISO/IEC 17024.
• the documents detailing the scheme, course material and exams, are up to date and fit for purpose.
• Document control to ensure latest versions are available for each course.
• Audit the syllabi, the course content, and the course delivery of CP courses.
• Audit both the technical content and process of the examinations.
The CPSM, additionally, coordinates course bookings, training centre availability and candidates, and ensures that the course work and examination material is delivered at the appropriate time and location, examinations are booked, completed, and marked, and the results are fed back to ensure that candidates then apply for their certification on time.
Nearly 20 CP courses were conducted, and 120 candidates attended these courses, in 2022.
The Scheme Manager also ensures that candidate feedback is regularly received by the CPGB as well as the tutors, as this is key to the success of CP courses.
The current CPGB Chair is Raju Narayan, and CP Scheme Managers, Eva and
Bill Whittaker.
