15 NW branch held a successful event at the University of Manchester on 29 November. The event heard about the fantastic ICorr Young Engineers programme from Danny Burkle and Saif Ramy. Paul Lambert also spoke about Professional Development before the audience also heard from Vincenzo Bongiorno about cutting-edge research into electrochemical noise machine learning. Special thanks to the NW Branch committee, Kathleen Brook at the University, and Izabella Gajewska at Intertek for their hard work in pulling the event together. The branch plans further collaborations with the University in 2024.
15 hardy souls attended an evening city centre tour of Newcastle on 30th November. The party met at the 3 Quarters Bar, The Common Rooms, near the historic Newcastle Central Station and was duly fortified, led by a wonderfully informative and entertaining guide around many of the sights, old and not so old. The first stop was the Bigg Market (it was a sheep market many years ago), followed by the Mediaeval West Wall from the 13th and 14th centuries, looking up at the huge edifice of the home of Newcastle United, St. James’ Park. It was then on to Old Eldon Square, the Monument (to Lord Grey of Earl Grey tea fame), and a walk down Grey Street, with its wonderful Georgian architecture. After a short refreshment stop at the Old George pub, another historic location in the Cloth Market, the walk continued down to the quayside via St. Nicholas Cathedral, the Newcastle Mediaeval Keep, and stopped on the quayside opposite The Glasshouse (formerly The Sage), music venue with great views up and down the river to the many bridges across the River Tyne, including the Swing Bridge, the newer Millenium Bridge and the Tyne Bridge itself. The tour finished at the Redhouse Pub with some food and refreshments. The feedback was excellent, new contacts were made and we thank our sponsors for the evening, Jotun, Safinah and CIM.
The branch held its 34th annual Christmas luncheon at the beginning of December at the Royal Overseas League in St. James’s. 150 guests enjoyed a four-course Christmas-themed lunch before being entertained by an after-dinner speaker. The event was hosted by George Winning, the new branch chair, who took over from Polina Zabelina in November.
Before Sitting Down to Eat, there Were Pre-Lunch Refreshments, and Time for the Guests to Meet Each Other.
The After Dinner Speaker, Ian Irving.
The After Dinner speaker was Ian Irving, a popular entertainer, who gave an amusing sport-themed talk which was appreciated by the guests.
On the 18th January, (moved from the scheduled date due to transport strikes in London), Michael Harrison, Global Product Director-Linings, Sherwin-Williams, gave a presentation on “The Examination of Lining Performance in Renewable and Biofuels and Feedstocks”, sub-titled “why storing feedstocks for biofuel production presents distinct challenges for the specification of tank linings”, at the usual venue, the Lancaster Hall hotel, Craven Terrace, Bayswater.
Michael has 35 years of experience in the protective coatings industry, responsible for the development and testing of heavy-duty solvent-free linings, with subsequent roles in business support and business development. He has also been the project lead in the revision of ISO 16961 (Petroleum, petrochemical, and natural gas industries—internal coating and lining of steel storage tanks).
According to the International Energy Agency (IEA), biofuel use is growing at around 6% a year, and annual production to meet net zero emissions would need to reach over 10 EJ by 2030, requiring an average growth of around 11% per year. Biofuels have an important role to play in decarbonising transport by providing a low-carbon solution for existing technologies, such as light-duty vehicles in the near term and heavy-duty trucks, ships, and aircraft over the longer term. Indeed, according to the IEA, biofuel demand in 2022 reached a record high of 4.3
EJ (170,000 million litres), surpassing levels last seen in 2019 before the COVID-19 pandemic.
However, storing the lipid feedstocks necessary for the production of biodiesel, renewable diesels, and sustainable aviation fuels presents significant challenges for refiners. To avoid the degradation of tank linings and the subsequent corrosion of storage tanks and contamination of feedstocks, it is essential that proper consideration is given to the particular requirements of storing these materials, including the type of feedstock being stored, operating temperature, and storage duration. Failing to do so risks material contamination, tank corrosion, and even production delays. Increasing biofuel production presents one significant challenge for refiners; however, the lipid feedstocks required for biofuel refining have very different chemistries from fossil-based feedstocks, and it cannot be assumed that storage conditions—and the lining systems of storage tanks, in particular—are the same. To understand the issues faced by biofuel producers, a series of tests were conducted that revealed significant degradation of tank linings over time and at certain temperatures, raising important questions for refiners about how they store the feedstocks necessary for biofuel production and the temperatures to which they are exposed.
A two-stage test was carried out under NACE TM-0174 Procedure B, with test temperatures of 71°C, 82°C, and 93°C (based on project specifications), with evaluation at three monthly intervals extending to a minimum of 24 months. The tank lining systems evaluated included proven systems used in typical fossil fuel-derived feedstock storage applications: solvent-free epoxy phenolic, solvent-free epoxy novolac, and novolac vinyl ester glass flake. Feedstock media tested included a combination of waste cooking oil, waste cooking oil +1% water, beef tallow, and beef tallow + 1% water, as it has been reported that the presence of water accelerates the formation of free fatty acids, especially at higher temperatures.
Under phase one of the tests, the impact of higher temperatures on the test samples was apparent at relatively short exposure times. The effects of higher temperatures on solvent-free epoxy phenolic (which is rated at 135°C in crude oil) were apparent at 71°C. The effects of higher temperatures on solvent-free epoxy novolac (rated to 149°C in crude oil) were apparent at ~82°C. Both lining systems failed at 93°C. Broadly speaking, subjecting lipid feedstocks to temperatures above 60°C results in the production of Free Fatty Acids (FFAs) in lipid feedstocks, and the tests again revealed lower limits for these same two linings, with resistance up to 71°C and degradation above this temperature.
A second stage of testing involved two further elements the examination of the oil composition and how it changes at different temperatures, and the expansion of feedstocks to simulate the conditions in the earlier (water cooking oil) tests. Analysis of the oil composition revealed that, up to 60°C, vegetable oils remain reasonably stable with minimal degradation to FFAs after six months of exposure. FFAs are thought to be the aggressive component behind degradation, and this degradation accelerated at 71°C, where the oil degraded to ~12% FFA content after six months of exposure. At 82°C, the formation of FFAs is considerable (>30%). The degradation also appears to be time-dependent, with the FFA level increasing after only three months at temperatures higher than 71°C. This shows why there is no immediate breakdown and stresses the need for longer-term testing. (The normal recommended duration as per NACE TM-0174 procedure B
is 6 months).
Expanding the feedstocks to simulate the conditions in the earlier (water cooking oil) tests involved the addition of oleic acid alongside an unmodified control. This revealed a correlation with the results seen for waste cooking oil and beef tallow under phase one when laced with an additional 5% FFA, although samples with higher levels of FFAs showed rapid degradation. Analysis of these modified oils by both time and temperature of exposure clearly showed that the presence of additional FFAs accelerated the degradation of the oil. Indeed, FFA formation grew faster under these conditions.
Michael Answering Questions at the End of His Presentation.
Testing on these oils demonstrates that, as anticipated, a novolac vinyl ester system can handle the higher temperatures primarily due to the superior resistance to organic acids (such as the free fatty acids seen in renewable fuels.) However, they present greater complications (flash point, storage stability etc.) during application. The lessons learned from this performance evaluation have provided an array of selection tools for biofuel asset owners and facility managers to select the appropriate lining system for their specific processes and needs.
Michael was thanked for his interesting talk and presented with an ICorr pen in appreciation. Information about future branch presentations can be found on the back cover of this magazine, and on the events page of the Institute website. Currently all talks are being held in person at the Lancaster Hall hotel.
On November 28, 2023, the Aberdeen Branch meeting welcomed Dr. Douglas Mills and Tianyang Lan with an online talk entitled ‘Assessment of anti-corrosive organic coatings and green corrosion inhibitors by electrochemical techniques, particularly electrochemical noise measurement (ENM).
Douglas Mills gained a PhD in anti-corrosive coatings from Cambridge University, and after spells at the BNF Metals Technology Centre and the Nuclear Power Company, he has worked in academia and has continued to conduct and supervise research in the field of electrochemical methods for application to coatings, studying and advancing the electrochemical noise method. He was for fifteen years the Technical Secretary of the Institute of Corrosion and is also involved in standards development.
Recent Developments in Electrochemical Noise Measurement (ENM) Techniques
ENM is a series of techniques that can be used to assess the corrosion protection effectiveness of organic coatings. The advantages of the techniques are that they are non-intrusive and both ‘quick and easy’ to operate. The interpretation of the gathered
data is not complicated. The main purpose of ENM is to obtain a single parameter, the Noise Resistance (Rn) which relates to protective ability.
This is the standard deviation of the potential series / standard deviation of the current series.
To obtain an R value, three electrodes are required: two nominally identical working electrodes (WE1 and WE2) and one reference (Re). The natural fluctuations of voltage (potential noise) are measured between WE and RE. At the same time, the natural fluctuations of current (current noise) are measured between the two WE electrodes.
The EMN data is typically gathered over about 4 minutes at 0.5-second intervals (512 data points). Repeat runs are made.
The criteria developed in 1948 by Bacon, Smith and Rugg defined the following:
• less than 106 Ωcm2 – poor corrosion protection,
• between 106 Ωcm2 and 108 Ωcm2 – intermediate level of corrosion protection,
• more than 108 Ωcm2 – good corrosion protection.
There are a number of different configurations of Electrochemical Noise Measurement techniques as shown in the schematic the Standard Bridge method, the single substrate, and the NOCS termed ‘No Connection to Substrate’.
The experimental work had the following aims:
1. Examination of different arrangements of ENM on a range of coated samples and comparison between them.
2. Checking the reproducibility of results and considering the more practical application of this technique in the field.
3. Investigation of NOCS arrangement of ENM.
Mild steel Q-panels were coated with an appropriate coating in the laboratory by a spreader bar.
The types of coating used in the experiments were mainly polyurethane with some Alkyd and others such as Waterborne Epoxy. To get exposure of the coated plates to the corrosive solution, plastic tubes were attached to the samples and sealed with silicon before filling with 3% Na Cl solution- the area of exposure was ~ 4 cm2. Saturated Calomel electrodes were used to measure the Electrochemical noise. An electrometer (Keithley 610) was used to make DC (Direct Current) measurements to compare Rn values with DC resistance values.
Reproducibility experiments were conducted over a period of 5 days, and they demonstrated that the technique gave stable results after multiple set-ups of the experimental apparatus.
A study was conducted to establish if one area of higher or lower resistance could be detected using the apparatus, i.e., if the Rn value of one area was different than for the other two, are we able to detect the odd one? If so, could we measure its value? A design experiment was set up using all permutations to compare high and low combinations of the coated plate resistances.
Designation of Cell DC Resistance Value (Ω)
A 6,40E+09
B 6,35E+09
C 6,40E+09
Designation of Cell DC Resistance Value (Ω)
X 5,50E+07
Y 1,05E+07
Z 1,30E+07
Six areas were used, three with high resistances A, B, C and 3 with lower resistances X, Y, Z, six combinations altogether.
In conclusion for this work, one single NOCS measurement, made with ACM equipment, when one cell was different from the other two, the research team could, by making multiple measurements, obtain the different value of Rn in the combination when the odd one was connected to WE1.
Using ECN for Green Inhibitor Testing
Tianyang Lan of DC Voltage Gradient Technology and Supply Ltd (DCVG).
Tianyang Lan has obtained both a BSc and MSc in General Engineering at the University of Northampton. During his studies, he conducted some Electrochemical Noise research projects under the supervision of Dr. Mills. He has worked as a researcher at the University of Nottingham, Department of Environmental Engineering, applying electrochemical noise and LPR (Linear Polarisation Resistance) techniques to the testing of green inhibitors. He is now working at the DC Voltage Gradient Technology and Supply Company, which has kindly provided various research equipment for the detection (e.g., ENM) and prevention (using coatings and CP) of pipeline corrosion.
Tianyang demonstrated how the EN Bridge Method can be used to assess a number of chemical inhibitors, both green and standard, for the corrosion of steel in hydrochloric acid.
The solution acts as a conduction ‘Bridge’ in the arrangement. The cell comprises a salt bridge with two working electrodes (5 x 2 cm2 carbon steel) with a Saturated Calomel Electrode as the Reference one. Test specimens were blanked off using a Corrocoat Zip E type coating giving an exposed area of 4.5 x 1.5cm2. Specimen holders were manufactured from an ABS material using 3D printing. The stirring speed was related to the size of the stirrer, (e.g. around 300 RPM for 3 cm stirrer).
The study environments were:
• 1 % Propargyl alcohol (C3 H4 O). in 3 levels of HCl: 0.37 %, 2.6 %,
and 5.5 %.
• 0.25 % Green inhibitor (Broccoli or sugar beet) in 3 % NaCl + CO2 /
2.6 % HCl, including two commercial inhibitors.
Propargyl alcohol (PA) is commonly used as an effective inhibitor in HCl solutions in the oil and gas industry. The green inhibitors were experimental test additions.
The results showed that, in Acid, PA provided significant corrosion protection (i.e. a higher Rn), especially in the highest concentration of 5.5% HCl environment. This result follows conventional theory. In 3% NaCl with CO2 bubbling through, the Rn values were found to be increasing over time, apart from when the Broccoli was added, where it actually increased corrosion compared with the control. The 100 ppm dose did better than 50 ppm for both commercial inhibitors, but surprisingly, Sugar beet showed the highest Rn value and also the biggest increase over time, suggesting potential as a green corrosion inhibitor. Comparison was made between the ENM and LPR methods using measurements on the same samples.
• ENM requires two separate iron specimens as working electrodes and one reference electrode.
• LPR measurement requires one working electrode, one reference electrode, and an additional counter electrode. It imposes an external current (±30mV) of the open circuit potential on the specimen.
In summary, the ENM approach gave comparable results to the more established Linear Polarisation Resistance (LPR) method. Further technical events are upcoming by the Aberdeen Branch, refer to Diary Dates at the rear of the magazine.

A comprehensive series of Talks and Demonstrations followed the Introductions, designed to cover all they key Corrosion Topics.
1. Principles and Costs of Corrosion
Steve Paterson, Ph.D, C.Eng, Arbeadie Consultants provided the opening presentation running through the fundamentals of corrosion and electrochemistry with emphasis on what drives corrosion and the corrosion process of metals. He then outlined the different types of corrosion and common corrosion mechanisms and how these related to the Oil & Gas industry. Internal Corrosion mechanisms discussed were: Acid gas corrosion (CO2/H2S) consisting: CO2 (sweet) corrosion, Preferential weld corrosion, H2S (sour corrosion, Mixed sweet & sour corrosion), Sulphide stress cracking (SSC), Hydrogen induced corrosion (HIC), Hydrogen embrittlement, Chloride pitting/crevice corrosion, Oxygen corrosion, Microbial induced corrosion (MIC) and Sand erosion.
Several methods of corrosion control and management were outlined including:
• Materials selection: The most effective solution that can remove the corrosion threat completely (e.g. CRA/Non-metallic material).
• Water removal by dehydration.
• Chemical treatments (e.g. corrosion inhibitor, biocide or oxygen scavenger) a common mitigation method for internal protection of carbon steels.
• Use of Coatings and linings.
• Anodic/Cathodic protection used to limit and control Corrosion in both internal and external situations.
• Control of process parameters/environment, e.g. by limiting temperature and chloride content can reduce the risk of SCC.
Steve then highlighted the costs and significance of corrosion and demonstrated how implementing corrosion prevention best practices could result in savings of between 15% and 35% with the NACE 2016 study quoting savings of 3.4% of global GDP (Gross Domestic Product), giving immense motivation for corrosion engineers to contribute in achieving such savings and associated improvements in integrity of infrastructure and protection of the environment
2. Materials Selection
Rob Howard, PhD, of Lloyd’s Register discussed materials selection critical to the Oil & Gas processing industry making reference to a process diagram from well to final product, he looked at the common types of corrosion witnessed in the process equipment: A selection of materials for corrosion resistance was reviewed showing how we can move from Martensitic and Austenitic Stainless steels up to Duplex and onto Ni and Titanium alloys to get sufficient resilience, albeit with some heavy cost implications.
Rob Howard graduated with a in Materials Engineering from the University of Cape Town in 1995. and worked as a post-doctoral researcher at the Corrosion and Protection Centre, University of Manchester. He joined Lloyd’s Register in 1998 and at present he is the team leader for the Offshore Materials team in LR, whose main function is to provide technical support to surveyors and clients and to review design specifications for oil and gas and offshore wind projects.
He explained how the choice of equipment materials is influenced by parameters such as corrosivity, flowrates and chloride and hydrogen sulphide levels. However, equally important are the heat treatment condition and mechanical properties required, the corrosion resistance and issues such as weldability and ongoing costs for inspection maintenance and repair of materials selected. Rob referenced a number of international sources which are particularly useful for materials selection and stressed the need to examine Manufacturer capability and quality control of the product:
• Norsok M-001 (edition 5, Sept 2014)
• ISO 21457
• ISO 15156 (NACE MR-0175)
3. Oilfield Microbiology Analysis and Data Trending
Carol Devine, PhD, BSc (Hons) of NICMB has over twenty-five years’ experience in oilfield microbiology. She has a particular interest in microbiologically influenced corrosion (MIC), sulphate-reducing bacteria (SRB), seawater injection systems and molecular microbial ecology in general. NCIMB preserve, store and supply a collection of cultures to industry and universities with the largest collection of industrial, marine and food bacteria in the UK and have approx. 10,000 strains; 300 genera; 2000 species – and still growing.
Oilfield equipment is commonly damaged by the presence and activity of micro-organisms in systems for Production, Seawater Cooling, Water Injection, Cooling/Heating and in handling of Produced Water, Firewater, reinjection (PWRI), Diesel Storage & Ballast Water. The Organisms are either Planktonic from bulk water phases or Sessile biofilms on surfaces.
Carol explained the role of the oilfield microbiologist in generating useful and appropriate data in order to:
• Predict which particular systems, vessels, pipelines, locations are under threat from microbiologically influenced corrosion (MIC)
• Prioritise areas for treatment according to budget and time available
• Apply and monitor appropriate strategies to mitigate against the effects of MIC or biofouling
Techniques for analysis where explained: Triplicate MPN’s, qPCR and Metagenomic Analysis (NGS) to assess the threat of MIC and to quantify, identify and assess the activity which needs to be monitored on a continuous basis to see trends from production changes and implement actions to control and prevent system infestation which affects flow and efficiency in the process.
4. Corrosion Mitigation by Cathodic Protection
Dr. Nigel Owen, B.Sc., D.I.C, Ph.D., MIMMM, MICorr, Aberdeen Foundries has worked in the Aluminium Industry for over 35 years on alloy development and manufacturing processes, spending his later years at Aberdeen Foundries as Sales, Technical and Plant Manager, manufacturing Sacrificial Anodes He now oversees manufacturing, testing and design of all subsea and marine sacrificial anode systems.
Nigel explained how the Galvanic table shows naturally what materials are suitable as bases for sacrificial anodes. Aluminium, Zinc and Magnesium being the primary common bases for development of the alloys. With a sufficiently electronegative potential the base material can be alloyed with other elements to make it more electronegative and efficient as an anode. Aluminium has a high current output per Kg consumed and therefore has become the material of choice for anodes, particularly on large structures.
His presentation covered:
• Alloys for Sacrificial Anodes
• Design of a CP system to protect a structure
• Applications of Anodes
• The selection of the CP system:
• The pro’s and con’s of Sacrificial and Impressed systems and their applications.
The process of designing of a sacrificial anode system was explained from assessment of (cathode) material areas and the effect of coating to the calculation of anode mass and current output for a structure in an immersed environment.
Comparison was made between Sacrificial and impressed current systems in terms of their benefits or advantages in given current demand situations and maintenance requirements. Performance being determined by the conductivity (salinity) and the temperature (water depth/ geographic region) of deployment.
5. Corrosion Mitigation by Coatings
Colin Thomson HND, FM Lead at Bilfinger Salamis, has over 20years experience working in oil and gas fabric maintenance after serving in the Merchant Navy. He has supported various clients FM requirements including, BP, and Conoco Phillips, ExxonMobil and Petrofac. He skilfully explained how Fabric Maintenance prevents corrosion, degradation and wear which could otherwise lead to safety and or operational issues. Coatings acts as a barrier to the environment therefore all locations where coatings are damaged must be maintained to prevent metal loss. Colin also brought everyone up to date with modern FM strategies and also instantaneous barrier methods such as anti-corrosion tapes (ACTs) and Corrosion Inhibiting Waxes.
Various key properties of coatings were highlighted including:
• Anti-Fouling
• Environmental Protection
• Fire Protection
• Process Flow aids.
• Safety
• Thermal protection / insulation
The complete range of surface preparation techniques were evaluated along with all factors affecting coating ‘Life Expectancy’ for example:
• Anchor Pattern (too rough or too smooth)
• Chemical Salts
• Condensation
• Existing Coatings
• Fabrication Defects (weld spatter, sharp edges)
• Mill Scale
• Oil, grease and soil
• Surface Corrosion
6. Corrosion and Chemicals Management
Jennifer Watson HNC, Senior Account Manager/Production Chemist at Champion X is currently based within the BP office supporting Glen Lyon FPSO and has over 20 years experience in Oil & Gas operations offshore and onshore. She enthusiastically described all the key chemical mitigations deployed within the energy sector including:
• Biocides for preventing MIC
• Corrosion inhibitors for internal corrosion
• Drag reduction
• Oxygen and H2S scavengers pH stabilization
Jen also discussed all commonly used monitoring processes and analysis methods for rates, chemical residuals and other dosing checks. Most importantly she emphasised the need for having appropriate Chemical & Corrosion Control Matrices (CCCM) in place. These are the basis for understanding individual threats and how they should be mitigated by applied chemical application or other barriers.
A magnificent Lunch followed with an opportunity for all to network.
One of many Networking Opportunities.
7. Integrity Management and Risk Based Inspection.
Simon Hurst, BSc, MSc has been with CAN since 2008 and is currently the Engineering Director where he is responsible for the ENGTEQ business stream and is the nominated Technical Manager under their UKAS Accreditation for Integrity Management and Pressure Systems Inspection. He commenced his talk by defining Integrity Management – BS ISO 55000:2014 states that it enables an organization to achieve its objectives through the effective and efficient management of its assets. The application of an asset management system provides assurance that those objectives can be achieved consistently and sustainably over time.
Simon went on to define some of the key components of Asset Integrity Management including the following:
• Ageing and Life Extension
• Anomaly Management
• Corrosion Control Matrices
• Failure Investigations
• Integrity Operating Windows
• Risk Based Assessments leading to Risk Based Inspection
He then defined with good detail the nature of risk and the various different methodologies for Risk Based Assessment. In relation to CRA’s Simon usefully highlighted that:
• Although the use of corrosion resistant alloys generally leads to an increase in the time between inspections, the subsequent inspection of those CRAs is normally significantly more problematic than say on Carbon Steel.
• The use of CRAs (v CS) doesn’t normally lead to a significant increase in the periodicity for the first in-service inspection as this is more about identifying fabrication type defects than in-service damage.
In closing he reminded Delegates that it is best practice to create a “Written Scheme of Examination” (WSE) that details the applicable degradation mechanisms, and the precise location and inspection technique that will be used in order to try and either find the mechanism or confirm its absence.
8. Corrosion and Erosion Monitoring
Dean Smith is an experienced Operations Manager in the Corrosion Monitoring industry, having started his career as a Retrievals Technician in 2007 and worked his way up to field services management and eventually operations management. He emphasised that erosion and corrosion pose significant challenges to oil and gas production, impacting safety, efficiency, and profitability and effective monitoring techniques, combined with ongoing innovation and investment, are essential to mitigate these challenges and ensure the sustainability of the industry.
Prior to the practical demonstrations, Dean gave a run-through of the key services of Rysco UK which cover the following:
Design & Supply of Internal Corrosion Monitoring Systems including: High & Low Pressure Access Systems:
Field Services including: High and Low Pressure Monitoring Device Retrieval.
• Hot Tapping
