The Corrosion Science Symposium is one of the premier events in the Institute of Corrosion’s calendar. This year it’s not going to be quite the same as before, but we think you’ll like what we’ve done to ensure it is an equally engaging and enlightening an event as it has always been. The key to its success, as ever, is those who
attend – you.
The CSS has traditionally been a two-day meeting held in a prestigious location befitting of its status, and last year’s event was held as part of Electrochem 2019, at the University of Strathclyde’s Innovation Centre in Glasgow.
Although it is an informal meeting of the CSD in which corrosion scientists, corrosion engineers and PhD students can gather, hear talks on corrosion, and discuss relevant corrosion issues, it does include certain formalities. Presentations of some of the Institute of Corrosion Awards are made during the CSS, including the presentation of the UR Evans Award – the premier scientific award of ICorr, and the Lionel Shreir Award – for the outstanding student talk given during the CSS.
With a more unpredictable future than at any time in our history, the CSS has been moved from a physical space to cyberspace this year. While the exact format is still being finalised, the date and an outline of the format have been set. As it’s going online, rather than an intense two days of sitting in front of a screen, it is being extending to three or four sessions during the week beginning 14th
September 2020.
The exact format, times, and technology being used will be announced nearer the date. One thing is for certain, though – being online, the CSS will be more accessible this year than it has ever been. Consequently, many more international students are expected to take part, and that could lead to some exciting competition for the Lionel Shreir Award, the winner of which will be selected during CSS, and it is currently planned to present the it online on the final evening.

Welcome to another jam-packed edition of Corrosion Management! I’ve had to content myself with reading the online version of the magazine in recent months as the printed version is delivered to my office at NPL and I’m still not permitted to access the site. The online version is fantastic but I have to say I do miss having a printed copy to leaf through. There has been debate for many years within Council about whether the magazine should transition to electronic format – at the moment the consensus is that most members still prefer to receive the printed version. However, this may change in the future, particularly as the demographic of the Institute continues to shift, and we are continuously reviewing the options. It may be that we decide to distribute the magazine by email to those who wish to receive it in electronic format, while keeping the printed version for those who prefer this option. If you have any views or suggestions on this please do not hesitate to contact our Editor, Brian Goldie.
As the world cautiously emerges from the Covid-19 lockdown, I’m pleased to say that our operations are returning to something like normal. Our Head Office at Corrosion House in Northampton has been open for several weeks now, with appropriate social distancing, protective equipment and sanitisation arrangements in place. I would like to thank Denise Aldous for her sterling work in coordinating working arrangements in the office during the lockdown to ensure that any disruption in our service to members was minimised.
This gives me great confidence that we will be able to transition smoothly back to lockdown again in the event of a second wave of the virus. Our classroom-based training courses have also restarted, both at our main training provider IMechE AR in Sheffield and at our international training facilities. Like many organisations and businesses, we expect to see a dip in revenue in 2020 but I’m encouraged by the fact that the preliminary accounts for the financial year to the end of June suggest that our finances are still holding up well, despite the recent significant investment in the upgrade of our training course offering. This bodes well for the longer term and I and the other Trustees are cautiously optimistic that we can ride out any temporary downturn arising from the Covid-19 pandemic.
One thing you can do to help is to renew your annual membership! These are difficult times but we rely on your subscriptions to deliver the services, activities and events that you expect and deserve as members of a professional society. I greatly value the sense of community and professional pride that membership of ICorr entails and I know that this is reflected across the entire breadth of our membership.
Meanwhile, the success of our online events continues apace, with the Aberdeen Branch holding its second Week of Webinars in conjunction with the Marine Corrosion Forum, and delegates on the Young Engineer Programme attending informative lectures on Cathodic Protection (by Trevor Osborne) and Fire Protection (by Simon Thurlbeck). I would also like to draw your attention to two major conferences coming up in September that will be held online for the first time, the Corrosion Science Symposium (Sept 14-17) and EuroCorr (Sept 7-11). Registration for the CSS is free and I would encourage you to attend as this will be a unique opportunity to catch up on the latest cutting-edge research in corrosion presented by informed and enthusiastic PhD students (see news item later in this magazine – editor).
Two prestigious awards will be presented at these conferences. The first is the U.R. Evans Award, the premier scientific award of the Institute of Corrosion, which will be presented at the CSS to Prof. Robert Cottis of the University of Manchester. The second is the European Corrosion Medal, the major scientific award of the European Federation of Corrosion, which will be presented at EuroCorr to Prof. Stuart Lyon of the University of Manchester. This represents a very impressive double for the university and I would like to take this opportunity to congratulate Bob and Stuart for these significant achievements.
Corrosion Engineering Division, Latest News
Working Day, Wednesday 29 April 2020
This one-day meeting was the latest in a series of working days held by the Corrosion Engineering Division. This year’s meeting had the theme of ‘Corrosion Control in Transport and Infrastructure’. Originally, it was planned that the meeting would be held at the fascinating conference venue at the National Railway Museum, York. However, due to the coronavirus lockdown, it was no longer possible to go ahead with a physical meeting and so the division held the meeting on-line using the Zoom platform (set up by the Institute), for the first ever on-line Institute of Corrosion symposium. The meeting was joined by ~60 corrosion engineers from around the world who had pre-registered for the meeting, including from India and New Zealand, despite the time zone differences. Nick Smart (Jacobs) chaired the meeting, which followed the published agenda and timetable. After the technical talks, the meeting divided into individual CED working groups, using the Zoom breakout room facility.
The first talk was given by Phillip Watkinson (Corrocoat) who presented ‘Fascinating Uses of Heavy Duty Glassflake Coatings in Transport Applications’. Phillip described the technical background to glass flake coatings and how they have developed over the years, initially from crude trowel- or brush-applied coatings, using predominantly polyester resins, through to spray-applied coatings using epoxy formulations, that can now be easily sprayed internally on pipes with diameters ranging from 50 mm to over 1 metre. Modern coatings can also be applied using an aerosol method. The methods for producing glass flake have evolved so that now it is possible to have close control over the thickness of the flake used (±1 µm) and to minimise the curvature in the glass flakes. Phillip highlighted the many desirable properties of glass flake coatings and illustrated their application in various industries, including their use on train axles, train air brakes, dip tanks for applying coatings to car bodies and a propeller shaft.
Chris Atkins (Mott MacDonald), presented the second talk entitled ‘Innovations in Preserving Transport Infrastructure’. This presentation focused on the ‘embodied energy’ concept of building materials, which can be applied when considering the amount of energy that is consumed in producing a range of building materials. It is important to take account of this factor in relation to achieving Net Zero carbon emissions by mid-century. By applying the ISO definitions of environmental conditions (ISO 9223) and the decrease in corrosion rate with time (ISO 9224), the approach taken is to evaluate the energy lost in allowing corrosion to take place for steel or galvanised steel, with coatings reapplied every 15 years over the life of a structure. By analysing the predicted energy consumption involved, it is possible to determine the relative energy efficiencies of various coating strategies, such as galvanising, depending on the corrosivity of the environment, the energy consumed in producing the initial material, and the availability of recycling facilities.
Steve Paterson (Arbeadie Consultants, 2019 Paul McIntyre award winner) presented the third talk on ‘Managing Corrosion in Ageing Offshore Infrastructures’. This talk summarised the background to the operation of existing North Sea offshore facilities beyond their original design life, with some structures predicted to be operating for 45 years or more. This can be compared with the operation of the Forth Rail bridge which was originally opened in 1890 and it still going strong because of ongoing maintenance regimes. The various considerations for extending the lifetimes of offshore installations were reviewed and the current guidance available from the Energy Institute was highlighted. Steve summarised the various ageing mechanisms that need to be considered in assessing future lifetimes and the following mechanisms were recognised as key current primary threats to facilities/pipelines: fabric degradation – external corrosion, corrosion under insulation, microbial corrosion, sand erosion and preferential weld corrosion. These corrosion issues were illustrated with a number of examples taken from field operations, followed by a discussion of future challenges, not least of which is the possible closure of facilities due to the current Covid-19 pandemic and the retention of the necessary technical skills within the workforce.
Turning from the oil and gas industry to the nuclear industry, Cliff Harris and Clive Harrison (both Jacobs) presented a talk entitled ‘Corrosion Monitoring of Dry Fuel Storage Containers in Nuclear Facilities’, which focused on the corrosion aspects of dry storage of spent nuclear fuel removed from the Pressurised Water Reactor (PWR) at Sizewell. Spent nuclear fuel is moved from initial wet storage in ponds at the power station and placed into purpose-built dry storage facilities, because there is currently no geological disposal facility (GDF) available within the UK. The fuel is placed into a stainless steel multi-purpose canister (MPC), which is filled with inert gas, welded shut and then placed into a steel and concrete overpack. This system provides passive cooling through the use of convective air flow induced by the high operating temperature of the MPC, and has a planned storage life of up to 100 years. Corrosion studies have focussed on the possibility of atmospherically induced stress corrosion cracking due to the deposition of deliquescent sea salt particles. A corrosion evaluation test programme has involved the use of environmental monitoring combined with the construction of a full-size, fully monitored, MPC corrosion simulator, backed up by laboratory test programmes of SCC susceptibility under a range of test conditions and a study of the deliquescence properties of various deposited salt analogues.
Before the lunch break, Gareth Hinds (ICorr president) gave a ‘virtual’ presentation of the 2020 Paul McIntyre Award to Professor Carmen Andrade, who was located in Madrid, Spain (see report below), highlighting her many achievements in the field of applied corrosion science and corrosion engineering. Following the presentation, Professor Andrade gave a brief illustrated summary of her activities during her career and expressed how honoured she felt to receive the award.
The final talk of the day was given by Pablo Merino (CLH Pipeline Systems) entitled ‘A New CP Approach on Non-Isolated and Aged Pipelines: A Case Study’. The talk was concerned with the corrosion protection of the very large pipeline systems, extending for 10s of km, that support the UK infrastructure, for example for distributing aviation fuel. The presentation covered a review of the various options for manging an oversaturated CP system, which used an impressed current cathodic protection system. Inspections had shown that the pipeline was not achieving the require BS EN 12954 criteria, and that the coating was deficient in a number of areas. The remediation options considered included electrical isolation, coating rehabilitation, upgrading the CP system, and changing the CP criteria to a less restrictive one. The last of these was the only feasible one, backed up by the use of an external corrosion monitoring system, based on an electrical resistance corrosion rate measurement technique.
The final talk was followed by a set of parallel working group meetings for all the CED working groups, namely nuclear, coatings, oil and gas, cathodic protection and corrosion in concrete. At the end of the afternoon, Nick Smart thanked all the participants and contributors, and so ended the first on-line CED meeting. He looked forward to holding the next CED working day meeting at the National Railway Museum next Spring, pandemic permitting! Copies of the presentations will be put in the members area of the ICorr web site, together, where possible, with recordings of the presentations that were given.
