The final evening event of 2017 was held on Tuesday the 30th May, with 50 attendees representing a wide range of sponsors and also many visiting guests. The Branch was once again honoured to have the presence of ICorr President Sarah Vasey, who provided a welcome update on HQ Plans and thanked the Branch Committee for all its efforts over a very successful 2016-2017 Session.
A technical paper entitled “A Review of State of the Art in Corrosion under Insulation Testing (CUI)” was presented by Simon Daly, Group Oil & Gas Segment Manager of Hempel A/S, who explained the company’s long involvement with CUI R&D, via its association with the Danish Technical University in Copenhagen.
Billions of dollars are spent worldwide due to CUI issues, and as there are many operating variables, failure risks and repair costs associated with undetected CUI, any attempt to lessons these can only be to the Industry’s advantage.
Frequently the weak areas are field joints with field repairs of piping and coating systems difficult to equal in quality to the factory coating systems that are applied under controlled conditions. Similarly external cladding may not be of consistent quality in terms of weather proofing and sealing abilities.
It is not often realized that coatings hidden under insulation must have multiple and simultaneous performance properties and must be resistant in service to, immersion conditions (saturated insulation), thermal cycling (equipment in intermittent use) and varying levels of surface preparation.
Commonly used test methods were reviewed by Simon, along with the benefits and drawbacks of each system. In addition, suggestions were offered for a pre-qualification system which not only takes into account the CUI test itself but also test methods to qualify some of the considerations shown above, as well as likely inclusions in the new ISO standard 19277 ‘Petroleum, petrochemical and natural gas industries – Qualification testing and acceptance criteria for protective coating systems under insulation’, currently under development for CUI protection.
There were many questions from the very attentive audience on a wide range of topics, including future ISO tests on coatings for CRA’s, blasting methods, maintenance painting, life cycle / life extension considerations and use of TSA coatings.
The well supported evening closed with a handover of the Chair to Dr. Yunnan Gao, this year’s Events Co-ordinator, by the current Chair Stephen Tate.
The Branch has one more event before the new session starts, the Annual Corrosion Awareness Day on 29 August at the usual venue, the Palm Court Hotel, which this year is kindly sponsored by Sherwin-Williams.
This course is aimed at graduate engineers, non-corrosion engineers and others working closely with corrosion, (e.g. integrity engineers, inspection engineers, etc.). The full-day course, will comprise a number of lectures covering different aspects of corrosion, providing basic information on corrosion principles and mechanisms of corrosion control, including,
- Introduction to Corrosion and it’s costs, plus corrosion mechanisms and everyday examples, Professor Paul Lambert (Mott MacDonald)
- Mitigation by coatings and materials selection, and corrosion mitigation by chemicals, Malcolm Morris (Sherwin Williams)
- Corrosion mitigation by cathodic protection (sacrificial and impressed current), Nigel Owen (Aberdeen Foundries)
- Corrosion monitoring and microbiology – analysis and data trending, Dr Carol Devine, North East Corrosion Engineers Ltd
- Corrosion management overview and risk based inspection, Hooman Takhtechian (Oceaneering)
- Corrosion rate modelling, Dr Muhammad Ejaz, Plant Integrity Management Ltd.
The objective of this course is to improve understanding of corrosion processes and to raise awareness of corrosion management. The course is hosted by ICorr Aberdeen through kind assistance of its local / national sponsors. As spaces are strictly limited, they will be allocated on a first-come first-served basis. For registration or further information please contact email@example.com
For information about all forthcoming Aberdeen branch activities, please contact the new session chair, Dr Yunnan Gao, ICorrABZ@gmail.com.

Aberdeen Branch have also established a new Media Centre, which can be found at ICorrABZ@gmail.com
There are some exciting developments in the world of training coming up. The “fundamentals of corrosion” course that fills the gap for people wishing to upgrade to professional membership, but lacking in formal corrosion training, is now in place. In addition ISO 15257 has been published, which means the current BS EN 15257 will become BS EN ISO 15257. It just needs translating from ISO standard languages (English and French) to the European standard languages (English, French and German). This standard extends the reach of the Cathodic Protection (CP) training and certification scheme, and incorporates the existing NACE CP scheme. As a result the certification paperwork and training courses need a little tweaking (the ISO has 5 levels and the BS EN currently only has 3). Levels 1 to 3 in the current CP schemes correspond to levels 2 to 4 in the ISO scheme. PDTC are working on a rapid implementation of the ISO standard to limit the confusion. As soon as this is done it is planned to offer a trade-up option where people with existing CP cards can have a fresh card with the ISO level stated on it. The CP certification means that clients can be sure that people designing testing and installing cathodic protection schemes have the correct paperwork to demonstrate competence in the correct area, not just a generic CP qualification. It also means that those installing CP systems can demonstrate to clients they have the right skills for the job, and justify why they should be included on CP tenders. It also means they have the best chance of not having to repeat work and revisit sites to rectify problems caused by using unskilled, uncertificated people.
The new Senior Cathodic Protection Technician Level 2 Marine Metallic structures Course was run successfully on 8h – 12 May at Poole Museum and RNLI College jetty.
The course, written and presented by David Harvey CEng, FICorr, covered the application of cathodic protection to harbours and jetties, offshore structures, subsea structures and pipelines. Date and venue for the next course is yet to be set.
The National Highway Sector Scheme 19A is pushing to get apprentice schemes set up that are based on the ICATS scheme. This enables companies to draw down on monies that have been taken as a levy, and placed in a government training bank. Once this has been sorted out for the ICATS scheme, the possibility of extending it to cover other training options, will be considered. It’s not a straightforward process, but it’s a goal for ICorr. As part of the apprenticeship schemes ICorr are looking at becoming registered with OfQual, to give our training schemes and qualifications a more widespread status.
If anyone has any training needs, concerns or worries, feel free to email firstname.lastname@example.org, and a member of PTDC will respond to them.
I had the pleasure of attending the North East Branch summer event in Durham recently, it was well attended by members old and new. We had a tour of the Castle followed by an excellent presentation from Professor Jon Gluyas entitled “Energy past, present and future”. It was a thoroughly interesting evening enjoyed by all.
This month has been a busy one, I was invited to join the BCF meeting on behalf of ICORR, where it was great to see so many ICORR members round the table.
We have also launched the re-vamped website this month, which has been a great effort by many behind the scenes, and I do hope that you will see the benefit. One of the big changes is that new members are able to sign up directly on the website, and moving on, this reminds me that you should have all received your renewal letter and I hope you have found time to renew your subscriptions, which from next year is also something that will be available to members, who would prefer to do this online.
As some of you will recall we have now organised two programmes of educational training courses aimed at Young Engineers, which involve a series of lectures and a group case study, the conclusions of which are then presented to an audience of their peers and judged by a panel of industry experts. The winners from the last programme won the prize of attending the NACE conference in Vancouver. We are planning to run this event again, so if you are interested in being a candidate, or would like to nominate a candidate, please let me know.
I would finally like to highlight an upcoming event being held by the Aberdeen Branch, the ICorr Corrosion Awareness Training Day on the 29th August. This is an annual event and always well worth attending.
Sarah Vasey, ICorr President
After a year’s hiatus the North West Branch held a lively Golf Day followed by the AGM. The meeting was well attended and the incoming Chairman is Andy Bradley of Omniflex, a manufacturer of specialist monitoring and control systems including cathodic protection power supplies for reinforced concrete.
At the meeting several options for the forthcoming year were discussed, including the Christmas meal, golf day and AGM, together with an initial couple of technical events. On the 4th of September, Chris Atkins will be outlining the new international standard on cathodic protection training and certification at an evening meeting. This is an important document that extends the remit of the current BS EN 15257 to draw in NACE influenced areas. There are a number of changes that need to be highlighted, along with the Institute of Corrosion’s programme for rolling the new scheme out.
On 4 October the Branch will be supporting Salford University in the one day ‘hackathon’ on Lean Construction. Lean is all about removing waste, be it physical waste, or wasted time, energy and effort in processes (see technical article later in this issue). Salford hope to bring together key people who represent the processes involved in corrosion protection of structures with Highways England. The outcome of the day is aimed at producing a research package, or series of packages, that they can obtain funding for and develop something that is not only academically interesting, but of practical added value to the industry.
The Branch had their summer event at Hatfield College Durham on 6 July, including a very interesting tour of Durham Castle with a wee bit of a history lesson!
Durham castle is the ancient palace of the Prince Bishops of Durham. It was built on the order of William the Conqueror on his return from Scotland in 1072 as a projection of the Norman kings power in the North of England. Strangely enough he thought we were a bit ‘wild’, no change there then! The tour took us around the two chapels, the Norman chapel built in 1078 & Tunstall’s chapel built in 1540 exclusively for the Prince Bishop. The last wish of the Prince Bishop in 1837 was to leave the castle and all surrounding land to form the University, which at the time was heavily challenged by London and the government, but they thankfully lost. To this date it it is still owned as used by Durham University and quite frankly is impressive. It is a fully functional home to students who use the grand ballroom for breakfast and dinner, and the upper floors are now student accommodation for the lucky ones.
The second part of the evening was taken up by a very informative and interesting look at “UK Energy Past, Present and Future” presented by Prof Jon Gluyas, who is currently Dean of Knowledge Exchange and Director of Energy Institute Durham University. The presentation covered the issues of the ENERGY TRILEMA which within the UK is seen as relating to Equity/Sustainability/Security. The origins of the petroleum age were described with three important landmark discoveries, Bibi – Aybat Caspian 1846, Spindletop – Texas 1901, and Masjed e Suleyman – Iran 1908. The use of Mineral Oil really took off in the 1860’s and led to reduction in use of Whale Oil therefore resulting in the reduction of whale Hunting! One of the most frightening statistics was that there have been no large Oil discoveries for over 50 years which has resulted in a decline in global reserves. The audience was taken through the issues of declining oil and gas prices and the resultant increase in consumption which again is putting major stresses on reserves. The increase in USA on Shale Gas is having little effect on the reserves which were steady from the 80’s but the gap is narrowing.
The presentation then turned to the situation in the UK showing the trend in energy production and consumption and again a widening energy gap was described through which we as a nation need to address from within the UK. Recent headlines show what is happening to our energy base, the last three deep coal mines are to close resulting in increased imports of coal for the remaining coal fired power stations, Ferrybridge power station to close, and oil & gas platform decommissioning accelerating in some cases 10 years early.
In the 1980’s the UK was self-sufficient in coal/gas/oil, but today is increasing our import of these. Most of our gas consumption is imported from Norway and Qatar, which is a real issue at the moment and we are talking about increasing imports. Most of Europe’s gas in controlled by Russia! Currently UK has 14 days of gas reserves whereas France & Germany have 100 days.
Finally the UK is cancelling many green energy policies making renewables more expensive as currently gas and oil are low in price. UK is considering following US lead and drawing upon fracking as an energy source as well as increasing reliance on nuclear. In summary these are interesting times in the energy industry and the UK needs to find ways of improving its self-sufficiency. One potential source is Geothermal which is estimated to be around 100 years worth of low carbon heating here in the UK, with potential centres in Cheshire, East Yorkshire and Wessex, to name a few. Utilisation of this technology could cut UK emissions by up to 38%.
The Midland Branch welcomed two new sustaining members, Mapei Ltd based in Halesowen, West Midlands, and Cathodic Protection Engineering based in Wythall, Birmingham.
The last Midland Branch meeting took place on 27 June at Amey’s office in Birmingham. As well as updates on Branch and ICorr news; discussions were held regarding future branch meetings and presentations. Peter McCloskey, of Vector Corrosion Technologies then gave two presentations, “ Cable impregnation techniques for protection of grouted post tensioned tendons” and “Introduction to Termarust corrosion mitigation system for steel structures”.
Both presentations were well received and a detailed Q&A session ensued. The Branch would like to thank Amey, Birmingham, for providing the venue.
