The President Writes …

This month has seen the long awaited ‘buried pipe’, which will allow candidates on the CP Course to carry out testing of instrumentation on a live piece of buried pipe, installed at the IMechE Training facility in Sheffield.     This has been a labour of love and frustration for many over a long period of time, but it is also a symbol of what can be achieved when two organizations with some very determined people put their heads together.  This will bring an enhanced learning experience for people attending CP training in Sheffield.  There has also been much time and effort put in by many in recent months looking at how we can be the best in class at the training we offer.

The other wonderful news this month is that we are now in possession of our new home, 5 Saxon Court Northampton.  My sincerest thanks go to Trevor Osborne for the hard and diligent work that he has put in to make this possible.  It has been the wish of Council for some time to see us in a permanent location and that has now been realised.  There are some changes that need to be made to the property, but we are looking at a move in date of November, and we would welcome a visit from you all.

I was lucky enough this month to have a tour of the Sir David Attenborough polar vessel just prior to the hull being launched, but the weather made it feel like a shipyard in Singapore rather than Birkenhead!

We have held productive PDTC and Council meetings, there is good progress being made in our efforts to provide up to date and interesting new courses, and you should see the results of this in coming months.  Council was as ever a lively debate with good progress being seen by the Membership committee.   I would like to take this opportunity to thank Bob Crundwell for his years of service to the Institute as a Past President and active role in the institute, Bob has decided to stand down from Council and we wish him all the best.

I hope you all continue to enjoy the summer.

A Letter from John P. Broomfield on his Paul McIntyre Award

It is a great pleasure and privilege to receive the Institute of Corrosion, Corrosion Engineering Division Paul McIntyre Award.  Paul was a group leader at the Central Electricity Research Laboratory (CERL) when I joined in 1979.  He was leading a group on fracture mechanics and I worked with him and his team on grain boundary segregation using the techniques I has recently mastered in my DPhil work at Oxford University Materials Department and AERE Harwell.  I also worked on the denting corrosion problem in PWR steam generators, oxide dating as a tool for failure analysis and then on the durability of the reinforced concrete foundations of the supergrid towers.

This led me away from power generation corrosion issues to corrosion of steel in concrete and to Taywood Engineering, the laboratories and consultancy arm of Taylor Woodrow Construction, which was building the prestressed concrete pressure vessels for the Advanced Gas Cooled Reactors.  Taywood diversified into concrete durability which meant that I was fortunate enough to lead the group that designed and installed some of the first impressed current cathodic protection systems on reinforced concrete structures in the UK, Hong Kong and Australia.

Cathodic protection of steel in concrete had been pioneered by the late Dick Stratfull of Caltrans who took the concept of a high silicon iron anode in coke breeze backfill and “flattened it out” to apply to bridge decks.  Using pancake anodes and a coke breeze blended asphalt he created an anode that could be used on trafficked surfaces.  In North America they were not using waterproofing membranes on decks which led to massive potholing problems due to de-icing salt ingress leading for reinforcement corrosion and consequent cracking and spalling of the concrete cover.  Stratfull and others also developed the half-cell or reference electrode technique for measuring the corrosion risk of steel in concrete leading to the development of ASTM C876.

In the UK, Europe and the rest of the world our corrosion problems were different.  As waterproof membranes were applied to bridge decks, the problem was the deicing salt run-off onto substructures.  We were also finding problems with calcium chloride used as a set accelerator on buildings.  Trials were carried out on exposure slabs at Taywood’s Labs for the Transport Research Laboratory and then the first trials were apllied on bridge substructures on the Midland Links Gravelly Hill Interchange.  As these were substructures, conductive organic coatings were used.  Taywood worked with one of the leading technical coatings suppliers, Blundell-Permoglaze, to trial and optimise a suitable coating that has the adhesion, permeability and conductivity to be a suitable anode system for reinforced concrete structures.   Meanwhile we had another trial in a building at Marylebone Station with calcium chloride set accelerator and then the VAT office in Southend where it was applied to the calcium chloride ridden first and second floors.

Anode systems continued to develop, first with the mixed metal oxide titanium mesh and titanium ribbon anodes and then with the probe anodes in grids of drilled holes.  The publication of the NACE Standard RP 0290 swiftly followed by the European standard BS EN 12696 formalised the design, procurement commissioning and operation of impressed current cathodic protection systems for steel in concrete.  One of the most important items was the consensus that the 100mV decay criterion was suitable for steel in concrete.  This mean that the accurate calibration of reference electrodes was not essential and if they drifted with time they could be used as long as they were stable over the polarisation or depolarisation period.  It has been shown that it is impossible to recalibrate a reference electrode embedded in concrete so measuring a shift meant that drift was not important.  An excellent report on the background and theory with a section on its application in concrete is given in NACE Report 35108.

I went to present my early work at a NACE conference in 1987 in San Francisco.  The proceedings of the symposium on corrosion of steel in concrete were published as a book by NACE and has been on sale until recently when all papers became available on line.  On my way back from San Francisco, I stopped in Washington DC to meet the start-up staff of the Strategic Highway Research Program (SHRP), which was spending $150 million on highway research, mostly on durability and $50 million specifically on the assessment and remediation of reinforcement corrosion on highway bridges.  I ended up at Technical Contract Manager for that research and worked with some of the leading researchers and engineers in the USA and Canada working on concrete durability at that time.

On returning from the USA in 1990 I set up my own consultancy and I have worked on corrosion problems in reinforced and prestressed concrete all over the world from the National War Memorial in Wellington to a container port in Zanzibar and design and installation of impressed current cathodic protection during construction on a massive building in the Middle East.  I worked on durability modelling for reinforced concrete with the Building Research Establishment and helped in the development and promotion of resistivity and polarisation resistance meters for reinforced concrete.

I have also been active on National and International Standards bodies which I know was close to Paul McIntyre’s heart.  He and I would see each other occasionally at such meetings as CERL was closed down with the privatisation of the electricity industry.  His death in 2012 was a sad loss to the industry.  I have chaired the committee that revised BS EN 12696 on cathodic protection of steel in concrete and then oversaw its conversion to BS EN ISO 12696.  I also chaired committees that produced the NACE and CEN standards on electrochemical realkalization and chloride extraction of steel in concrete as well as chairing and participating in development of a number of other NACE standards, test methods and reports on corrosion of steel in concrete and early 20th century buildings.

It has been an interesting career so far working with very diverse teams. The projects have ranged from applying cathodic protection to early 20th century steel framed buildings such as Selfridges Department Store on Oxford Street to Spaghetti Junction in Birmingham and a recent fascinating project involving the design, installation and commissioning of a retrofitted galvanic cathodic protection system with a 50 year design life on a dock wall. There have also been interesting tunnel projects in the UK, USA and Canada and basements in the Middle East and the UK.

A letter to ICorr Members from the President of CEOCOR

Brian Wyatt Presiden CEOCOR Welcoming the Delegates

Many of you know that in May 2018 CEOCOR held its Annual Congress in Stratford upon Avon. A significant number of those in ICorr with interests in buried pipelines, their internal and external corrosion mitigation, coatings and cathodic protection attended the Congress. This was the first time in the 62 years since the formation of CEOCOR that the Congress had been held in the UK. Those of you who may wish to know about the history of CEOCOR are encouraged to visit the CEOCOR web site and in ‘Bibliography’ and read the ’50 years of CEOCOR.

ICorr and Correx Ltd were responsible for organising the venue, the Exhibition and the Social programme for both delegates and partners. CEOCOR were responsible for the Technical programme. All the bookings were administered by the ICorr/Correx Ltd Office staff. An organising committee chaired by Steve Barke and comprising Sarah Vasey (President), John Fletcher (Immediate Past President), Ross Fielding (Midlands Branch), Brian Goldie (Editor, Corrosion Management) and Brian Wyatt (ICorr and CEOCOR) were responsible for the planning and operation of the Congress. Linda Wyatt was responsible for the Partners’ Programme and two of her ex work colleagues assisted with the registrations and enquires throughout the Congress. I thank them all for their tireless work over many months. There was a dedicated web site for which thanks go to Debbie Hardwick at SquareOne; our President opened the Congress, John Fletcher and Steve Barke were there all the time working to keep it all running smoothly. Thanks are also due to ICorr Council for their support from when this was just an idea and one that might have cost ICorr a lot of money.

Sarah Vasey ICorr President open CEOCOR Congress

The Technical Programme was managed by the CEOCOR Secretary General Rene’ Gregoor from Belgium and the two Presidents of Commissions within CEOCOR, Markus Büchler from Switzerland and Tom Levy from Luxembourg. Key Note Speakers were organised by ICorr.  Again, sincere thanks are due to all concerned.

 Technical Programme

The meeting was opened by Darren Thomas, Asset Engineering Manager of National Grid, who were also the Platinum Sponsors for the Congress. This was an interesting overview of the UK gas transmission pipeline assets, its management and the future challenges within the energy market of the UK. Darren also committed National Grid to the ICorr Training and Certification Scheme for Cathodic Protection Personnel. During the next 2 days there were a further three Key Note Speakers; Peter Elliott (Corrosion & Materials Consultancy Inc.) with an entertaining general paper on pipeline corrosion, Phillip Clisham (GHD) with a very informative paper on the UK water industry pipeline assets and the financial and political constraints for their management and Roger Francis (RF Materials) with a typically comprehensive paper on materials selection for pumps and the need for corrosion engineering expertise at the start of projects, not in the expensive ‘fix it when wrong’ stage.

There were a further 29 technical papers covering topics including:

  • Pipeline coatings
  • Pipeline cathodic protection criteria
  • Pipeline cathodic protection measurement techniques
  • Innovative pipeline inspection systems
  • Innovative coating assessment systems
  • Corrosion in drinking water systems
  • Issues with casings and isolating joints
  • DC and AC Interaction to pipelines and structures


Darren Thomas, asset Engineering Manager, National Grid  Opening Address                 

My assessment was that the quality of the papers was, as is always the case with CEOCOR, first rate and that the delivery of them was excellent. Attendees were presented with these in hard copy and electronic formats. They are not available to non CEOCOR Members for 12 months (join for this benefit; it is only Euro 150) but next year they will be publicly available on the CEOCOR website.

Before and after the 2 day Technical Paper sessions were the Work Group meetings. These deal with technical issues of interest to the members; most of the European Standards related to cathodic protection of buried pipelines have been developed as pre-standards within these Work Groups. Their completed documents are on the CEOCOR web site. Current work includes CP criteria, reference electrodes, internal corrosion, casings and OFF potential measurements. Members and non members are welcome to participate, there are typically 2 or 3 meetings per year with electronic working between times.

Sponsors and Exhibition

The Platinum Sponsor was National Grid. There were 6 Gold, 8 Silver and 5 Bronze Sponsors who also exhibited, there were 4 Exhibitors and a number of Companies also sponsored other elements. All told there were 23 Exhibitors, a record for CEOCOR. One or two thought that they did not have sufficient space, but CEOCOR has always held small table top exhibitions. My thanks go to all of the Sponsors and Exhibitors, without whose support the Congress would not have been possible. Those that I have spoken to directly have all said that this was a success for them. This was not like one of the larger trade ‘shows’; it was an opportunity to display and talk to some of the most senior technical authorities in buried pipeline corrosion in Europe. 100% of the footfall was high quality.

Exhibitors from Steffell Germany 

Social and General

Although the prime reason for attendance was work we also had a great time. We had a fantastic Gala Dinner with hilarious entertainment from the Shakespeare Birthplace Trust and some attendees who were prepared to enter into the spirit of Shakespeare and corrosion engineers! The BBQ, hog roast and Jazz trio was a fantastic networking opportunity. The Partners enjoyed visits all around Stratford and a private tour of Ragley Hall.

In total we had over 150 participants; again a record for CEOCOR. But we measure success by the quality and not the quantity; it was a great success. Those of you who were unable to come missed something really special; those of you who were unable to persuade your companies to Exhibit now know how wrong they were … but we had no more room!

CEOCOR Attendants

What Next

I hope for more UK individual and corporate members of CEOCOR. The next Congress is in Copenhagen; see I know that the organising team of Lars Nielsen and Thomas Larsen will be striving to do even better than we managed to do; they are a good team and it is a good venue …. But they will have to work very hard to do better than 2018!

Hydrocarbon Fire Protection and Fire Engineering -YEP June Meeting

Hydrocarbon Fire Protection and Fire Engineering

By, Philip Hollyman MSc AIFireE MSFPE

Young Engineer Program June meeting was opened by George Winning  with a brief discussion on the Case Study which was delivered to the delegates last month with an update on the programme and the mentors.

Hydrocarbon Fire Protection is a complex; important topics that a young Engineer needs to focus on;

  • Passive Fire Protection
    • What is fire protection and why is it needed
    • Fire types
    • How PFP coatings are tested
    • Factors affecting the loading
  • Structural Fire Design
    • What is it and how does it provide cost and weight savings
    • Magic numbers and real project examples
  • Further Information
    • What information is available
    • Who are the governing bodies
    • Where do I find information

There was some good interaction from the floor with discussion on how Engineers could approach Fire Protection to meet the current project requirements to save weight and costs.

The evening closed with a networking dinner hosted by the Institute of Corrosion and AkzoNobel.

Our thanks as always goes to those who give up their free time to come and assist with the YEP programme and in particular Philip Hollyman from AkzoNobel.
