Dr Paul McIntyre graduated from the University of Newcastle upon Tyne with a 1st class honours degree. He spent his early career in the steel industry. In 1978 he moved to the Central Electricity Research Laboratories in Leatherhead as group leader of EAC studying stress corrosion, localised corrosion and corrosion fatigue in conventional and nuclear power plants. Later he was involved in asset management and remaining life assessment of components including development of remedial methodologies such as RAM (reliability, availability and maintainability) and RCM (reliability centred maintenance). From 1996 until 2006 he was Editor or the British Corrosion Journal (which became CEST). For six years from about 2004 until 2010 he worked as consultant in the electrochemistry and corrosion group at NPL. His scientific insight and depth of engineering experience was critical to successful analysis of a wide range of failure investigations including fracture of wind turbine bolts, corrosion pitting in a desalination plant as well as providing informed corrosion control guidance to industry. Paul wrote almost 60 published papers and over 200 internal reports. In addition to his career in industry Paul had almost thirty years of participation in corrosion standardisation within BSI and ISO committees. These included being past chair of ISO/NFE 8 Corrosion of metals and alloys, and UK representative on the equivalent ISO committee TC 156 and within that being secretary of WG2 Stress Corrosion Cracking and member of WG 7 Accelerated Corrosion Tests. He made an immense contribution as Scientific Secretary of the EFC. He was also on the Council of the Institute of Corrosion from the early 2000s specializing in standards work and pan European activities. In 2003 Paul was awarded the T B Marsden prize of IOM3 for his considerable achievements in promoting standards, education and publishing in corrosion and materials. The chair of ISO TC 156 stated at the award citation “Paul has provided more input into the development of ISO standards in the corrosion field than any other individual”. Paul was invariably polite and accommodating to everybody. But he had core of steel and dry sense of humour. In 2010 he was diagnosed with secondary liver cancer and very sadly passed away in 2012
The branch kicked off 2018 with 3 well attended events with an average attendance of over 60 people, beginning with a special cathodic protection evening on the 30th of January. In the first of two presentations, Edgar Rodrigues of TAQA gave an excellent talk on “Impressed Current Cathodic Protection Retrofit Strategy in the North Sea”.
TAQA’s fixed drilling and production installation was installed in the North Sea in 1980 in 161 metres water depth approximately 110 miles north-east of Lerwick in the Shetlands. The platform jacket has 8 legs and was installed with traditional stand-off galvanic anodes, but its sacrificial CP System is now beyond its original design life. Surveys from 2010 to 2013 indicated a reduction in corrosion protection from the CP system, and plans were implemented to upgrade this. A remote impressed current CP (ICCP) anode sled system was selected, installed and commissioned in early 2016. This presentation discussed the CP design process and the many challenges in choosing what was at the time, the largest ever CP retrofit, both in terms of delivered current capacity offshore, and the CP current demand of the structure required to maintain external corrosion protection.All retrofit CP systems however require regular CP data to validate CP performance and this can often be erratic and costly to obtain, typically involving ROVs, as was discussed in the second presentation of the evening.
Andy Smerdon of Aquatec Group continued the evening with a very interesting and complimentary presentation on “Retrofit CP Monitoring to Reduce Inspection Frequency”. Aquatec was founded by the current managing director in 1990 as a specialist consultancy in oceanographic instrumentation design.This presentation described a CP toolbox within a UK North Sea case study, comprising monitoring and communications modules that were used to provide high quality CP potential and CP current data sets, accessed remotely from diving vessels and platforms.The cost of CP monitoring equipment when simultaneously installed with retrofit CP systems, is relatively low and normally recovered by dispensing with just one conventional subsea inspection campaign, in favour of remotely retrieved data.
The branch’s second event in January, took place at the School of Mechanical Engineering at Aberdeen University, where a Corrosion Awareness training session was held. In the packed two hour event, there were 6 presentations covering corrosion theory and failure mechanisms, principles of corrosion management, materials and coatings selection, risk based inspection, cathodic protection, chemical and corrosion monitoring, all of which prompted a number of interesting questions from the enthusiastic audience.
Retrofit CP Monitoring
In recent years, ICorr Aberdeen has established a strong working relationship with the Aberdeen branch of IMECHE and in particularly its Young Engineer Panel, and a further more extensive Corrosion Awareness event will follow in August 2018, details will be announced in the May/June magazine, and on the branch website.
The February event focused on internal corrosion management Issues, particularly corrosion mitigation by chemical control and optimisation. A very enjoyable and informative presentation was given by Emma Perfect, CEO of LUX Assure Ltd, who described the development of an onsite technique for measuring dosage of corrosion inhibitors used in the protection of pipelines. This advanced technique was developed as there was a perceived need to identify more quickly, and more accurately, when dosing levels of inhibitor were either below or above the threshold for protection, and hence allow an operator to adjust levels to better protect equipment from corrosion, or have options to lower the dosage level to reduce costs of inhibitor supply.
Development of the LUX Assure Control Concept commenced in 2008 and the company has been supported by key energy industry players including Chevron, ConocoPhillips and Statoil Technology Ventures, along with the Scottish Investment Bank and Archangels / Private Investors. The technique relies on the fact that corrosion inhibitors form micelles in the body of the fluid once all available sites for absorption are occupied. This is essentially a saturation point, and the micelles formed increase in concentration as inhibitor is supplied in excess of optimal levels.
With access provided to suitable trial sites, the development of the technique and a suitable kit for onsite monitoring progressed over a period of 3-4 years until it was fully commercialized in 2013.LUX Assure gathered data to show operators that this technique could be used to test fluids and identify the Critical Micelle Concentration (CMC) of a surfactant above which micelle formation occurs. But the real challenge for LUX Assure was to develop a kit, (now known as CoMicTM) which operators offshore could use to sample and analyse fluids in the field in relatively uncontrolled environments without precise preparation. The specialised kit includes detection reagents and an optical analyser. Final data processing evaluation of the sample is still currently performed back at the offsite laboratory and results and advice swiftly communicated back to the field, but a full onsite service is currently being progressed.
CoMic Testing Kit
The presentation, which was well received, went on to describe case studies and discuss when samples may not be suitable for testing, and also the correct use and interpretation of the data for the test situation. It is hoped that in the near future that all data interpretation can be made by the test operator if a practical and proven site assurance system can be developed.

The February talk was on the use of Electrochemical Impedance Spectroscopy (EIS) as a predictive tool for coating lifetime, and was given by Dustin Traylor, Global Product Manager of Axalta Coatings Systems. This was an excellent presentation which produced significant discussion amongst those attending. The concept was to raise awareness of new predictive modelling techniques for coating life and performance.A new generation of high temperature coatings, in particular high glass transition temperature Fusion Bonded Epoxy (with aTg of 205 C), are being developed as a lower cost alternative to expensive alloy steels.However, the highly-functional epoxy resin and ingredients in these new coatings can make interpretation of testing results difficult for coating specifiers. Dustin explored the benefits of using EIS after atmospheric testing to assess a coating’s life expectancy. The conclusion was that EIS did have a part to play in conjunction with accelerated weathering, Autoclave and Atlas Cell tests, to assist in the determination of expected coating life.This technique has now been adopted by Aramco and Chevron and is gaining credibility as a useful tool in the pipeline market.
Thebranch AGM was held ahead of the Marchevening technical meeting, at which David Mobbs (Chair) delivered a short presentation on the achievements of the branch over the past year, including confirming that the move to Imperial College had increased attendance from 20-30 to 40-50 per meeting, and that our finances were good.He outlined the steps being taken to obtain speakers to present new technology, new ideas and having more technical content, and noted that the membership affiliated to the branch amounts to 45% of Institute members, and 22 members qualified for 20 or 30 years long service pins.He finished by thanking everyone for their support, and the speakers and committee members who give up their time voluntarily to make it all work.
Mark Stone of Sonomatic Ltd then gave a presentation
on the technology advancements in integrity management
of storage tanks.The industry is well versed with non-intrusive inspection of vessels and pipework, but corrosion mapping of storage tanks has always relied on man entry and physical base plate inspection. However, the industry does not like working in confined spaces and there are moves towards zero-man entry over the lifetime of storage and process vessels. Mark explained that tank inspection plays a major role in effective integrity management of storage tanks, which historically has relied on emptying the tank and personnel entry for cleaning and inspection, and that the common method of using Magnetic Flux Leakage testing is not necessarily the most effective method of determining metal loss.Sonomatic have developed a range of methods for inspection of these tanks while in-service, whichincludes the use of traditional shell wall inspection using crawlers, coupled with a new technology to determine metal loss of the tank shellusing multi skip technology deployed around the outer chine of the tank.
The key element of this testing programme is the use of robotic cleaning and inspection of the floor – the tool is dropped through the tank fluids to the floor and remotely guided by use of sonar. Firstly the level of sludge is determined, and then the tool removes this and scans the base plates, the results of which are transmitted to a mobile unit outside the tank where a statistical analysis is carried out. The presentation included a case study of a field application.
Mark Stone of Sonomatic
This was an excellent presentation and there was a high level of discussion around the floor.The chairman’s opinion was that the real value of this testing procedure was that it was an ‘iterative process’, whereby a tank farm operator could screen all the tanks and identify which were detected as the worst. On opening the tank and carrying out full base plate inspection it would be possible to check the model to see how accurate it was, and by the time the third tank had completed its full inspection, the model would be pretty accurate, and could be used in future with more certainly.
