Another year is almost over, and if you’re like me, you’ll have wondered where the time has gone, with all those things you planned to do, but haven’t managed. I had hoped to get more cutting-edge technical articles in each issue, but didn’t quite manage this. However this issue has a bumper four technical articles, two relating to testing and two about above ground storage tanks.
There is a short piece on measuring dry film thickness of thermal sprayed aluminium coatings and the importance of the measuring method, and a thought-provoking look at specifications and protective coating testing, by experts from AkzoNobel.
The articles on storage tanks cover the use of Finite Element Modelling to more accurately design the cathodic protection system, and how looking at an alternative industry helped solve a corrosion protection problem.
Looking forward to next year, there are exciting developments in our training programmes and our move to new offices, and I look forward to bringing you news of these. I would welcome technical article submissions from members (and their colleagues) on their developments in corrosion protection and control. These can be sent to the editor, firstname.lastname@example.org. A list of the editorial themes planned for next year can be found in the media pack at, www.icorr.org/publications.
All that remains is for me to wish all readers the compliments of the season.

The last presentation of the 17/18 season was a joint meeting with NACE UK, and Francois Lirola of Saipem, gave a very interesting talk entitled, “Fusion Bonded Joint: an innovative technology for cost effective plastic pipe installed in J&S lay”.
In deepwater, corrosion protection of flowlines is becoming a major issue. Conventional corrosion allowance of carbon steel flowlines, or cladding, leads to excessive procurement costs, installation weight, welding and NDT challenges. Francois introduced an interesting alternative to achieve an acceptable corrosion protection – is the use of plastic liners. However, plastic lining has been mostly limited up to now to reel lay. SAIPEM has developed and patented an innovative and cost effective field-joint system, the Fusion Bonded Joint (FBJ), which can maintain the corrosion barrier across girth weld locations along the flowline. It has minimal impact on the offshore laying rate and it is based on field proven technologies and methods that are commonly employed in gas transportation networks. The design and fabrication of the FBJ system were explained, and the results of the extensive qualification that has been carried out, were shown.
This excellent presentation led to a high level of discussion by the audience, and the chairman thanked Francois for the time taken in preparing this talk and for coming to London to deliver it.
The third branch event of 2018 took place on Tuesday the 27th March, with 32 attendees representing major companies including, Aberdeen Foundries, ABR Engineering, Atkins, Axiom NDT, CAN Offshore Ltd, DNV GL, ICR Integrity Ltd, Lloyds Register, Lux Assure Ltd, Maersk Oil (now TEP UK Ltd), Oceaneering, One Subsea, Plant Integrity Management Ltd, PROSERV, Shell UK Ltd, Sonomatic and Wood plc.
The event was an industrial visit to the premises of Element Materials Technology in Aberdeen, to attend a technical presentation of “Sour Service Testing of Carbon Steel Girth Welds” by Phil Dent, Element’s Global Corrosion Specialist, followed by a visit to the new H2S / Sour Service Laboratories.
Phil Dent, Element’s Global Corrosion Specialist explains SSC Phenomenon.
Ian Farquharson, General Manager of Element Aberdeen and Edinburgh branches, introduced Element, and noted that is ranked as the 5th biggest materials testing and certification firm in the world following its recent merger with EXOVA. He also mentioned that Element Aberdeen is a UKAS and ISO/IEC 17025 accredited laboratory which offers one of the most comprehensive ranges of metallurgical materials testing and analysis services in the UK.
Phil Dent started his technical presentation by defining sour service conditions, followed by a description of the various types of sour service cracking mechanisms, and the environmental factors affecting the susceptibility of materials under sour service regimes. The sour service cracking mechanisms which were presented included Sulphide Stress Cracking (SSC), Hydrogen Induced Cracking (HIC), Stress Orientated Hydrogen Induced Cracking (SOHIC), and Soft-Zone Cracking (SZC). The various test methods such as the Four Points Bend test (NACE TM0316), C-Ring test (NACE TM0177, Method C), Full Ring test (BS 8701), and Uniaxial tensile test (NACE TM0177, Method A) were also explained.
The corrosion testing laboratory visit was supervised by Paul Roberts, Corrosion and Chemistry Manager, who explained that the corrosion testing services cover a full range of environmental testing simulations, including pipeline corrosion testing for sour and non-sour applications, hydrogen testing, pitting, full ring tests, as well as SCC tests.
Element Laboratories in Aberdeen also specialise in materials qualification for sour service applications and offer standard HIC, SSC tests and also more specialised Full Ring and SOHIC tests and follow international testing standards and protocols such as those from ASTM, IP MIL and NACE. Paul summarised the procedures for the H2S sour service axial tensile test, high temperature / high pressure, electrochemical tests and strain gauging.

The questions raised by attendees during the technical presentation and laboratory visits were well responded to by the hosts. This event attracted a high interest within the professionals and executives of major oil and gas operators, engineering consultancies, and service companies in Aberdeen, to visit one of the major testing and materials qualifications bodies here in United Kingdom. Overall, it proved to be an excellent event in every respect.
The April evening meeting had 78 attendees, and followed on from a very successful visit to Aberdeen by the Marine Corrosion Forum.
George Gair – Global Inspection Manager for Subsea 7 presenting to ICorr ABZ.
George Gair of Subsea 7, started the evening session with a thought provoking theme ‘Subsea Inspection – The Future’, that considered many aspects of the current cost reduction environment where there is a major focus now on how to reduce costs by incorporating new philosophies / technologies.
Very clearly the drive is to produce new and robust methods of harvesting sensor data, and subsea hardware suppliers are looking at increased in-situ equipment monitoring and intervention methods (the oceanographic community has developed remote seabed environmental monitoring systems). George highlighted many significant indicators that show a definite trend towards smarter systems, a key driver being to learn and incorporate inspection technologies from other industries such as Aerospace, Automotive, Medical and Power Generation, together with more efficient use of gathered data.
Monzar Najami – Principal Inspection Engineer of Oceaneering International.
Monzar Najami and Hooman Takhtechian of Oceaneering International followed on with a similarly stimulating discussion on the theme of, ‘Integrity Management of Brownfield Projects: Challenges and Rewards’, highlighting the many important analysis and data gathering areas of modern RBI – Risk Based Inspection methodologies.
The presenters informed the audience that the greatest challenge to developing and implementing an asset integrity programme during Brownfield development projects, is the fact that project schedule and milestones often take primacy over integrity management processes, and in particular emerging vital integrity related interventions which can lead to conflict and disagreement. Any delay in the implementation of these activities impedes the Integrity Management Programme (IMP) and increases the level of risk to the facilities in the operating stage.
Key stages in an IMP project were highlighted as:
Identify stakeholders early in the project (project team, operations, planners, site personnel)
Define strategies and processes and add activities to the construction plan (integrated project activity approach)
Analyse historical data (collect the available list of failures, anomalies and review root cause analysis)
Material fitness for new process (review threats assessment and existing material suitability)
Baseline inspections: Get in early (define scope and input your inspection requirements in the manufacturer’s ITP)
Brownfield revamp activities: Scrutinize output (repair recommendations were challenged and resulted in major cost saving, and change in material selection)
Tagging and RBA output alignment with the existing CMMS (understand the existing Computerized Maintenance Management System prior to your RBA to avoid major re-work)
Deployment of new and advanced inspection technologies (to achieve major cost savings)
A wide range of questions followed the very comprehensive presentation and all the presenters’ slides are available on, https://sites.google.com/site/icorrabz/resource-center.
