Coatings and Linings
The May meeting of the Young Engineers program was held at the CB&I offices in London. This month the topic was Coatings and Linings which was presented by David Mobbs and was warmly received by the enthusiastic audience. The presentation covered the high priority areas of coating including the requirement to qualify products to standards, the standards and what they mean, the testing methods required to achieve this qualification, some typical specifications and the pitfalls and Engineer can fall into. The new ISO 12944-9 formed the backbone of the discussion as it now covers all aspects of coating specification and system selection.
The discussion also looked at modern day options that could be adopted and how innovative ideas are also qualified in the new ISO standard and the requirements for their use.
The Case Study
Prior to the presentation the case study for the program was presented to the delegates. The case study was presented by Richard Carroll of Shell and he highlighted the importance of working together in the teams to deliver the required information as detailed in the document.
Each team will be giving a presentation to be delivered at the November ICorr London branch meeting, the winning team receiving a sponsored trip to NACE Nashville in 2019.
This year the case study is titled “Offshore Heat Exchanger Corrosion Failure” the delegates will be required to;
- Review the design and operating data and propose a root cause
- Define the failure scenarios
- Describe a testing scope to confirm the root cause
- Perform a corrosion risk assessment
- Identify mitigation options to prolong the service life of the heat exchanger
- Design materials for a replacement heat exchanger
We are extremely grateful to all those members of the Institute that give up their free time to help the cause not least the mentors this year, who are;
The teams will meet their mentors in the coming weeks and get going on the case study, a linked in page and drop box have been set up for the teams to help them with this process.
The delegates enjoyed an excellent meal on a canal boat in Paddington after the presentation, hosted by ICorr. A thoroughly recommended experience that all enjoyed.
The next YEP meeting will be on 20th June at CB&I in Paddington and the topic will be Hydrocarbon Fire Protection
Again, we would like to thank our Hosts CB&I especially Sadegh Parvizi for organising the venue, our sponsors BP and our speakers, organising committee and delegates who are travelling from Leeds and Newcastle to attend the event each month.

YEP News – MAY17 – Coatings and Linings (2)
George Gair of Subsea 7, commenced 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.
George Gair – Global Inspection Manager for Subsea 7 presenting to ICorr ABZ
Very clearly the drive is to produce new and robust methods of harvesting sensor data; subsea hardware suppliers are looking at increased in-suite 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.
Significant Integrity Failure found by Advanced Subsea 7 ROV.
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
Monzar Najami – Principal Inspection Engineer of Oceaneering International
The presenters informed the large audience, that the greatest challenge to developing and implementing an asset integrity program 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 delays in the implementation of these activities impede the Integrity Management Programme (IMP) and increase 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)
- Analyze 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)

Aberdeen Newsletter – April 2018 Meeting
An industrial visit to Element Materials Technology in Aberdeen to attend the 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.
An introduction was delivered by Ian Farquharson- General Manager of Element Aberdeen and Edinburgh branches, who declared that Element is ranked as the 5th biggest materials testing and certification firms 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 including mechanical testing, fracture toughness testing, engineering critical assessments (ECA), metallurgy and materials characterization, failure investigation, chemical analysis, corrosion testing and welding engineering services to multi-sector clients around the world.
Phil Dent of Element started the technical presentation by a definition of sour service condition followed by description of 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 by Phil 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 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 explained by the presenter.
Phil Dent, Element’s Global Corrosion Specialist explains SSC Phenomenon
The corrosion testing laboratory visit was accomplished under supervision of Paul Roberts – Corrosion and Chemistry Manager after a brief introduction of the safety points. 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, 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 such international testing standards and protocols as ASTM, IP MIL and NACE.
