September and October Meeting

September and October Meeting

The opening events of the 2017-2018 session kicked things off to a very good start with an average attendance of 50.

Firstly, September was a joint event with TWI, and there was a very interesting presentation by Susan Jacob of CAN (Offshore) Ltd, entitled “An Investigation into the Wrinkling Phenomenon on Corrosion Resistant Alloy (CRA) Pipelines and Its Impact on Pipeline Integrity”.  This focussed on issues arising with both the laying and subsequent inspection of thin CRA internally clad pipelines.  CRA’s have been increasingly deployed for new and replacement Pipe Lay Projects however they can be problematic and great care must be taken at the installation stage to prevent wrinkling, as Susan highlighted.   This topic will be subject of a more detailed technical paper in Corrosion Management in January/February 2018. This upcoming paper will aim to respond in more detail to the many questions raised by attendees, who clearly enjoyed the evening, including, the definitive evidence as to whether pipe lay procedures adequately did, in this instance, address the potential risk of wrinkling and whether (10 years on) more modern methods of fitting CRA Liners are any more resistant to this CRA wrinkling phenomenon; the evidence as to whether applying internal pressure can eliminate the wrinkling risk and as to whether cleaning tools irreparably damage the CRA Liner, or whether perhaps increased Anti-Scale CI and Reduced Cleaning Frequency is a safer approach? The article will also consider the ability of the Intelligent Pigging (IP) Tool to detect thinning changes in a 3mm thick CRA Liner and / or small perforations or tears of this liner, and whether there is a likelihood of ongoing corrosion in the CRA/carrier annulus in cases where CRA disbondment has occurred.

The October special event focussed on offshore external corrosion and repair solutions, which most importantly brought together specialists from two (normally competing) companies.   Consultants, Ian Taylor and Nabeel Khan of IMG Composites Ltd., and Gareth Urukalo, Senior Technical Engineer of ICR Integrity Ltd, worked together to provide an objective insight into the development and application of two key standards, ISO24817: 2015, and the increasingly used ASME PCC-2 Code. The two presentations were entitled “Established Composite Engineering in 2017” and “Composite Repairs – A long Life-time Repair Solution”.

Composite repair has been extensively used in the last 10 years to extend the operating lives of process systems, particularly but not exclusively, for piping systems, which would otherwise have required costly interventions and loss of production and outages that may ultimately have caused the facilities to cease production altogether!

The talks considered some key questions that once again generated much interest from the gathered audience.   What came across was the increasing industry confidence that these composite repairs can provide fully engineered long-term repair solutions, providing additional structural strength (subject to necessary quality controls, such as a high standard of surface preparation), to provide to Energy operators a guaranteed service life.

The ‘new world’ of composites was wonderfully illustrated with many practical day-to-day examples such as the new A380 Airliner and the “New Bus for London”, that contain a very high percentage of composites. For example, the four key structural composite parts which make up the rear end of the new bus support the weight of the engine, the passengers on the platform, the staircase and the upper deck. Using these composite materials has resulted in the saving of several hundred kilograms from the structural weight of the bus compared to traditional materials, and of course very significant fuel savings.

Aberdeen Corrosion Awareness Day

Aberdeen Corrosion Awareness Day

The branch closed its very successful 2016/2017 session with its annual Corrosion Awareness Day, which was well attended with 62 registrations supported by 6 excellent speakers providing a very successful, though very intense day, with many areas of corrosion introduced. This event was only made possible by the very generous sponsorship of Sherwin Williams together with all the Aberdeen Branch Sponsors.

Professor Paul Lambert (Mott MacDonald) provided a wonderful and gripping introduction to the day’s proceedings, outlining some key areas in the evolution of materials and corrosion control methods, as a background to other more specialised areas covered by the following speakers. Dr Carol Devine (ICR Integrity) followed with an amazing insight into the world of integrity wrecking bugs and how they can be controlled and detected, with some wonderful imagery that makes highly recommended viewing ( Dr Nigel Owen (Aberdeen Foundries) gave us the view from the ‘Front Line’, as a busy foundry manager dealing with numerous metallurgical related casting issues, supplying the complex needs of the Cathodic Protection Industries, covering both Impressed Current and Sacrificial CP requirements and differing technologies.

After a well-earned break and some delicious catering provided by Palm Court, Sarah Vasey, ICorr President opened the afternoon CAD Session with a talk on the work of the Institute and its organisation.  Malcolm Morris (Sherwin Williams) then gave us the 3 excellent insights into the world of corrosion mitigation by coatings, chemicals and materials selection with a strong practical bias and highlighted many relevant standards, recommended practices and legislation, essential to ensuring successful performance.

All this fitted very nicely into the final two talks by key Corrosion Management (CM) Specialists, Hooman Takhtechian (Oceaneering) who skilfully guided us into the concepts of CM, how it is geared to best utilising available resources, providing effective communications systems and the avoidance of risk to personnel, in often High Pressure / High Temperature  operating environments.  Dr Muhammad Ejaz (Plant Integrity Management) then wrapped up proceedings with a fascinating introduction to the world of Corrosion Modelling, its historical development and how it can be applied successfully today, which was coupled with a supporting presentation on Intrusive Corrosion Monitoring.

All in all, it was a very comprehensive training session of immense benefit that achieved its main objective of providing a most informative event at a very reasonable cost.

The Aberdeen Branch has further strengthened its management committee for 2017/2018 session and welcomes the following new members who will undoubtedly bring a wealth of new experiences and ideas to its work.  Amir Attarchi (Senior Corrosion Engineer) at Oceaneering International, Dr Philip Enegela (Corrosion Engineer) at ATKINS Energy Division, Dr Nigel Owen (Manager) of Aberdeen Foundries Ltd, and Bryn Roberts (Managing Director) at ABR Engineering Consultants Ltd.

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)
