Branch News - London Branch

The Branch began the New Year by welcoming the “Three Wise Men”, Alan Denny, AKD Materials Consulting, Bill Hedges, BP, Corrosion Engineering Technical Authority and Steve Paterson, Shell (Amsterdam), Principal Technical Expert Upstream Materials, who gave a presentation entitled ‘The Past, Present and Future of Corrosion’ .

Alan Denney illustrated his past experience with numerous and far reaching projects and corrosion problems, including reinforcement corrosion in buildings, graphitic corrosion of cast iron, the use and misuse of Cor-Ten steel, the use of duplex stainless steels in architectural demanding buildings together with a number of issues in the oil and gas industry. Bill Hedges then looked at what the corrosion industry was doing well, such as technical development, networking and training, risk assessments, corrosion modelling, effective corrosion barriers and management systems. He then stated that opportunities for improvement existed in, attracting the next generation of engineers, project cost control, corrosion monitoring and inspection, sharing of knowledge across the industry, and the adoption of common standards. Steve Paterson detailed key future challenges including an ageing infrastructure, marginal field development, dealing with high pressures and temperatures, extreme environmental conditions, materials for sustainable energy together with the development of artificial intelligence, commercial acumen and a greater awareness of risk/probability.

Following the presentations, the 45+ attendees participated in a question and answer session which particularly discussed the way to attract young people into the industry who will be innovative and creative and use good judgement in the use of corrosion protection.

On 9th February, the Branch met to enjoy a technical presentation entitled ‘Corrosion Inhibitor Testing – The Journey’ given by George Winning; corrosion specialist for Element Materials Technology.

George began his presentation with a quick review of the 70 year history and development of chemical products, the study of the inhibitor mechanisms, together with some of the key characteristics an inhibitor should have, to ensure that they will work for a particular oil and gas system.

The presentation looked at the many tests that are needed to be carried out to identify the correct product for a system, and how a set of tests may vary between an application in low oil cut systems through to high water cut systems, and the different tests required for gas systems. George made particular reference to the problems associated with the effects of flow, the difficulty of achieving full inhibition where ‘under deposit corrosion’ (UDC) is occurring, the problem in combating ‘preferential weld corrosion’ (PWC) and the specific techniques required to combat ‘top of line corrosion’ (TOLC).

He then summarised ‘The Journey’ to be made for success, including review of the application, design of the test program, the selection of performance tests, field testing, re-evaluation and performance monitoring. After negotiating a question and answer session with the attendees, Committee Member, Polina Zabelina thanked George for his comprehensive review on all that needs to be considered, and invited all present to enjoy the traditional hospitality of the London Branch.

Details of forthcoming Branch technical meetings can be found on the ICorr website and in the Diary Date page of Corrosion Management, and are held at Imperial College Skempton Building, at 18.00 for an 18.30 start. Enquiries can also be sent to icorrlondon@gmail.com
