Corrosion management (CM) is a rather new concept and expertise. Its origins go back to early 2000's. The CM concept emerged from the UK's offshore oil and gas industry; from where the author also started his professional career.
Due to this newness and a vast multitude of application benefits, there has been a constant growth in demands for the provision of CM awareness, training, expertise and consultancy year after year.
The author has so far compiled a total of four CM books and this one is the last in the series. It is also the most comprehensive among the four books, with a greater emphasis and focus on CM field implementation.
Therefore, if one intends to implement CM across their asset(s), then this book could provide them with the required advice, instructions and guidelines on proper CM field implementation for both hydrocarbon and non-hydrocarbon industries.
The book covers subjects from how to define the scope of work to report writing and communicating the latest integrity findings.
It is written in a simple and jargon-free language and intended for various disciplines including: corrosion and integrity engineers, inspection engineers, pipeline engineers, process engineers, maintenance engineers and asset integrity managers

Digitalization is the use of digital technologies and digitally-enabled approaches to enable or improve business models and processes. The use of remote tablets to capture inspection data in real-time and the use of streaming video are key examples of digitalization. The addition of sensors to monitor the health of an asset is a component of enabling a digital twin concept, which is enabled with historical, real-time and forecast data. This document presents current use cases on the use of digital twin platforms to visualize assets and provide context for operational data. The use of hyperspectral sensors to help enhance the digital twin environment adds lifecycle features that enable more efficient condition monitoring. An overview of the BIM (Building Information Modeling) service supporting the digital lifecycle of 3-D/2-D model integrations will be discussed. This will also include the use of AR/VR devices including Microsoft’s Hololens and the delivery of ‘model load packages’, which allows the user to view the various models required to integrate with Hololen’s features. The combined use of augmented inspection reporting and corrective maintenance instructions allows for a streamlined inspection approach through the use of in situ sensors and mobile inspection campaigns.
The recognized international codes, such as ASME , API, BS provide design and fabrication guidelines for various equipment used in industries viz. pressure vessels, piping and storage tanks. However, the fabrication standards do not address acceptability of the equipment on detection of any deterioration; once put in to the operation.
The engineering assessment becomes essential when flaws such as “leakage”, ‘metal loss’ or ‘linear indications’ are detected during routine inspections. Sometimes, observed damages or flaws, do not meet the definition criteria as per assessment steps given in the international standards of fitness for service. In order to asses such damages, a structured engineering approach based on experience and judgment would help in such situations.
Describing the structured engineering assessment approach, this paper discusses a case study on typical ‘hydrogenation reactor’ that displayed micro-level leakage. Until 2015, the reactor often leaked during service prior to the assessment. This approach using various NDT methods, microstructural examination and structured engineering analysis identified the problem of dilution of base metal with welding that was leading to inter dendritic corrosion at micro level. The structured engineering analysis paved the forward path by which the reactor could be operated without any unscheduled outages since then after providing improved welding procedure.
