There is a gap between the Integrity management systems used by companies to manage their assets and the needs of the CP engineer. Integrity management systems do not fully meet the needs of the engineer responsible for corrosion as they do not provide access and visualizations of all the data the engineer needs to make fast and informed decisions. There is also often no easy way to see the trends in the data, or easily access the relevant video and photographic data also recorded during the survey.

Data from surveys is normally contained in reports and EXCEL spreadsheets often with different measurement locations and inconsistent naming of the locations between reports. In this paper a system is introduced which enables engineers to manage and visualise in 3D CP survey data and provide access to all the relevant information through a 3D visual interface to any member of the teams. The software gives the engineer the ability to visualize in 3D the historical and predicted CP protection on the structure and the status of the anodes in the CP system. It also provides information on long term trends in the survey data.

By integrating the corrosion data with a simulation model a “digital twin” of the structure can be created to make predictions of the present and future protection of all parts of the structure. For example the engineer can easily use the software to systematically monitor the differences between the model predictions and survey data to identify anomalies and give early identification of problems which will require action.

The paper will describe the system developed and present applications of both the 3D corrosion data visualisation and the simulation based digital twin

The continuous improvements in the Oil&Gas Industry to deal with reliability and maintainability objectives, higher operational reliability, improved safety, and emergency readiness for potential risk of unexpected events have led the Offshore Companies to be in the forefront of development of design and analysis methodology for integrity assessment and safety operation. The architecture of an integrated model targeting the major residual risks to the asset, new generations of internal and external inspection techniques, real-time monitoring sensors, material degradation prediction related to the actual and future operational conditions and machine learning methods are, as identified from the experiences of the authors, the new frontiers for the Pipeline Integrity Management. The advance in automation process to build pipeline digital twin, looking at new predictive and diagnosis tool by advanced FE models allows not only thinking defensively but also in taking an aggressive position toward safety and asset optimization. Plenty of attention was devoted to the 40 years of pipeline integrity assessment through which the engineering assessment takes advantage from inspection and operational data. Suite of services for an integrated solution including ad-hoc engineering and repair system readiness have been identified as the main pillars for best-in-class Operators. Case histories and integrated solution to ensure satisfactory performance and safety have been presented.

Storage tanks are the primary means for storing large volumes of liquids and gaseous products. Metal
loss from internal and external corrosion can reduce the service life of a tank. It is important to maintain
the integrity of steel storage tanks for safety, economic, and environmental reasons.
Saudi Aramco implemented three different scenarios of cathodic protection (CP) during bottom plate
replacement for three typical tanks. The tanks’ bottom plates were replaced based on thickness
measurements and visual inspection that revealed severe corrosion from soil. The main reason for
such corrosion was due to the asphalt layer underneath the tank. It was considered during the
replacement of the bottom plate to provide a reliable external (CP) and leak detection system. The
purpose of this paper is to demonstrate the experience gained from executing CP upgrades, and to
provide the best option to ensure integrity, cost saving and fewer shutdown periods.
