Risk Based Asset Integrity Assessment and Control of Onshore and Offshore Systems

The course has the focus on delivering knowledge on risk-based asset integrity assessment and control (RBAIA&C) for engineering and technical professionals from different operational disciplines (e.g. mechanical, structural, chemical & process, etc.) who have engineering/technical/managerial background

The asset integrity assurance techniques in relation to physical assets (i.e. static process equipment, e.g. piping, pipelines and structures; and rotating machinery, e.g. pumps, turbines, etc.) will be discussed in relation to design, operational and technical integrity perspective.

The importance of minimizing human factor related challenges and role of asset performance variability minimization methodologies with relevant case studies will be explained. Risk based analysis principles and development risk matrices with special consideration to probability of failure (PoF) and consequence of failure (CoF) assessment  will be presented. 

Operational efficiency (OE) improvement via lean thinking and use of digitalization & artificial intelligence (AI) will be explained. Basic corrosion and erosion mechanisms that need to be considered in a risk-based inspection (RBI) program development will be explained. Reliability centered maintenance (RCM) analysis together with failure mode effects analysis (FMEA) and criticality analysis (FMECA) will be presented.

Also, the functional failure consequence classification approach for rotating machinery will be presented. Use of conventional inventory control approaches for spare parts assessment and control as well as consequence classification based on functional hierarchy and risk based spare parts assessment and control will be discussed.
