5 Levels of Risk Analysis. How many do you have?

5 Levels of Risk Analysis. How many do you have?

Mission Impossible, Why new RBI?
Equipment risk analysis is a core activity in plant risk management. Many spears were broken about prioritizing individual equipment monitoring and risk controls, to ensure its safe and reliable operation. We have arrived to the capability of performing risk assessments at 5 levels of depth. This multi-level approach enables a two-fold cost/benefit optimization: analysis cost is minimized and a risk cost analysis is enabled where required. This article shows applications to pressure equipment inspection planning (RBI). Drivers for multi-level RBI We naturally recognize two levels of approach to engineering problems: First-pass system screening for criticalityIn-depth analysis of critical elements only This sequence of tasks well optimizes time and efforts. The only precaution is not to get locked into the screening step (1) solely. Critical objects require a detailed analysis (2)…

FEA Nocturne – Time for Change?

FEA Nocturne – Time for Change?

Mission Impossible
Finite Element Analysis (FEA) is indispensable for visualizing a structural response to a wide spectrum of loads and design options. FEA enables plotting a stress/strain field for complex geometries, which is not feasible to do by hand calculations. It appears that FEA services lose popularity in our industry. Here I share my thoughts why this happened, and conclude on how to improve the FEA practicality and to embed it into the plant asset management process. Here we will start from deep technical matters and end up with bright future perspectives. Tips are for FEA practitioners only. Fig. 1. FEA analysis loop, as it should be Introduction - What is FEA at a glance? Structural Mechanics force, displacement and stress calculations are well suitable for simple, idealized objects like beam frames…

Online IDMS/RBI software made by integrity engineers

Online IDMS/RBI software made by integrity engineers

Mission Impossible
Did you ever wonder whether Integrity engineers can make a good IDMS platform by themselves? Other than just an RBI spreadsheet or MS Access database? Would that be different to the IT market offers? Triple YES! The below text outlines our new concept for a new level of the software user friendliness. It originates from our many years exposure to integrity engineering workflow and from many attempts to automate it. The AIM data® is online and ready to use. The Need for the New In many years of RBI exposure, we observed three major data management gaps: As soon as the number of inspection data grows, spreadsheet based analysis capability becomes limited. Just too many numbers, and too much copy-paste work. Spreadsheets work up to a point.What if we try…

3 Pressure Relief Devices for Integrity Engineers

3 Pressure Relief Devices for Integrity Engineers

Mission Impossible, Uncategorized
Caring about plant integrity is a busy and stressful work. Human psychology is such that maintaining current environment is confused with staying in a comfort zone. Albeit this zone may not be comfortable at all (same outcomes from same contractors, same burden of responsibility and document management, same questionable risk management confidence). If you wish to change this environment, consider the holistic improvement of integrity tasks: 1. Know your Risk Cost and Safety Implications One thing in the back of your mind might be: 'How confident are we about what we do for the equipment integrity and safety'? - an obsessive question. Consider all those people going on site and doing the hard work there. And also - all the resources being spend over a facility life. Looking at the…
