In stock
Unit overview
This set of 3 units introduces safety and risk management. Unit 10 explains how to carry out quantitative risk assessments (QRAs) focusing on assessment of oil and gas or process plants. The unit explains how QRAs are used and the input they have into risk management. Unit 11 explains how to carry out frequency assessment for a typical oil and gas or process plant. The assessment consists of a parts count and event tree analysis. The unit explains how the frequencies of releases and their outcomes (e.g. fires, explosions, etc.) can be calculated. Unit 12 explains how to carry out a consequence assessment for a typical oil & gas process plant. The assessment consists of a mixture of physical effects modelling and vulnerability analysis. The unit explains how the consequences of releases can be quantified and how to predict the impact of those consequences.
