The bowtie methodology is designed to provide the right level of detail to facilitate understanding and risk-based decision making, without oversimplifying a process.
This course reflects current industry good practice (CCPS Bow Tie In Risk Management – A Concept Book for Process Safety) and will help you better understand the methodology and how to conduct a bowtie analysis effectively in the management of process safety and environmental and asset integrity scenarios.

Bowtie Analysis for Catastrophic Explosion in the CO2 removal system – Case Study
This course will help you better understand the methodology and how to conduct a bowtie analysis effectively in the management of process safety and environmental and asset integrity scenarios.
The course covers as example an incident related to the sudden increase in pressure of a 20,000 ton liquid ammonia storage tank caused the roof to shell connection to rupture and the spread of ammonia vapor in the concentration of approximately 30-100 ppm in the region’s atmosphere in a radius of approximately one kilometer.

Bowtie analysis for methanator feed preheater flange leak and explosion – Case Study
This course will help you better understand the methodology and how to conduct a bowtie analysis effectively in the management of process safety and environmental and asset integrity scenarios.
The course covers as example an incident related to the corrosion in the semi lean amine (a-MDEA) line to CO2 absorber tower, in combination with other factors that lead to the explosion of synthesis gas due to back flow from the tower.

Bowtie Analysis for Primary Reformer Firebox Explosion Case Study
This course will help you better understand the methodology and how to conduct a bowtie analysis effectively in the management of process safety and environmental and asset integrity scenarios.
The course covers an example of a top fired primary reformer which exploded in an ammonia plant. Incident investigation concluded that the direct cause of the accident was the introduction, by error, of a large amount of fuel gas through unlighted arch burners.
