3. Co-Organized by CCPS and IBRAM
Use of the Bowtie Tool to Develop Regulatory Standards Focusing on Process Safety and Integrity
of an Ideal Pumping Systems
• New application of Bow tie to develop Company
Technical Standards based on Process Safety
• Using of a Risk Analysis to prioritize requirements on
the Standards (RBPS principle)
• Bow tie permits a visual presentation, barriers
structuring, and identification of escalation factors
controls compared with other techniques as HAZOP,
FMEA, etc.
• Case study in major pumping systems in a large
industry of the mineral sector.

Conclusions
• Risk Based Standards
• Standards focused exclusively on critical safety
barriers of assets
• Understanding of barriers degradation and needed
controls
• Methodology goes beyond the risk analysis and bring
requirements based on international references to
support design, installation and maintenance of the
assets.
