Pipeline failures can trigger domino effects, increasing risks from jet fires and erosion. This study analyzes accident data and develops a model to predict domino effect probability, crucial for realistic pipeline risk assessments.
Area of Science:
- Engineering
- Risk Assessment
- Industrial Safety
Background:
- Parallel pipelines are common over long distances due to corridor constraints.
- Releases from one pipeline pose significant risks to adjacent ones.
- Domino effects include erosion from fluid-sand jets and thermal hazards from jet fires.
Purpose of the Study:
- To analyze historical accidents involving parallel pipelines.
- To investigate and understand domino effect sequences.
- To develop a mathematical model for estimating domino effect probability.
Main Methods:
- Survey of past pipeline accidents.
- Analysis of domino effect scenarios.
- Development of a mathematical probability model.
Main Results:
- Domino effect probability depends on hole location, jet characteristics, pipe diameters, and distance.
- The model shows probability decreases with source pipe distance/diameter and increases with target pipe diameter.
- Calculated failure frequency for target pipes is higher than individual frequencies.
Conclusions:
- The developed model provides a method to estimate domino effect frequency.
- This enables more realistic risk analysis for parallel pipeline systems.
- Understanding domino effects is vital for enhancing industrial safety and preventing cascading failures.
