Risk Assessment

AI IMD (formerly Bass-Trigon) is a leading developer of risk assessment solutions for the natural gas and hazardous liquids pipeline and facilities industry. The following list identifies three levels of algorithms or risk methodologies provided by AI IMD for supporting pipeline and facility risk management. All approaches are supported by a combination of ASME, API and NACE standards and RP’s, as well as subject matter expertise and knowledge from the AI IMD user community.

• Level 1 - Threat Screening: This methodology examines pipelines and facilities and determines if a threat is or is not present. Level 1 is typically used to efficiently pin-point areas where threats exist and further assessment is advised.
• Level 2 - Indexing: This methodology is a well accepted approach for scoring threats and consequences for pipelines and facilities. Level 2 is typically used to rank assets for on-going assessment, mitigation and repair investment.
• Level 3 - NewGen Quantitative: This methodology is a relatively new approach that can rank assets and more effectively assess the impact of assessment, preventive and mitigation activities. Level 3 Quantitative is capable of providing time to failure and probability of failure values, and monetized consequences.
