Natural Gas Transmission

IMD provides a fully integrated integrity management solution for natural gas pipeline companies following the criteria of ANSI B31.8S and OPS regulations. We offer the full spectrum of the integrity management solution including HCA (high consequence area) identification through dispersion analysis, baseline assessment plan development, data integration and alignment, threat and consequence analysis, software licensing, integrity management program documentation, data mining and other engineering services.

Integrity Management Workflow Based on Latest Version of ASME B31.8S

HCA Identification (top of page)

• RiskCAT is IMD’s application that supports the HCA identification process,
• Identifies pipeline sections that could affect HCAs as defined in US OPS regulations,
• Calculates impact areas based on gas release characteristics,
• HCA data is integrated into our IMP software (or any other software of your choosing) for baseline plan management.

Data Integration (top of page)

• IMD provides data integration services for IMP software or other client implemented systems,
• Data integration capabilities includes both pipeline and facility (compressor, regulator, storage, etc.) data,
• Services are compatible with PODS, ISAT and other proprietary data models,
• Any type of relational data can be managed in IMP application,
• IMP application is optimized to manage performance data including in-line inspection, corrosion, direct assessment and pressure test data, etc.,
• Full multi-user capability allows multiple users to manage, integrate and analyze data,
• Ad-hoc dynamic segmentation optimizes individual threat and consequence analysis,
• Manages multiple reference systems and rubber bands data sets for accurate data alignment.
• Reference systems are not restricted to a virtual model. Any reference system can be aligned with any other named reference.
• Drawing and graphical analysis tools allow effective analysis of integrated data.

Threat and Consequence Analysis (top of page)

• Threat and consequence analysis can be performed at point or section locations. Ad-hoc dynamic segmentation allows analysis to be conducted at any user defined interval,
• Data mining capabilities allow knowledge patterns to be revealed, thereby supporting algorithm development and implementation,
• Ad-hoc mathematical expression and rule builder supports qualitative, semi-quantitative and quantitative risk analysis of all threats,
• Graphical analysis tools allow for effective analysis and knowledge discovery.

Integrity Assessment Plan (top of page)

• Rules engine allows creation of rule sets to schedule integrity assessment options,
• Baseline assessment plan is developed and managed based on threat and consequence analysis,
• External, internal and SCC (stress corrosion cracking) direct assessment is fully supported by data model and analysis engines,
• Capable of managing both performance and prescriptive-based programs,
• IMD provides documentation support for the resulting integrity management program document.

Repair and Mitigation (top of page)

• Repair scheduling and criteria are managed,
• Manages prioritization and inspection of defects,
• Resulting mitigation activities are tracked through the application,
• The application manages the effective time of all activities, ensuring that the integrity assessments only include data that is relevant for the proper window of time.
