Targeted at upstream oil and gas environments, Honeywell’s Strategy-A 4.0 is an effective tool for evaluating cracking of steels in wet H2S service environments. It enables significant cost and time savings by performing accurate characterizations of pipeline environments, estimating crack growth potential and reducing response time in materials selection and reliability assessment for sour pipeline operations.

Measuring Steel Cracking Susceptibility in Sour Pipeline Environments

Steels are evaluated in Strategy-A 4.0 for susceptibility to sulfide stress cracking (SSC), hydrogen induced cracking (HIC) and stress oriented hydrogen induced cracking (SOHIC) mechanisms in sour pipeline environments. The system provides access to a comprehensive knowledge base containing information about carbon steels and requirements for HIC, SSC and SOHIC resistant behavior.

Strategy-A 4.0 utilizes data and rules from laboratory research stemming from a comprehensive Joint Industry Program (JIP), field experience, literature and domain expertise to improve steels evaluation and pipeline inspection. Analysis includes determination of environmental severity to cause cracking, compatibility of steels used in construction, fabrication techniques and risk assessment in terms of crack growth potential and prioritization of inspection. Its embedded JIP data-based rules and extensive domain expertise assist in accurate quantification of cracking susceptibility.

​Evaluation of steels in Strategy-A 4.0 begins with ranking of the oil and gas pipeline environments in terms of hydrogen charging efficiency to determine an Environmental Severity Factor (ESF) for HIC, SSC and SOHIC. It also ranks steels based on material parameters such as composition, micro structure, heat treatment and strength/hardness to determine the material resistance factor (MRF) representing the steel's resistance to HIC, SSC and SOHIC. Strategy-A uses a combination of 15 parameters to determine individual material ranks.

Assessment of reliability of the continued use of a specific segment of oil and gas pipeline equipment and material is enabled through determination of a Crack Growth Factor (CGF). The crack growth factor also helps pinpoint potential weak points in equipment morphology. 

The comprehensive information contained in Strategy-A 4.0 allows users to

  • perform accurate characterizations of pipeline environments on the basis of environmental severity;

  • evaluate materials on the basis of metallurgical, mechanical and micro structural parameters;

  • estimate crack growth potential in pipelines and

  • perform effective risk assessment.
