Shell Dep Version 46 !link! -

Shell Design and Engineering Practices (DEPs) are the backbone of technical integrity for Shell’s global operations, and Version 46, released in February 2022, represents a key update in this ongoing evolution. These standards provide a uniform platform for engineers, contractors, and suppliers to ensure safety, reliability, and cost-efficiency across complex oil, gas, and chemical projects. Core Purpose and Scope

3.2. Piping and Valves (Series 20)

• Material Specifications: Updates to carbon steel specifications to address issues regarding Hydrogen Induced Cracking (HIC) and Sulfide Stress Cracking (SSC) in wet sour service environments.
• Valve Criticality: Refinement in the categorization of valve criticality levels, impacting the frequency and type of testing required during Factory Acceptance Tests (FAT).

• Version 46 introduces glob patterns, lazy sourcing, and robust integrity checks.
• Installation is simple via curl, brew, or winget.
• Performance and security are significantly improved over earlier versions.
• The tool is production-ready and LTS-designated.

1. Piping and Valves

DEPs are famous for their stringent requirements regarding piping classes. Version 46 introduces refined specifications for materials handling sour service (environments with hydrogen sulfide). It likely includes updated references to NACE MR0175/ISO 15156, ensuring that metal components are resistant to sulfide stress cracking. Shell Dep Version 46
