Shell Design and Engineering Practices (DEPs) are a comprehensive set of internal technical standards used by Shell and its authorized partners to ensure consistency, safety, and efficiency across global energy operations. These documents provide the "gold standard" for engineering design, procurement, and construction in oil, gas, and chemical facilities. Core Purpose and Objectives
The primary goal of Shell DEPs is to achieve maximum technical and economic benefits through standardization. Key objectives include:
| Feature | International Code (e.g., ASME, API) | Shell DEP | | :--- | :--- | :--- | | Status | Consensus standard | Proprietary company standard | | Stringency | Minimum legal/industry baseline | Higher, risk-based requirements | | Corrosion Allowance | Often 1.5 – 3 mm | Typically 3 – 6 mm (depending on service) | | Non-Destructive Testing (NDT) | Random spot checks may suffice | 100% radiography on critical welds | | Material Impact Testing | -29°C often acceptable | -46°C or lower for many services | | Documentation | Standard MTRs | Full traceability + VDDR + 3rd party witness | shell dep standards

DEPs require vendor documentation (drawings, calculations, quality plans) at specific milestones (e.g., 30%, 90%, Final). Late submission triggers stop-work orders. Shell Design and Engineering Practices ( DEPs )
