Shell Dep Standards -

Understanding the numbering system is critical. A typical DEP document number looks like: DEP 31.22.00.10-Gen

Let's break it down:

Shell DEP Standards are a comprehensive collection of technical documents that define the "how" of designing, engineering, constructing, operating, and maintaining facilities. They consolidate Shell’s century-long experience, lessons learned from incidents, and evolving regulatory requirements into a unified set of mandatory practices. shell dep standards

Unlike generic international codes (such as ASME, API, or ISO), DEPs take a prescriptive and interpretive approach. For example, while API 650 might give a range for tank design, a Shell DEP will specify exactly which clause to use, what safety margin to apply, and how to inspect the weld—often exceeding the base code requirements.

A script should never assume the execution environment is pre-configured. Dependencies must be declared, checked, and isolated to ensure the script behaves identically on a fresh machine as it does on a development machine. Unlike generic international codes (such as ASME, API,
