Shell Dep Standards Page
Websites offering "free Shell DEP download" are often selling outdated (5-15 year old) versions, which are dangerous to use. Using an obsolete DEP can lead to a failed audit or an unsafe design. Always verify revision status via the official numbering (e.g., Rev. 4, Rev. 5, etc.).
Do not rely on the user having a specific shell library (like shunit2 or 严格的bash) installed globally.
Sourcing Strategy:
# Use absolute paths relative to the script location SCRIPT_DIR="$( cd "$( dirname "$BASH_SOURCE[0]" )" &> /dev/null && pwd )"
source "$SCRIPT_DIR/lib/logging.sh" source "$SCRIPT_DIR/lib/validators.sh"
DEP (Design and Engineering Practice) documents are the proprietary technical standards used by Shell Global and its subsidiaries. They act as a "rulebook" that sits on top of international standards.
The Hierarchy of Standards: To understand DEPs, you must understand where they sit in the engineering hierarchy: shell dep standards
The Purpose: DEPs ensure that a Shell facility in Nigeria operates with the same safety integrity and reliability as a facility in the Netherlands. They standardize design, materials, and construction methods to minimize risk and optimize lifecycle costs.
