The primary objective of DEPs is to ensure that all assets—ranging from deepwater offshore platforms to liquefied natural gas (LNG) plants and refineries—are designed and operated to ensure maximum safety, high availability, and optimal lifecycle costs. The Standard Hierarchy
These standards go beyond international standards (like ISO, API, ASME, or ASTM) by providing specific, actionable requirements tailored to Shell's operational philosophy. Key Components of DEP Standards
When it comes to internal dependencies, the modern approach is . Instead of a monolithic 1000-line script, code should be broken into modules (e.g., common.sh , logger.sh , intent.sh ). This reduces duplication and isolates functionality. However, sourcing these files manually is error-prone. This is where dependency management frameworks come in. shell dep standards
: Guidelines for fire protection, insulation, and onshore/offshore coatings .
A standard is incomplete without verification. Testing has historically been the Achilles' heel of shell scripting. The industry standard is . The primary objective of DEPs is to ensure
Conversely, those who treat DEPs as "suggestions" find themselves in dispute resolution, facing back-charges, or removed from Shell’s approved vendor list.
The DEPs are exhaustive, spanning nearly every engineering discipline required for large-scale energy infrastructure: Instead of a monolithic 1000-line script, code should
Shell DEPs are proprietary documents. Access is typically provided to Shell employees and contractors working on authorized projects. The is the official repository for these documents, ensuring compliance with the most current standards. Conclusion
This category covers both static equipment (such as pressure vessels, heat exchangers, and storage tanks) and rotating equipment (including centrifugal pumps, compressors, and gas turbines). The standards ensure equipment is robust enough to handle severe operating envelopes. Electrical and Instrumentation (E&I)
This is the most practical challenge for industry professionals. You cannot download them for free from public websites.
Your fabricators and vendors must be DEP-aware. Include DEP clauses in your purchase orders. For a valve vendor, provide DEP 83.00.00.10-Gen (Valves) alongside API 598. Host a "DEP kickoff meeting" for critical suppliers to clarify inspection hold points.
