Beyond the core DEP documents, the standard ecosystem includes several supplementary tools:
Standard Drawings: Blueprints for standardized components like compressor designs and piping fittings.
MESC (Material and Equipment Standards and Code): A coding system linked to DEPs that identifies specific pipes, valves, and equipment types.
Standard Requisitions & Forms: Templates used by contractors and manufacturers to ensure compliance during the procurement phase. 4. Implementation and Compliance
The use of DEPs is typically governed by a distribution system and specific licensing agreements.
Contractor Responsibility: Manufacturers and contractors are responsible for adhering to DEP requirements for fabrication, inspection, and performance testing.
Latest Versions: Engineering projects are required to use the latest versions (e.g., current version 39) along with all applicable amendments and attachments.
Local Flexibility: While DEPs set a global standard, they allow for flexibility where local regulations or specific site conditions require deviations. 5. Essential DEP References (Examples) Description DEP 31.38.01.11

Shell Design and Engineering Practices (DEPs) are proprietary technical standards used to ensure consistency, safety, and efficiency across Shell's global operations. These standards provide high-level specifications for the design, construction, and maintenance of various facilities.
Because DEPs are proprietary and subject to strict confidentiality agreements, a "complete text" is typically only available to authorized Shell employees, nominated contractors, or licensed manufacturers. However, a standard DEP document follows a structured format that you can use as a template for drafting internal technical specifications. General Terms and Conditions for use of Shell DEPs Online.
Shell Design and Engineering Practice (DEP) standards are internal technical guidelines that govern the design, construction, operation, and maintenance of Shell facilities globally.
