Oil and gas projects generate some of the most technically demanding CAD drawing requirements of any industry. P&ID diagrams must comply with ISA and ISO standards. Piping layout drawings must integrate accurately with equipment models. As-built documentation must be maintained throughout the asset lifecycle. This guide explains what CAD outsourcing looks like for the oil and gas sector.
The main drawing types required on oil and gas projects include P&ID drawings showing the process flow, instrumentation, and control systems. Process Flow Diagrams providing a higher-level process overview. Piping layout drawings showing the physical routing of pipework. Equipment layout drawings. Isometric drawings for individual pipe runs. As-built drawings updated throughout construction and operations. Electrical and instrumentation drawings. Hazardous area classification drawings.
P&ID drawings are the most critical and complex drawing type on oil and gas projects. They must comply with ISA 5.1 and BS EN ISO 10628 standards and be maintained as living documents throughout the life of the plant. Outsource CAD has produced over 500 P&ID drawings for oil and gas operators and EPC contractors and has extensive experience working to operator-specific standards and symbol libraries.
P&ID tag extraction captures instrument and equipment tag data from drawing sets and consolidates it into a structured database for maintenance management and compliance. Outsource CAD provides tag extraction as a standalone service, delivering structured spreadsheets or databases formatted to your CMMS requirements.
Maintaining accurate as-built drawings throughout plant construction and subsequent modifications is a regulatory requirement and an operational necessity. Outsource CAD provides ongoing as-built drawing updates from redline markups, incorporating site changes quickly and accurately.
Large oil and gas projects generate high volumes of redline markups throughout construction. Outsource CAD has completed over 1,600 redline markups on oil and gas projects and uses shared trackers to give clients complete visibility of markup status.
