The job

This project was a great reminder of how many rigs out there still don’t have proper as-builts or layout drawings, and how valuable it is for teams to finally get clean, accurate documentation in place.

We delivered a full set of API RP 500 hazardous area classification drawing packages for a drilling company’s entire rig fleet. We went rig-to-rig, measured each unit to build accurate layouts (none existed), identified all hazardous areas, and produced complete drawing packages. The sample drawing above shows what you can expect when you work with us.

If your operation needs as-built drawings, rig layout packages, updated documentation for compliance, or anything in this style, reach out. We’ve got the capacity and can turn this work around quickly.

What we did

  • Rig-to-rig measurement trips across the fleet
  • Accurate rig layouts drawn from field measurement, where none existed
  • Class I, Division 1 and Division 2 areas identified and drawn per API RP 500
  • Complete drawing package per rig, plan and elevation views
