- Piping and equipment modification plans
- 3D models
- P&ID to piping layout, structural drawings and piping isometrics (all from 3D model)
- P&ID as-building — using an existing set of the facility P&IDs I follow every pipeline in a facility verifying that the plans show what is actually there and correcting errors
- Wiring interconnection drawings for facility control panels developed at an electrical engineer's direction
- Red-line mark-ups drafted for many other kinds of oil and gas facility drawings (P&IDs, piping layout, vendor equipment modifications and electrical interconnections)
- Piping model of exchanger installation
