Extensive experience in Natural Gas Process Plants
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 oils and gas facility drawings (P&IDs, piping layout, vendor equipment modifications and electrical interconnections).
