Our quotes are based on equipment and Instrument count not actual P&ID count for the facility. It is in our experience during a P&ID walkdown that P&ID’s become very congested when the appropriate information is added, as a recommended practice there should only be three or four pieces of equipment on one P&ID. Most of the time existing P&ID’s would have to be split to accommodate the new information. Also Secondary headers (steam, instrument air, natural gas, etc) will have there own P&ID’s with secondary connections to the process P&ID’s. The process P&ID’s will contain all relevant piping and instrumentation / controls for that piece of equipment(s) and then connect to the corresponding P&ID.
*Open Range's definition of a complete P&ID walkdown: “Verify all components which would include equipment and its associated nozzles, field instruments (excluding control functions), and piping which encompasses all pipe sizes and tubing runs. This would include all Primary – process piping and all Secondary piping (sometimes called utility piping)”
Due to our experience in finding that in many cases there are different symbol representation between P&ID’s it would be recommended to update all symbols including piping, equipment and instrumentation to match current facility legend sheets or ISA / PIP standards.
**Open Range Applications, LLC partners up with Open Range Engineering Services, PLLC to offer P&ID walkdown services, with over 25 years of field experience, Open Range can get it done right the first time. Not only can we walk down P&ID's but we can help get the emergency plot plans updated, process flow diagrams created, electrical classifications up to date and any other design or engineering drawings your facility may need.
With our in house conversion tool, we can import your existing P&ID's to the Visual Information Management software at a fraction of the cost compared to redrawing them into the software. At the time of import we can also split the drawings and pick up any additional red lines that may exist from the P&ID walkdown. Ask for a quote today and see what Open Range can do you for you.
