5 Steps to Optimal Integrity and Performance Page 5 To create and manage the asset register a number of engineering documents are required and need to be as-built, to a high standard, and correlate with site tag numbering. The P&IDs (Process and instrumentation Drawings) and E&IDs (Electrical and Instrument Drawings) form the majority of the equipment required for the asset register and help to demine the taxonomy and application of the equipment. In addition to this the Cause and Effect Drawings are critical to determining the safety function of the instrumentation and end elements and are particularly useful when determining which equipment are safety critical elements when it comes to the shutdown hardware barrier. The EX-register is also critical to the registration of equipment and the identification of safety critical equipment as per the ignition control hardware barrier. Equipment data sheets and OEM (Original Equipment Manufacturer) data are critical to the data scraping for bills of materials. This becomes extremely difficult and much more costly once the project phase is over to get this information and retrospectively populate it through data requests with the OEM. add energy have developed a software library for BoMs in order to auto match, but this requires the model and manufacturer to be populated in the asset register.
