A large portion of the site had been changed and adjusted during initial construction and subsequent operation. BRE’s job was to verify and record the existing site infrastructure and update the P&ID drawings. This required a lengthy site visit to walk the whole plant and record each and every piping connection.

The P&ID update was required to improve the safety procedures on site. In order to properly isolate a piece of equipment, all inputs and energy sources must be known and neutralised. In a complex plant this can be difficult without an up to date P&ID.


  1. Initial consultation and site review
  2. Full processing plant review
  3. Complete set of updated P&ID drawings
