Retrospective future proofing of a copper mine: Quantification of errors and omissions in ‘As-built’ documentation
MetadataShow full item record
© 2016 Elsevier LtdThe electrical instrumentation control systems (EICS) ‘As-built’ documentations of a copper mine were found to possess a significant errors and omissions, which hindered the asset owner's ability to undertake effective and efficient operations and maintenance. A Systems Information Model (SIM) was used to retrospectively create a connected system to ensure all physical equipment and the associated connections that were constructed are modelled in an object-orientated database. In creating the SIM, the existing errors and omissions in the ‘As-built’ documentation were quantified, and cost savings that could be achieved for a future planned copper mine, with a similar design, were identified. The limitations of using conventional computer-aided-design (CAD) to design and document EICS are discussed. It is recommended that retrospectively creating a SIM can provide owners and operators with significant productivity benefits as well as ensure the asset's integrity. The case study presented provides asset owners and operators with the empirical evidence to challenge conventional thinking surrounding the design, engineering and documentation of EICS using CAD and alternatively consider the use of SIM.
