One of our blue-chip clients undertook major modification to their plant.
I&E Systems were engaged to deliver the new DCS for the project. Our involvement began with the initial Identification Study in 2007 through the remaining study phases to the current Execution phase.
I&E Systems provided control system engineering related to the DCS Works including the existing Honeywell DCS and the new Yokogawa CentumVP DCS. Overall, 23 DCS and network cabinets were designed, constructed and tested for the hardwired I/O nearing 2000 points. The new system also has interfaces to existing systems for production reporting and optimisation.
Graphics were produced based upon ASM principles which provided the operations group with a vastly reduced set of mimics compared to traditional methods. The new system integrates with the existing DCS such that operations are able to operate the new plant and view the existing plant for areas of commonality.
Accuracy and detail in the DCS wiring design from using the DAD software package played a significant role in reducing errors and changes between design and construction. The measure of this success was the error-free migration of existing I/O in the Reagents area from the existing DCS to the new DCS in a short shutdown duration.
As-building was completed quickly, as all changes had been managed in DAD throughout the project site phase. The DAD software package also played a central role in the delivery of error-free software by associating software points with design documentation such as hardware designs, functional specifications, P&ID’s, technical queries and change requests.
The DCS was delivered on time and was under budget.
