Simplify Your DCIS and Reduce Total Plant Construction Costs

Summary:
New methods lower total construction costs
JDI Contracts Inc. recently developed a new methodology for DCIS implementation utilizing bussed technology and new construction techniques. Significant savings are possible in several project areas, including engineering, construction, startup, overheads, and long term plant operations for any size or type of process facility.

Take control of your project and your process
Smart technology cuts the number of hard field terminations while providing a system with more data and control point access than traditional field cabinet systems. Fewer terminations mean less cable, conduit, and tray, requiring less engineering and installation labor, resulting in a shorter schedule and lower costs. More information means quicker response, better predictive ability, and more feedback regarding your process. Together it means a more effective system at a lower cost.

Economic Impact of Digital Technology on New Plant Construction

Summary:
This study compares two potential implementations of a Distributed Control System (DCS) on a Greenfield 600 MW supercritical power plant installation. The “Traditional” installation utilizes dedicated cables to hardwire non-intelligent field devices to input/output (I/O) cards. The Digital Bussed Plant (Bussed) installation uses bussed (I/O), high speed field communications networks, and intelligent or “smart” field device technology to simplify construction. Costs were estimated for both implementation approaches in five categories: system selection, engineering, construction, startup, and overheads. Potential operating and maintenance (O&M) cost savings were also estimated.

Economic Impact of Digital Technology on Wet Scrubber Construction

Summary:
This study compares implementations of a Distributed Control System (DCS) on a Greenfield or retrofit wet FGD installation. The “Traditional” installation utilizes dedicated cables to hardwire non-intelligent field devices to input/output (I/O) cards. The Digital Bused Plant (Bused) installation uses bused I/O, high speed field communications networks, and intelligent or “smart” field device technology to simplify construction. Costs were estimated for both implementation approaches in five categories: system selection, engineering, construction, startup, and overheads.

Smart Technology and Its Impact on New Plant Construction

Summary:
The advent of “Smart Technologies” using fully digital instrumentation and Fieldbus networks offers significant opportunity for cost and schedule savings in new plant design, construction, and commissioning, as well as numerous benefits in on-going plant operation and maintenance. A recent study demonstrates the incorporation of these “Smart Technologies” within a new project management approach could save as much as $20 million in procurement, construction, commissioning and start-up costs on a new 600 MW coal-fired unit. To fully realize these benefits it is important to understand these technologies and consider them in a systematic approach from the beginning of the plant development schedule. This paper will provide an overview of the basic technologies. their application, impact on design, area of cost savings, and specific project recommendations that should be considered.
