The Cost and Sustainability Benefits with Integrated Process and Power Automation Architectures in Electro-Intensive Oil and Gas Plants

摘要

Objectives/Scope:The oil and gas plant industry is looking for increased cost and energy savings, particularly with the recent changes in global macroeconomic conditions. In response to this plant automation suppliers have been looking at simpler more collaborative automation architectures. This paper outlines the case for an integrated architecture which enables benefits throughout the entire plant definition, construction, and operative lifecycle, preserving the relevant engineering autonomy for three distinct automation domains, Process Control, Process Safety and Electrical Network Management. Methods, Procedures, Process:Describes the automation landscape and briefly defines the various automation domains, subsystems involved and description of the common interface techniques used on generic system in the upstream oil and gas industry. Describes the emergence of the Electrical Management and Control System based on IEC61850. Reviews newer smarter electrical technology used for efficiency and energy availability gains and its consequent impact on the automation systems designs. Contrasts the techniques used in the shift between static and dynamic load shedding and its relevance to the architecture. Results, Observations, Conclusions:A preferred integrated architecture is described with an outline of practical constraints and objectives. A first order model estimate of engineering effort savings in integration is determined. The evolution of more efficient Electric Power technology and the emergence of a networked EMCS electrical design information model and architecture coupled with a VFD usage provides an increased rationale for the incorporation of dual-language supervision of ICSS and EMCS. The paper concludes that engineering, capex and plant energy efficiency improvements in mechanical and electrical designs can be improved through adoption of the preferred automation architecture. Novel/Additive Information:The paper develops a model based comparison of automation effort on multiple segmented autonomous systems using different networking information models.
