(八)About aspenONE for Petroleum

     aspenONE for Petroleum is an integrated, comprehensive set of software solutions, professional services, and partnerships designed to help the downstream petroleum industry achieve operational excellence.

      By using aspenONE for Petroleum in the plant, petroleum companies can enhance safety and reliability, improve throughput and product yields, reduce energy costs, improve crude acquisition and selection processes, make more profitable
refinery plans and schedule process units and blends more effectively. It also provides solutions for the real-time performance
management of the refinery.

      aspenONE for Petroleum also allows petroleum companies to integrate the refinery with the supply chain, enabling integrated plant operations with optimal distribution planning, improved trading margins, real-time inventory visibility with reduced risk exposure and optimal positions, reduced supply shocks such as stock-outs and demurrage, and lower overall distribution costs in both primary and secondary distribution.

      Based on AspenTech's Aspen Operations Manager integration infrastructure,aspenONE for Petroleum provides the key capabilities refiners and petrochemical manufacturers need for real-time performance management:

• A unified view of manufacturing and supply chain information and KPIs
• An ability to synchronize manufacturing plans with supply chain processes based on accurate insight into plant capabilities
• An ability to detect and respond to unanticipated manufacturing and supply chain problems and opportunities
• An ability to monitor and analyze operational KPIs, perform root cause analysis and leverage models to facilitate optimal decision making

      Its combination of applications and services addresses challenges associated with the five major business areas of the petroleum industry:

• Engineering & Innovation. Improvement of plant performance through such techniques as benchmarking analysis and continuous process enhancements.
• Plant Operations. Safe and reliable plant operation with minimal energy costs and improvements in yields and throughput; an ability to meet the demands of activities such as refinery planning, scheduling and blending.
• Regional Planning. Development of operating plans,taking into consideration multiple periods, plants, commodities, markets, and transportation modes across a given geographical region.
• Supply, Distribution & Trading. Optimization,scheduling and managing "front line" decision making and operational execution.
• Fuels Marketing. Achieve fully automated and optimized supply chain management in secondary petroleum and petrochemical distribution.
