One of the world’s largest refineries reduces costs & improves operational analytics infrastructure by migrating from PI System to dataPARC.
Headquartered in Seoul, South Korea, and a wholly owned subsidiary of Saudi Aramco, S-Oil Corporation is the 3rd largest refinery in South Korea, producing petroleum, petrochemical, and lubricant products for global distribution. S-Oil’s Onsan Refinery in Ulsan has a capacity of over 650k barrels per day.
“One of dataPARC’s advantages is that it can quickly and easily connect to our existing data sources.”
S-Oil had been using OSIsoft’s PI System for process data management since it was introduced in 1997. Over the course of 20+ years S-Oil experienced declining performance with PI as the system struggled to provide quick access to the large amounts of data now stored in the historian. At the same time the need for data to improve decision making was increasing , significantly increasing future costs for the PI System.
In dataPARC, S-Oil found a system that would provide all the functionality of their PI system, unlimited user licenses, improved performance, and upgraded trending and analytics tools. All of this was achieved with a lower total cost of ownership.
The biggest challenge S-Oil believed they faced was in converting and importing 20+ years of data, displays, and reports into dataPARC. Additionally, they had numerous integrations with ancillary systems (LIMS, ERP, etc.) that they would need to re-establish with dataPARC as well.
Migrating to dataPARC
Fortunately, the dataPARC team is quite experienced in leading large-scale PI replacement efforts. After 3 ½ months, the team had completed the following migration:
- 20+ Years of data migrated
- 150,000 Tags
- 100+ PI DataLink Reports
- 400 PI Active View Displays
- 800+ ProcessBook Displays
It was essential that integrations with S-Oil’s critical data sources would survive the migration. dataPARC was able to easily establish those integrations.
Phase II: Upgrading S-Oil’s Analytical & Operations Management Capabilities
Post-migration, S-Oil was eager to begin to leverage dataPARC’s tools to optimize their processes and increase the efficiency of their operations. They moved forward with a number of initiatives supported by the capabilities of their new plant information management system.
to predict process variables
dashboards to optimize consumption
to notify personnel of process deviations
system to improve maintenance
Improved Performance. Reduced Cost.
Immediately, data access speed and reliability in trending long-term data sets was improved remarkably by leveraging dataPARC’s Performance Data Engine. Data queries that used to take several minutes, was now being returned in seconds. In addition, S-Oil was able to greatly reduce operating expenses thanks to dataPARC’s unlimited user license model and reduced maintenance costs.
