Leverage AI-infused APM to prevent unplanned downtime from shutting down the value chain

SCG Chemicals is one of the largest petrochemical companies in Thailand and a key industry player in Asia. The company's integrated operations include initial production of olefins and subsequent production of polyethylene, polypropylene and polyvinyl chloride.

With its closely integrated business, the company ran the risk that the failure of an individual piece of equipment could shut down the entire production chain with direct implications for financial performance. To address this risk, SCG Chemicals undertook a digital transformation initiative to leverage data to create an advanced asset performance management (APM) solution to monitor critical assets and predict failures toward the goal of zero plant downtime.

The company partnered with AVEVA to develop a digital reliability platform (DRP), a complete asset performance management solution to predict equipment health, monitor performance and enable advanced maintenance to eliminate unnecessary downtime. planned. Using a combination of on-premises and cloud-based applications, the solution integrates online and offline equipment data to visualize plant performance, improve workforce efficiency, and apply artificial intelligence (AI) for predictive maintenance and resolution.
