Exchanging Control System Data Securely

The need to share process data between production sites, refinery, petrochemical, gas and utility plants has been increasing for the past decade. These plants and production sites are typically located in the same area and have the need to exchange feed stocks, naphtha, ethane and utilities streams such as hydrogen, electricity, water, steam, and fuel gas, which created the requirement to exchange data between their metering and control systems.

With the tight network security policies of the different companies in the chemical, oil & gas and utility industries, it has become significantly challenging to integrate with third party systems. Integration Objects has designed an OPC UA based solution to enable such integration while complying with the ISA 99 network security standards and the different stakeholders’ policies. Such systems have already been deployed successfully to integrate refinery, utility, oil & gas stabilization, and LNG plants.
