An OpreX Asset Operations and Optimisation solution that improves plant systems interoperability and security through support of the OPC UA communication standard.

June 2, 2021 – Yokogawa Electric Corporation has announced that Yokogawa and Shell have jointly developed Platform for Advanced Control and Estimation R5.03 and will release it on June 2 as a solution under the OpreXTM Asset Operations and Optimisation family.

Platform for Advanced Control and Estimation is a software suite that brings together Shell's advanced plant process control technology and Yokogawa's real-time control technology to help customers improve productivity by increasing product yield and reducing energy consumption. This version upgrade supports Open Platform Communications Unified Architecture (OPC UA), the latest version of a communication standard that improves plant systems interoperability and security and provides the basis for digital transformation to help customers transition to industrial autonomy.

Advanced process control (APC) systems improve product yield and reduce energy consumption by maintaining temperature, flow rate, pressure, and other process values within a set range and keeping them as close as possible to their optimal set points. Such systems are increasingly used in facilities such as oil refineries, petrochemical plants, chemical plants, and LNG trains.

Yokogawa's Platform for Advanced Control and Estimation suite delivers the following functionalities:

• Multivariable model predictive control (the control of multiple variables based on predictions made using models of the dynamic characteristics of plant responses)

• Soft sensing for estimating quality in real-time based on temperature, flow rate, pressure, and other process values

• Customisation of calculations

Yokogawa has continued to enhance this suite in response to changing customer requirements. The release of version R5.03 meets urgent industry needs for enhanced plant systems interoperability and security.
