Collaborating on ESDV integration

ABB is to collaborate with Dresser Masoneilan on an integrated process to monitor, test and manage emergency shutdown valves (ESDV) during conditions ranging from normal plant operations to abnormal situations. These valves are crucial process elements for the oil, gas and petrochemical industries, as well as other industrial processes.

The combined solution leverages the capabilities of ABB's 800xA High Integrity SIS (Safety Instrumented System) and Masoneilan's SVI II ESD (emergency shutdown device) and PST Controller to improve plant safety and increase the availability of ESDVs for optimal response of the isolation valve in an emergency. This integration also simplifies safety compliance by automatically recording partial stroke test results and emergency shutdown events.

Kristia Olsson, manager of ABB's Safety Center of Excellence, comments: "By taking advantage of System 800xA's unique integration capabilities and open standards, the user has immediate access to the health diagnostics and status of the emergency shut down valve. This access also provides proactive management of this critical device, for instance enabling remote triggering of partial stroke tests, to ensure that it is ready to perform when needed." As an integrated object within System 800xA,Masoneilan's SVI II ESD device can be configured to perform scheduled partial valve stroke tests while remotely monitoring and maintaining the emergency shutdown valves during normal plant operations. This reduces the need for downtime to evaluate the health of these critical elements.
