Integrated solution for monitoring, testing and management of emergency shutdown valves

14 October 2010

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

The combined solution is said to utilise 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 overall plant safety and increase the availability of ESDVs for optimal response of the isolation valve in emergency situations. This integration is also said to simplify safety compliance by automatically recording partial stroke test results and emergency shutdown events, saving time and money while increasing efficiency.

“By taking advantage of System 800xA’s 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,“ said Kristian Olsson, manager of ABB’s Safety Center of Excellence. ”This immediate readiness is vital to the protection of the process, the environment, and the surrounding community in the event of an abnormal situation.”

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 minimises the need for outages and downtime to evaluate the health and readiness of these critical process elements. This also provides easy to understand alerts and recommendations regarding valve status, as well as required partial stroke test and emergency shutdown signatures and documentation.

The SVI II ESD is the latest technology in emergency shutdown valve automation and in-service valve partial stroke testing. The SVI II ESD is the only SIL3-certified ESD certified at 4mA with stainless steel housing. The device can be implemented using a 4/20mA signal (analogue safety demand), 0-24Vdc (discrete safety demand) or a combination of both. Standard on the device is an LCD display and explosion-proof external pushbuttons. This design architecture offers a sophisticated platform while being Type A (simplex device) compliant. System 800xA High Integrity is ABB’s next generation safety system. This SIL 3 rated Safety Instrumented System (SIS) provides the highest level of integration of safety and control on the market today, and a unique embedded diverse technology architecture that provides superior protection of the process, plant, personnel, and the environment while it optimises overall process efficiency.
