Integrating emergency shutdown valves with process control system

ABB and Dresser Masoneilan integrate capabilities to improve overall process safety, emergency valve performance, and availability.

10/13/2010


ABB’s power and automation technology group, announced that it will collaborate with Dresser Masoneilan, a supplier of process control valves, on 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.

“Our collaboration with industry leaders like Dresser Masoneilan helps us offer our mutual customers best-in-class safety solutions that will protect the integrity of their processes and the surrounding community,” said Luis Duran, ABB’s Americas business development manager for safety systems.

He adds that 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 overall plant safety and increase the availability of ESDV’s for optimal response of the isolation valve in emergency situations. This integration also simplifies 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 shutdown 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 minimizes the need for outages and downtime to evaluate the health and readiness of these critical process elements. The system also provides alerts and recommendations regarding valve status, as well as required partial stroke test and emergency shutdown signatures and documentation.

“While open standards offer great benefit for end users, it is the collaboration between automation vendors that provides for an ‘out-of-the-box’ solution capable of generating instant results,” said Sandro Esposito, global marketing manager digital products for Dresser Masoneilan.  “The SVI II ESD provides an excellent return on investment with its combined shutdown function, partial stroke test function and shutdown event black box into a single SIL3 certified device.”

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