ABB and Dresser Masoneilan will collaborate on an integrated process to monitor, test and manage emergency shutdown valves during all operational conditions, from normal to abnormal plant operations.

These emergency shutdown valves (ESDV) are crucial process elements for the oil, gas and petrochemical industries, as well as many other industrial processes.

The combined solution leverages the capabilities of ABB’s 800xA high-integrity safety instrumented system (SIS) and Masoneilan SVI II emergency shutdown device (ESD) 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 also simplifies safety compliance by automatically recording partial stroke test results and emergency shutdown events, saving time and money while increasing efficiency.

Kristia Olsson, manager of ABB’s Safety Center of Excellence, said: ‘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 ESDV.

‘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.

‘This immediate readiness is vital to the protection of the process, the environment, and the surrounding community in the event of an abnormal situation,’ Olsson added.

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 said to provide a good return on investment with its combined shutdown function, partial stroke test function and shutdown event ‘black box’ in a single SIL3-certified device.

It is the latest technology in emergency shutdown valve automation and in-service valve partial stroke testing.

The SVI II ESD is said to be 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 are an LCD display and explosion-proof external pushbuttons.

This design architecture offers a sophisticated platform while being Type A (simplex device) compliant.
