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.
