Gotta have FAITH
October 1st 2009 Petroleos Mexicanos (PEMEX) has
chosen FAITH partial stroke testing
systems from Netherlocks for three
offshore facilities in the Gulf of
Mexico. The FAITH tests ESD
(emergency shut-down) valves with a
partial stroke operation and,
therefore, does not interrupt
production during the test.
The mechanical nature of the
FAITH system ensures that the
specified degree of opening (test
angle) is not exceeded during the test.
The Netherlocks device can also be
used to block the actuator to perform
maintenance on the ESD during
production. Instead of relying on a
potentially complex electronic system
for a simple – but vital – operation,
the FAITH is itself a simple,
maintenance-free mechanical device
that can still offer electronic feedback
with optional added components. More articles from Netherlocks BV: |
