Operational Experience
Operational Experience - Corrective Sequence
Observation
High variations in both
suction pressure and pump
power consumption
Action
Recommended the
Customer to open the
recirculation choke
27
Operational Experience
Operational Experience - Corrective Sequence
Observation
A drop in barrier pressure
during a flowline pressure
test caused negative seal
dP towards process
Action
Called the Operators, and
recommended bleeding off
the flowline pressure
28
Operational Experience
Operational Experience - Corrective Sequence
Observation
Diverging temperature
readings from two
neighbouring transmitters,
which if left unattended will
reach HH and trip the
pump in 2-3 months
Action
