Operational Experience - Corrective Sequence

Operational Experience

ObservationHigh variations in both suction pressure and pump power consumption

ActionRecommended the Customer to open the recirculation choke

28

Operational Experience - Corrective Sequence

Operational Experience

ObservationA drop in barrier pressure during a flowline pressure test caused negative seal dP towards process

ActionCalled the Operators, and recommended bleeding off the flowline pressure
