25. Operational Experience

26. Operational Experience Operational Experience • Excellent relationship with client, OneSubsea always updated. • Planned maintenance/upgrade of equipment done in minimum time. • Reduced operating and maintenance costs. • Optimal use of the equipment (configuration).

27. Operational Experience - Corrective Sequence Operational Experience Observation High variations in both suction pressure and pump power consumption Action Recommended the Customer to open the recirculation choke

28. Operational Experience - Corrective Sequence Operational Experience 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

29. Operational Experience - Corrective Sequence Operational Experience Observation Diverging temperature readings from two neighbouring transmitters, which if left unattended will reach HH and trip the pump in 2-3 months Action Inform Customer & Agree on Solutions
