35 SPRINGS development & qualification Conceptual Design Qualification Step 1 1. Conceptual studies Membrane hyperbaric tests Qualification Step 2 Subsea Test Unit (STU) 3. Design 4. Qualification 5. Manufacture 6. Offshore tests Congo

36 Qualification step 1: Membrane lab tests Membrane integrity and performances tests Laboratory tests with hyperbaric chamber Subsea conditions applied: Pressure: 300 bar(g) Temperature: 4 C Successfully completed in October 2011 Membrane performance within acceptable parameters Membrane integrity confirmed on completion 17

37 Qualification step 2: Offshore in-situ tests In-situ offshore tests required 1st qualification of the whole process Measure membrane fouling rate Validate operating & IMR philosophies Subsea Test Unit solution Deep offshore tests Representative process Reduced scale Tuning design for each specific site 18

38 Qualification step 2: STU design Subsea Test Unit Design by Saipem Sonsub Mechanical design comparable to a ROV 19

39 Qualification step 2: STU Qualification STU component endurance tests Throughout 2012 and 2013 Validate endurance of main components against: wear internal corrosion Components tested: brushless electric motors seawater pumps on/off valves flow control valves pilot solenoid valves biocide injection system Cumulative running hours: >2000 hrs 20

40 Qualification step 2: STU Manufacturing Subsea Test Unit manufacturing March March 2014 Work performed by Saipem Sonsub in Marghera (Italy) 21

41 Qualification step 2: STU Offshore tests LARS 10 tons 22

42 Qualification step 2: STU Offshore tests STU Offshore hook-up & commissioning Installation / Commissioning Offshore Congo May/June

43 STU Operation Operation Commenced: 12 June 2014 Completed: 18 October 2014 Satisfactory performance Product water sulfates content Key equipment function without issue Membrane fouling Rate of TMP and DP increase observed Intervention frequency forecast from fouling rate Nature of fouling established by autopsy 24

44 Post-Operation Testing Membrane autopsies Quantify level of membrane fouling Investigate nature of membrane fouling 25

45 Conclusions SPRINGS STU allows optimization of: process design, IMR strategy, feed water inlet location STU ready for testing at other sites: Up to 3000 meters SPRINGS design validated by offshore tests SPRINGS economical interest confirmed Industrialization phase is on-going 26
