6 Siemens Subsea offer solutions for key challenges Today Key technology challenges Future! Greater water depths (over 3000m)! Remote locations! Extended wellstream tiebacks 2) (up to 500km) Topside Subsea 95% 5% 1! Providing electrical power (up to 36 kv)! Highest level of reliability and process safety Topside Subsea 5% 95% 2 Topside! Processing equipment! Power transmission equipment! Personnel for operation and maintenance! Topside facility (incl. maintenance) = HIGH CAPEX and OPEX Power Grid is the enabler of subsea production Step-out distance [km] Artic sea Snovhit Asgard Subsea! Processing equipment! Power transmission and distribution equipment! No personnel for operation and maintenance! No topside facility needed! Optimized reliability (up to 15yrs MTBF 1) ) = OPTIMIZED CAPEX and OPEX Siemens takes on the challenge and will provide the Subsea Power Grid to enable remote subsea production 1) MTBF; Mean Time Between Failure 2) Step-out distance between production well and processing facility Source: NCE Subsea, E O ST BD Slide 6

7 A seafloor power grid is required to increase the productivity of subsea wells Strong subsea growth Need for subsea processing Subsea wells underperforming # of new subsea well ( ) Forecasted # of power consuming units Compression Separation ESP +70% % oil recovery 70% recovery gap compared to best practice surface wells Boosting Pumps Need for large scale subsea boosting and processing to increase recovery and thus a reliable Seafloor Power Grid Source: Quest, Infield, NPD

8 Why Developing Subsea Power Grid? Subsea power distribution is the key enabler for future power consuming subsea processing Subsea power is key enabler for subsea processing Enabling technologies (Relative importance) Power (MVA) Subsea power distribution technologies Standard Long distance Very long distance DC Transmission Oil co s main focus AC Transmission kv Enabling technologies identified by operators as the ones required to make subsea processing widespread Getting reliable, field proven power distribution systems considered to be the most important enabler Distance, km AC is the key focus area today, while DC by most are put off for the next 3-5 years Technology risks are viewed to be manageable, and oil co s do not see any real show stoppers

12 Subsea power and distribution is a natural entry point for Siemens Siemens - the worlds electricians are committed to delivering the power behind Subsea Processing Slide 12

13 The Siemens Subsea Power Grid Today = a subsea power consumer like pump and compressor is powered directly from a topside installed variable speed drive ( VSD) through an umbilical. Future = If we have more consumers, larger power and /or longer step outs a subsea power distribution is required km Slide 13

21 Direct Electrical Heating installed at several Statoil fields, however DEH is still an immature technology Installed fields! Statoil and BP is a user of this technology! Selected DEH systems installations: - Åsgard (2000) - Huldra - Kristin - Norne - Tyrihans - Alve - Morvin - Skarv Projects in Execution! DEH contract for Skuld, awarded to Siemens in June 2011! Siemens has delivery experience from several fields! Siemens will start studies for electrical heating of long flow lines>200km for two oil companies in 2013 Slide 21

22 Siemens Subsea Control! The key system parts are a Topside Control Unit (TCU) which acts as a transparent communication link between an operator and one or more subsea control units (SCU). The SCU s connect to the new upgraded instrumentation and controls by jumpers.! The Subsea control unit can provide a variety of services to inform the operator as to the condition of subsea wells, and even control them. It can connect to:! Cameras! Sand detectors! Multiphase meters! Hydrocarbon leak detectors! Pressure and temperature sensors! Electrical actuators! Directional control valves! The system works independently of the original control system so it can be used on systems irrespective of the vendor. Slide 22
