1 Performance THROUGH H LEADERSHIP E 11 th June 2008 Subsea Asia 2008 Experiences in executing the World s first All Electric Tree Project

2 Experiences in executing the World s first All Electric Tree Project Subsea Challenges or why do we need All Electric systems Introduction to CameronDC Executing K5F for TOTAL E&P Netherlands Summary

3 SUBSEA CHALLENGES Deeper Further Better Added value Environment

4 SUBSEA CHALLENGES MAJOR SHORTCOMINGS Current Technology COST Large Umbilicals Complex Equipment Control Fluid Management GREATEST SHORTCOMING RELIABILITY Complex System DEPENDENCE Moving Parts / Seals EFFICIENCY Response Time / Start-up Inadequate Condition Monitoring LIMITED Step Out Constraints Deepwater Functionality ON HYDRAULICS

5 CameronDC Surface Control System Power Transmission, Communication Electric Actuation Subsea Control Module

6 CameronDC Gate Valve Actuators Used with Standard Subsea Gate Valve Electrically opened, with Low power to hold open Failsafe close using standard Spring Return Redundant Direct position indication actuator stem) Gate Valve Fail-Close Spring Module Gearing and Clutches Electric Motors

7 CameronDC Choke Actuator Used with standard Subsea Insert Choke Electrically functioned; Infinitely adjustable (no stepping ) Fail as is design Redundant Direct position indication (@ actuator t stem) < 2 minute from full open to full close (variable) continuous operation (flow control) Electric Actuator Standard Insert Choke Electric Motors Roller Bearing and Spindle Pinion / Ring Gears (Self Locking)

CameronDC SUBSEA S CONTROLO Electric Subsea Control

8 CameronDC SUBSEA S CONTROLO Electric Subsea Control Module (ESCM) Power Communication Distribution Actuator Control Unit. Motor control Unit Interface module for third party sensors. Power Regulation and Communication Module (PRCM) Communication module. Power Regulator for converting transmission voltage to actuation voltage.

to the required level PRCM will provide the required power to the escm and will command Valve to open Once

9 CameronDC How does it work over long distances? Power Topside unit supplies 3kV DC to each subsea PRCM On demand (Actuator open) the current will be increased to the required level PRCM will provide the required power to the escm and will command Valve to open Once Actuator is open - power is only needed to hold it open ( Watts) Topside Unit will reduce the current via Power Management Software Topside 640 km Subsea end 3 kv Seawater Return

CameronDC How does it work over long distances? Signal System is designed to use subsea LAN protocol TCP/IP Shore to Subsea via Fiber Optic with Repeaters min.

10 CameronDC How does it work over long distances? Signal System is designed to use subsea LAN protocol TCP/IP Shore to Subsea via Fiber Optic with Repeaters min. 100 Mbit/s Seabed communication is high speed DSL min. 192 kbit/s on twisted pair or fiber optic Remote manageable switches subsea All applicable units are selectable via IP address Topside 640 km < 15 km Subsea end FO w/ Repeater Highspeed DSL Template U SUT Template T Template P

11 CameronDC Redundancy Concept Rig Power EPCU A MCS EPCU B Rig Power Anode Umbilical Anode Umbilical Anode Umbilical Anode Seawater Return Cathode PRCM A PRCM B Seawater Return Cathode escm A escm B A A A Act 1 Act 2 Sensor B B B Currently Maximum 16 Functions, this includes Sensor readbacks

12 CameronDC Environment & Safety Environment Zero discharge policy means no fluid discharge Closed return needs extra line Short Times for Start-up and ESD Safety No pressure system No gas bottle handling No precharging No accumulators

13 K5F Project Scope: 2-off Mudline Style X-Mas Trees Production Control System Installation & Workover Control system (rental)

14 K5F Project System Application, Challenges Bring Product from R&D into Industrial Environment Know-how transfer Lock-in Vendors and develop Repeatability escm Product Qualification and Project Execution in Parallel Assembly in a step by step approach Focus on Long Lead items first Management of Change PRCM

15 K5F Project FIT/SIT Set-up 2-off X-Mas Trees Topside Controls Distribution, incl. 5 Km Umb. Redundant Seawater tank w/ PRCMs, Anodes and Cathodes IWOCS

16 FIT/SIT Set-up K5F Project PRCM Cathode 2-off EPCU s MCS Anode Seawater Tank E-Actuator escm Coax Cable X-Mas Tree, top view 2-off 5 Km Umbilical

17 K5F Project System Application, Installation EPCU s installed on TOTAL s K6 Platform Operation of Tree during Well Test, using the DC-IWOCS System First X-mas Tree being installed on K5F2

18 Summary Conclusions or why TM DC power mandatory Truly environmental friendly High Reliability and Availability through Design & Concept Redundancy Network concept Umbilical/Fluid Savings Efficient System Startup ESD execution time

19 TM All Electric. All Cameron. Thank you Questions?
