1 Offshore Oil and Gas Applications of Undersea Cable Systems Suboptic 2007 Greg Otto - BP w/rob Munier Tyco Telecommunications

2 Topics How is connectivity being used in the Oil & Gas Industry How does fiber fit into the connectivity choices Gulf of Mexico fiber & Other geographies Considerations in planning, engineering and constructing System Ownership Facility Types Topsides Constraints Landings Route Risers Pipeline Crossings Terrestrial and Backhaul Safety Expandability & Reach Logistics Wet Plant Maintenance

3 Expanded Asset Operations Team: Remote Monitoring & Support Ops Mgr Fac Eng Subsea Eng The Right People Vendor in the right place EPTG New Asset Culture: One Virtual Asset Team Right Behaviors Across the Miles The ACE will enable improved decision making and execution through: utilization of real-time data streamlined communication and collaboration shared context between offshore & onshore expanded pool of connected resources

4 Real Time Surveillance - Demo Rotating Equipment Real Time Drilling Drilling Visualization One Touch Topsides Monitoring ISIS Integrated Marine Monitoring Riser/Mooring Data Subsea/Well Surveillance Process Net AWS (Subsea)

5 ACE Environments Onshore Remote Ops Support Replicated Offshore Data (Read-Only) 24/7 Video Conferencing Real-Time Monitoring: Topsides Marine Subsea Drilling

6 GoM - Asset Team Areas Offshore Line of Sight Virtual Team Meetings Dedicated Onshore Team

7 Typical Floor Holstein Horn Mountain Marlin Mad Dog

12 Gulf of Mexico Fiber 2 lit fiber pairs w/32 λ per pair Optical Add/Drop branching units 7 Initial facilities with 12 future BU s One λ per platform 10 gpbs λper Handoff via Gigabit Ethernet in two directions IP re-routing for redundancy Repeaterless branches Subsea repeatered PFE at landings ~1100 kilometers in trunk ~200 kilometers of tails Loop expansion of 300km BUs have 100km reach Wet mate connectors on 4 facilities to enable expansion to sub-tended facilities 3 existing umbilicals / 4 new umbilicals ~60 pipeline crossings

13 Prospective Fiber Opportunities Aberdeen Norway Azerbaijan Gulf of Mexico Egypt Trinidad Indonesia Angola

14 Ownership Models Customer Owned & Operated Consortium Integrated Private networks Companies own discrete segments and Share capacity. Drivers for specific Models Established alternatives not available. Time to access capacity is critical Sole client requirement Many customers with similar demands Timeline is not critical path Many existing working relationships Basins under development Need for a first mover Managed Service Local Telecomms regulations Established providers in basin Measurable demand Have to balance cost versus risk of near term and long term access Models can evolve over time and conditions allow

15 Facility Types Spar Semi-Submersible FPSO Fixed Is a good source of info

16 Turret How to pass a high speed optical circuit across an optical swivel?

17 Topside Constraints Limited topside space 2 racks OLTE Batteries Network Gear Subtended transmission Amplifiers Adequate power AC & DC Steady state Reduced operations Power survivability Generators UPS Subsea tie-backs (No Topsides) Subsea OLTE Subsea distribution Subsea connections

18 Landings Weather: Survivability to extreme weather conditions Security: Can the landing station be secured from physical intrusion Safety: Can the site be accessed in an efficient and safe manner Backhaul: How available, costly and reliable is backhaul capacity Routing: is there an approach free of oil field congestion and environmental concerns Right of Way: Can onshore right of way be obtained efficiently by a private company

19 Route Permits and environmental considerations Good cable engineering and ICPC standards Pipeline crossings: optimize the route length and the quantity Lease Block Crossings: Negotiations with leaseholders Seabed activity and planned developments Manifolds, anchors and mooring lines Growth areas: Where will demand exist in 10 years as new facilities come online and how will that be planned for given lack of fixed/public plans?

20 Riser Design Clashing study Terminations I and J tube dimensions and weigh loading Cable design Simple versus complex cantenary Installation Fusible link Turrets on FPSO s Vortex Induced Vibrations FDC Riser Cable Fusible Li nk I-Tube

21 Pipeline Crossings Pipeline crossing agreements Common engineered solutions include Uraduct and mattressing Methods of procedure may include: Notifications Pre-inspection Bottom and top mattressing Touchdown monitoring PLIB

22 Terrestrial Outside Plant and Backhaul Permitting, easements and rights-of-way Route optimization Trench specification Empty ducts and dark fiber Long term maintenance

23 Safety Stringent HSSE requirements Stringent Management of Change Supplier operations must have comprehensive HSSE programs in strict compliance with Producer programs Supplier programs, factories and vessels will be audited Supplier personnel must meet training requirements for helicopter transfer and offshore operations Use of divers is discouraged due to cost and safety implications ROV s are preferred All diving is hard hat diving no SCUBA Vessels must be DP II to operate within 500 m of a platform

24 Expandability and Reach System upgrades Stubbed branching units Extension of trunk Add bandwidth using OADM technology GigE expansion Auxiliary segments FDCs Router to router Long-reach Spur Tangential Subtending Ring Linear Chain Bisecting Subtended Ring Wirel ess

25 Logistics Platforms have limited bed space or allowances for Personnel on Board (POB). Riser pull ins have to be coordinated with other facility activities and allowances have to be made for alternate/delayed connection processes without significant damage to overall schedule Transportation to and from platforms for both personnel and equipment requires special planning. Platform operator may be in best position to provide and coordinate

26 Wet Plant Maintenance Separate Wet and Dry Plant Maintenance Logistics Integration with other activities Key Decisions Maintenance solution Storage of spares Options for Wet Maintenance Professional marine maintenance provider Modular repair spread Options for Spares Storage Regional depot Local depot Maintenance Authority Services
