  2. “Contractor shall implement modern technology in . . . . . . . . . . Diving spreads and equipment”

  3. Key Contributors • StatoilHydro • Initiated project as requirement within a 5 year Diving, Pipeline repair, Contingency and Modifications services contract for the Norwegian Continental Shelf. • Sponsoring development of new Personal Diving equipment for use by the commercial offshore diving. • Technip Norway • Managing the project as part of the above contract. • Initial operational implementation will be onboard Technip vessels. • Deep Life • Originator of the Open Revolution concept for design of life critical safety systems (www.deeplife.co.uk). • Main sub-contractor developing the technical solutions based on a dual rebreather core.

  4. Main PDE subsystems TOPSIDE UNIT & DATA SERVER SUPERVISOR SURFACE SUB-SURFACE DIVER’S HELMET BELL UMBILICAL REBREATHER & MUX DIVER’S UMBILICAL DRY SUIT & HEATED UNDERSUIT BELL 4

  5. Applicable Standards and specifications • List of safety requirements and harmonising standards or other specifications systems applied to the system: • Personal Protection Equipment Directive, 89/686/EEC • EN14143:2003, A Harmonised Standard, Rebreathers • EN61508:2004, functional safety of electrical/electronic/programmable electronic safety-related systems • The Restriction of Hazardous Substances Directive (RoHS) 2002/95/EC • The EMC Directive 89/336/EEC • The EMC Directive 2004/108/EC • The Low Voltage Directive (LVD) 2006/95/EC • The Machinery Directive 98/37/EC and Directive 2006/42/EC • NORSOK U-100 1999, Manned Underwater Operations • NORSOK U-101 1999, Diving Respiratory Equipment • NORSOK S-002, Working Environment • NORSOK S-005, Machinery – Working Environment Analysis • DNV-OS-E402 2004, Offshore Standards For Diving Systems • IMCA AODC 035, The Safe Use of Electricity Underwater • OSHA 29 CFR Part 1910 Subpart T: Commercial Diving Operations

  6. Main subsystems – Rebreather - 1 • Rebreather as Primary and Bail-out breathing system • Secondary bail-out using open circuit surface supplied umbilical gas • Dual rebreather core with high safety integrity and reliability of MTBCF > 109 Hours (SIL 4) per core • Gas efficient: • Works as Closed Circuit Rebreather on 100% O2 OR • Works as Semi Closed Rebreather with surface supplied gas or integral bail-out gas (up to 25% O2 )

  7. Main subsystems – Rebreather - 2 • Automated functions: • Onboard bail-out (50 min @ 200m, RMV 62.5 lpm, 200 bar, 2 x 2 ltr in Semi-closed mode) • Surface supplied open circuit bail-out • System start up and diagnostics • Loop ppO2 control • Monitoring and logging of all critical parameters for divers in real time on-line • Autonomous on loss of umbilical • Uses dual Micropore 5” scrubber cartridges: • Very low Work of Breathing • High endurance • No dusting • No channelling • Very low risk of caustic cocktail • Quick change

  8. Main subsystems – Rebreather - 3 • Comprehensive monitoring of system parameters: • ppO2 • ppCO2 • ppHe • pp Hydrocarbons & CO • Pressure (depth) • Relative Humidity • Flood • Loop Temperature, Ambient Temperature • Divers Tidal Volume • Divers Breathing Rate • Scrubber Health (temperature profile) • Scrubber Life (CO2 consumed) • Scrubber fitted (sensor and visual) • Supply gas pressure • Bail-out gas pressure • Battery Life

  9. Main subsystems – Rebreather – 4 • Gas Manifold • Surface supplied umbilical gas • O2 connection • Gas from left and right bail-out cylinder • Gas supply to left and right rebreathers • Gas supply to helmet • Helmet Stab Plate – single composite connection for all services • Breathing loop • Helmet gas supply • HDTV quality cameras (2) • Lighting (2, up to 150W each) • Communications • Diver alarm • Peripheral Field Device (PFD) – LED • Rebreather voice alarm annunciation

  10. Main subsystems – MUX • MUX (Multiplexer) integral to rebreather digitizes all signals and provides power and alarms: • Multiple redundant data paths • 2 x optical fibre • 2 x copper pairs (only one path of one type required) • Digital communications (24 bit) & Video • Control of lighting and video • Diver alarm • Helmet integrity alarm • Control of diver heating system • Rebreather counterlungs • ECT Under suit (4 zones) • Rebreather power • MUX is dual redundant, and has no software to go wrong

  11. Main subsystems – Topside • Topside System to: • Communicate all data to and from rebreather • Monitoring, logging and alarming of all critical parameters for divers in real time on-line. Available for immediate action and long term analysis • High reliability server for data • storage and Supervisor interface • management (via web browser) • Stand alone system for fitting to current • DSV’s • Open data format for integrating into • future DSV’s or current software

  12. Main subsystems – Dry Suit, Helmet, Umbilical • Dry Suit • Keep the diver dry and protected against contamination and thermal effects of the environment (HDS). • Active heating using Electric Conductive Textiles (ECT). • Passive thermal protection in the event of loss of heating. • Helmet • Smaller/lighter – less stress on diver. • Active monitoring of latch mechanisms. • Diver “emergency” alarm. • Heated visor (active de-mist). • Semi-Customised fit. • Umbilical • Single moulded composite of Ø 26 mm • O2 and surface/bell supplied gas • Quad redundancy on power and communications

  13. Ergonomics Comfort and Reduction in Complexity • Improve the divers mobility and vision • The equipment shall be lighter easier to handle and more comfortable to wear • Improved gas efficiency • Reduce umbilical size • Clear digital communication to topside • Camera for overview and "portable” camera for Inspection. • Compact, tough, reliable adjustable lights • Reduce Complexity • Rebreather on the diver. No reclaim system. • Electrical diver heating - No diver hot water machinery. • Low and simple maintenance with long service intervals. • Self diagnostic.

  14. Interface with existing equipment Simple and easy interface - The system does not require a major refit Additional Bell umbilical leads for transmittal of digital signals Can be refitted through using the return hose in existing umbilicals Need a new optical slip-ring, but simpler due to less gas and water transfer Dive Control Simplifications Simplification of the bells Simplification of slip rings With the system, Reduced Hot Water Minimised corrosion problems Significant operating energy savings With the system, lower maintenance cost 14
