  4. Offshore need to follow the lead of the recreational industry Start of the Project • Review of the existing market and situation 2003 • Statoil’s contribution • Einar Wold Svendsen’s initiative • Where are the rest of the industry • Review of the market for rebreathers • Great Opportunities using the “Technical Diving” approach • Success factors initially • 1/2 “ umbilical • I hour full bail-out time for both gas and temperature • Efficient barriers between personnel and environment • Easy to interface with existing equipment Header and Footer (View)

  5. Reason for the Project • Technip awarded the Statoil Diving Framework Contract in 2005 • Enthusiasm regarding goals • The PDE development was funded by the Contract • Definition of rebreather capabilities • Definition of overall approach • Definition of final partners in the development • Problem areas • EU standards for PPE • Monitoring systems using rebreathers • Active vs. passive breathing system • NORSOK U-101 • Norwegian Industry Track-record related to such developments • Success factors presently • 1“ umbilical • 30 minutes full bail-out time for gas and extended thermal comfort • Efficient barriers between personnel and environment • Easy interface with existing equipment Header and Footer (View)

  6. Status per today • Technip / Statoil PDE Development • Goals obtained for Rebreather • The PDE consists of following components • Passive Rebreather developed with a “reclaim efficiency” of > 95% • Electronically managed to EN 61508 standard for SIL4 • State-of-the-future monitoring and communication system • MUX connection to surface with all electronic read-out • Goals obtained umbilical • Single composite umbilical with 1” diameter • Gas, oxygen, fibre optics and twisted pairs • Functions as Safety line with 350 kg. SWL • Goals obtained suit • Actively heated Dry Suit • Viking Suit • Actively heated undersuit controlled through the rebreather MUX Header and Footer (View)

  7. Thanks • Technip / Statoil PDE Development • Good Cooperation within the Project from Statoil & Partners • Roar Joergensen as Contract Representative • Yngve B. Bergfloedt in Technical Follow-Up • Einar W. Svendsen as “Godfather” • Cato Hordnes and Hans Joergen Maeland from Norsk Hydro • Outstanding Partner in overall Development is Deep Life Ltd • Dr. Alex Deas in his role as Primus Motor in all Technical Solutions • Valuable Partner in the Suit Development is Trelleborg AB • Mr. Martin Lundstroem in his quest for a new and stronger suit material, and the interface with heated underwear • Technip’s Project Management • Mr. John Nortcliffe whose technical astuteness and insights defined the success of the project • Mr. Stein Olberg who have manhandled the economy to a successful conclusion Header and Footer (View)

  9. What is in it – for ME • Cost efficiency • The system removes equipment • With the system, no need for diver reclaim • Simplification of the bell • Simplification of dive control • With the system, smaller umbilicals • Simplification of the bells • Simplification of slip rings • With the system, Reduced Hot Water • Minimized corrosion problems • With the system, lower maintenance cost Header and Footer (View)

  10. Interface with existing equipment • Simplicity and easy interface • The system do not require 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 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 • Minimized corrosion problems • With the system, lower maintenance cost Header and Footer (View)

  11. Definitions for new equipment • The New equipment is designed for simple interface with existing systems • Removal of equipment • Simplifications of equipment • Minor needs for changes in the immediate run. • The New Equipment is designed to ease the stress on the Diving Supervisor • No gas handling for divers • All monitoring automated • Good communication • Free time for running the dive rather than the monitoring • The equipment is designed to ease the non-work stress on the diver • Ample survival time in case of emergency • Ergonomically designed systems for comfort • Safety Level same as for being passenger in a plane.

  13. III Twice as much for half the price 1 Savings • CAPEX • No reclaim, smaller umbilicals, no gas to dive control, simplified comms and monitoring. • Reduced or No hotwater, less corrosion, less water problems, removal of size umbilicals, simplified slip-rings. • Standardisation of bell lay-out • OPEX • Less maintenance on technical equipment, simplified bells, optimisation of emergency equipment, smaller umbilicals, removal of all hot water systems, removal of all return gas systems, simplified gas distribution. • Simplified gas inventory, minimised gas reservior dependent on SCR or CCR option.

  14. III Twice as much for half the price 2 Upside / Downside • Upside of Development. • Step Change in the safety of operations due to better ergonomy, better protection against seabed hazards, better monitoring, better communication, better thermic balance, better microbiological balance, better survival abilities. • Downside of the development • New approach to diving, retraining for how to balance yourself in the water, possible overheating, irritation of leaking suit, possible problems with body fluids release.

  15. III Twice as much for half the price 3 Evaluation In general, we believe in it! Because of the potential for improvement And personnel involved so far like it

  16. IV Back to the future • Rebreather are not new, we have used them for ages • Military • Recreational • Bells • Reclaims • Dry Suits are not new • Used inshore • Used in sports diving • Used as protective equipment in chemical environments • Active heating is not new • Hot water suits • Electrolungs • Recreational equipment

  17. IV Back to the future cont’d • But we have redefined the way to put it together, using the simple life as baseline for the development
