Start of the Project

• Review of the existing market and situation 2003
• Statoils contribution
• Einar Wold Svendsens 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

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

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 gt 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

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

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

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.

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.

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.

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

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 contd

• But we have redefined the way to put it together,
  using the simple life as baseline for the
  development
