Company Profile

• NG2 is a start up company aiming at the
  development manufacturing and sales of innovative
  equipments and services aiming at the
  improvement of vessels and terminals with regard
  to
• Environmental performance
• Economical performance

Company Profile

• NG2 company created in July 2008
• Its first development is an ASSU (Argon
  Separation and Storage Unit) for membrane LNGCs
  NG2TANK
• Other developments are identified
• Main offices in Vernon...

Argon insulation concept

• Argon thermal conduction 30 lower than nitrogen
  
• 10 Improvement of Thermal performance of NO
  type insulation confirmed by analysis and tests
• ASSU to be developped to
• Reduce OPEX
• Avoid argon logistics concerns

Gains

• For Steam or DF/ DE LNGCs
• Lower nominal speed when using BOG as fuel
• Reduced flaring when operating at low speed
• Increased LNG unloaded cargo
• Reduced emissions

• For Qflex Qmax LNGCs
• Reduced liquefaction plant power consumption
• Reduced HFO consumption
• Reduced emissions

Examples
Dual Fuel
Qflex Qmax

PLUG concept
PLUG stands for Power Generation during
Loading Unloading

•  Hands out  design
• Operation by a single crew member
• Self mating /demating connector
• Emergency release capability
• Water tight connector

Gains

• Power generation cost optimisation
• Reduced emissions

Fresh water ballast concept

• Ballast capacity is 1/3rd of cargo capacity
• A significant share of the LNG route are towards
  countries with large ressources of fresh waters
• Qatar fresh water needs are huge

Gains

• Reduced corrosion, reduced silt deposit

• No transportation of Aquatic Nuisances Species

• Use of Renewable fresh water source compared to
  desalination plants

Examples

Possible Strategy for Qatar LNG

• Argon filled insulation sure winner , to be
  implemented on all vessels
• PLUG and Fresh water ballasting gains and
  feasibility will depend on
• LNG routes,
• CO2 emissions value

Conclusion

• Significant improvements are possible
• but we need to open our mind for cooperation
  with other actors and even industries
• In many cases, environmental gains may generate
  extra profits

• Thank you for your attention!
