Company Profile • NG2 is a start up company aiming at the development manufacturing and sales of innovative equipment’s and services aiming at the improvement of vessels and terminals with regard to : • Environmental performance • Economical performance Liquefaction Storage Shipping Storage Regasefication
Company Profile • NG2 company created in July 2008 • Its first development is an ASSU (Argon Separation and Storage Unit) for membrane LNGCs : NG2TANK • Other development’s are identified… • Main offices in Vernon... 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 Heat fluxes throughinsulation box
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 QflexQmaxLNGCs : • Reducedliquefaction plant power consumption • Reduced HFO consumption • Reducedemissions
Examples Dual Fuel Qflex & Qmax
PLUG on board power port PLUG concept “ PLUG ” stands for “PowerGeneration during Loading & Unloading” • « Hands out » design • Operation by a single crew member • Self mating /demating connector • Emergency release capability • Water tight connector
LNGC « Power port » Floats, or aerial supports Connecting towing cable Towing power line Power line active Emergency release PLUG Operations
Power generation isprofitable Cold ironing isprofitable Gains Power generation cost optimisation Reduced emissions On board generation cost On board generation cost On board generation cost
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 … Inside view of an LNGC ballast tank
Gains • Reduced corrosion, reduced silt deposit Reduced ballast tank maintenance, increasedsafety • No transportation of Aquatic Nuisances Species Suppress Gulf water Contamination risks • Use of Renewablefresh water source compared to desalination plants : • Reduced power consumptioncost • Reducedemissions : CO2, ,Brine water…
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…!
