4 1 GTT Overview 4

5 GTT in brief An engineering company with more than 50 years of experience in the design of the Membrane Cargo Containment Systems GTT is a public company listed on the Paris Stock Exchange A core shareholder, Engie (40,1%) and Temasek (10,4%) Independent directors guarantee an autonomous governance of the company More than 100 projects (1) (LNGC, VLEC, FSRU, FLNG, GST and LNG as a fuel ) currently on order Roughly 400 highly qualified people (1) focusing on addressing new market requirements, such as : Low BOR systems (particularly for spot) Intermediate filling levels (particularly for offshore) Small scale LNG Carriers (for retail LNG) LNG as fuel tanks Multigas vessels Large and flexible onshore storage tanks GTT North America subsidiary located at 3 Riverway, Suite 1140, Houston, TX (1) As of September 30 th,

6 GTT remains the reference provider of LNG transport and storage solutions Global leader in LNG containment technologies (85%+ of LNGC orders) With a broad exposure across the LNG shipping and storage value chain E&P Liquefaction Shipping LNG FPSO Onshore storage liquefaction plant LNGC FSRU Regasification Onshore storage regasification terminal Off Take / Consumption 6

7 GTT membrane achievements 1964 First ship delivered with Technigaz LNG tank design 1972 First Membrane onshore tank, still in operation today 1981 First Membrane LNG tank and bigger LNG tank capacity at this time 1996 Largest onshore tank delivered ( m3) 2005 First RV delivered and first LNG operations in open seas 2007 To 2010 Delivery of the largest LNG Carriers (31 Q Flex and 14 Q Max) 2011 GTT is awarded Shell Prelude FLNG cargo tanks 2012 First LNG Carrier sails thru the Arctic North East passage th ship delivered th Ship delivered 2012 GTT is awarded Petronas FLNG1 cargo tanks th ship delivered 7

8 LNG containment systems deployment over the history 1) European Shipyards: From 1964 : Birth of membrane and Moss systems 4) Korean shipyards: Mid 90 s : arrival of membrane and Moss technologies ; quick predominance of membrane 3) Japanese shipyards Moss, membrane development SPB birth 2) American shipyards: End of 70 s : a quick passage stopped by the freeze of LNG development in USA 6) Returning to US & Canada 5) Chinese shipyards Mid 2000 s : membrane only 8

9 First LNG Bunker Barge Contract signed February 25 9

10 Case of 2,200 m 3 LNG Membrane Bunker Barge in US Control Room Cargo Machinery Room REACH4 Bunker Mast Main Parameters: LOA : 64.6 m (212 ft) B: 14.8 m (48.5 ft) D: 4.78 m (15.69) Draft: 2.50 m (8.20 ft) Lightweight: 717 MT Speed: up to 8 knots Engine Room Single Cargo Tank: GTT Mark III Flex CCS Cold LNG Delivery (on-board reliquefaction) No filling restrictions Features GTT patented REACH4 bunker mast AIP received from both ABS and DNV GL Project developed since mid-2013 Mutliple shipyard quotations received Cargo Tank: m3 (100%) 2,156 m3 (98%) Max Cargo 8.1 m3 NBOG per day No liquid level restrictions Power for Operations: On-board diesel generators for simplicity; DF or NG for BOG as fuel; additional BOG management flexibility 10

12 2 Tank technology options and key parameters for safe and cost effective solutions 12

13 Land storage tank options Non Full Integrity storage types Full Integrity storage types (safest designs) Single containment Double containment 9%Ni Full Containment GST Membrane Full Integrity Largest footprint Easiest and fastest to built In case of failure, LNG is contained by a dyke In case of failure, LNG is contained by the secondary wall Membrane tanks and 9%Ni are the safest Membrane tanks offer flexibility Multiple configurations can be envisioned Other benefits are also achievable Evolution of the double Containment In case of failure, both LNG and NG are contained by the concrete walls Above-ground Semi-buried Typical configurations Most compact & economical design In case of failure, both LNG and NG are contained by the concrete walls Inground Cryogenic cavern 13

14 Key parameters to consider cost effective LNG tank construction 1. Develop safest technical solution as per national and province regulation 2. Develop optimize tank sizing 3. Optimize prefabrication and consider technologies favorable for local workmanship 14

15 1.Develop safest technical solution as per national and province regulation Curent LNG Standards in Canada: CSA Z edition BCOGC regulation July 2014 update Main change Inclusion of Membrane Full Integrity tank system as per International Standards 15

16 2. Optimize tank sizing With small diameter or height increase significant volume increase! CAPEX scaling effect apply on LNG tank 16

17 2. Develop storage with limited footprint 3x160,000m³ 9%Ni Full Containment Vs 2x240,000m³ Membrane Full Integrity Total 9%Ni case Total Membrane case Quantity saved Foot print 33,500m² 23,500m² 10,000m² Insulation surface 60,000m² 50,000m² 10,000m² Dead Stock 39,000m³ 29,000m³ 10,000m³ Direct Labor hours 1,400,000h 900,000h 500,000h 17

18 Case study : Typical design for m 3 Either increase the tank net capacity (by 22%) Or reduce land footprint and height visibility 9% Ni Full Containment Membrane Full Integrity 18

19 Evaluate hydrotest exemption Hydrotest is key test for self supported steel structure, but not in Membrane Canadian Standard CSA Z276 allows exemption for hydrotest on Membrane Full Integrity tanks provided : Soil are SA and SB (Hard rock or Rock soil types) Unless required by AHJ Savings: 4 to 6 weeks schedule saving Environmental friendly (No water handling/cleaning issues) 19

20 3 : Encourage Modularization Standard and light components whatever the tank capacity. TIG lap welding, no added filler metal. One welding pass. 85% Auto Complete tank installation modularized and to be installed by local workmanship 20

21 Modular for all sizes, all shapes.. In Pit solutions Above ground Solutions GTT Membrane Gravity Base Structure (GBS) Multi functions storage 21

22 Case of remote LNG infrastructure area Tanks farm Single tank Reduced footprint, cost effective, no risk of BLEVE, limited process piping & more local content! 22

23 Storage capacity (cbm) A segmented product to store LNG for «Canadian made» tank 1K 5 K 10 K 30 K 300 K+ SOT (Small Onshore Tanks) Metallic or concrete envelope, (Full or Single integrity) Cylindrical flat bottom Metallic or concrete envelope, (Full or Single integrity) GST Concrete with polygonal inner face (Full integrity) 23

24 In summary Membrane is a credible & viable option Streamlined & optimized technology, with upside potential Referenced in the latest International Standards Can be easily considered for small & big scale Favorable for local labor Reduced footprint & carbon footprint Cost & schedule savings Generalized through licensed contractors & several Canadian contractors ready to offer Membrane tank installation Make in Canada : Yes, we can! 24
