1 Yamal LNG Carrier Development 2 nd March, 2017 DSME

2 History of Cooperation between DSME and First co-operation agreement between Daewoo Shipbuilding & Marine Engineering and Technology was signed and entered 16 Th of April First years co-operation projects: Ice going LNG carrier for Baltic sea 100k class Arctic Aframax-tanker 2008 two pod propulsion system Hull form optimization for Arctic Aframax Tanker (2009) Third co-operation period is on-going and will be continued up to 2020.

3 Cooperation for Arctic Design Technical design development for Arctic LNG carrier concept has been started on 2010 within DSME-AAT cooperation framework. Long term cooperation for Arctic Technology DSME Design development Performance Evaluation Design consulting Ice model tests Classifications Design review Approval Model manufacturing Open sea model tests Design review

4 History of LNGC Design Development in DSME Year 2010: 90,000m 3 Shuttle LNGC - Murmansk to Yamal peninsula - Arc 7 class, twin POD propulsion - Economic evaluation with three bow design alternatives - Hull form development and model tests Year 2011: 170,000m 3 LNGC - Arc 7 class, hybrid propulsion (twin POD with conventional propeller) - Study for different propulsion concept - Bow type study incl. bulbous bow - Hull form design and model tests Year 2013: 172,600m 3 LNGC (aft contract for Yamal LNGC) - Arc 7 class with 3 POD propulsion - Hull form optimization for open sea and Ice operation - Performance confirmation through model tests

5 Economic Evaluation on Type of Bow in Russian Arctic Area (90k Shuttle LNGC, Year 2010) Extreme ice bow is suitable for shuttle service in Arctic area (5~6% larger cargo volume is expected) Trading routes Moderate Bulbous Study with Total delivered cargo in a year Bulbous Moderate Extreme

6 Technical Evaluation on Type of Propulsion System (90k Shuttle LNGC, Year 2010) DFDE with podded drives is suitable for shuttle service in Arctic Study with Machinery alternatives Response ice loads Power flexibility Fuel consumption Fuel flexibility Emission, SOx Layout flexibility Weight of all machinery Investment cost Steam turbine Slow speed diesel with CPP Geared medium speed with CPP DFDE with shaftlines DFDE with podded drives : Excellent, 4: Good, 3: Medium, 2: Tolerable, 1: Poor

7 Principal dimensions study Ice performance as function of beam, Turning capability of different propulsion concepts Ice performance as function of bow form, direction 7

8 Design basis for Yamal Arctic LNGC Source: Novatek

9 Double Acting Operation and Concept of Hull form optimization BOW Optimized for open water performance Increment of ship speed Ship turning point STERN Optimized for ice capabilities Increment of ice thickness

10 Bow type study bulbous bow[f1] Extreme Ice bow[f2] Stern [A1] (2 PODs+center propelle

11 Stern form study Aft body (ice capability improvements) The stern form will create a icecrack to correct position so that no big unbroken ice floe will hit to the strut of the side azipod and that the created ice floes are small enough to go through the "tunnel" between the CL pod and side pod.

12 Hull form optimization Concept BOW : Extreme ice bow Moderate ice bow for better open sea operation STERN : Shape optimization for ice interaction for better ice operation
