5 Design Concept of SAYAENDO Key Technologies Continuous tank cover oss/stretched tank UST/Reheat turbine Improved Operating Economy Increased cargo capacity (+8000m 3 from 147km 3 ) FOC saving by UST, improved hull form and less wind resistance. Low BOR (0.15 to less 0.10%/d selectable) Flexibility of fuel selection (100% Gas, 100% Oil & Dual burning) aintenance cost saving(less supporting structure of pipes) Cost Saving Less Steel Weight Better Terminal Compatibility Tradable cargo tank capacity for worldwide terminals Compact dimension on per with conventional 147km 3 LNGC 49m Breadth for New Panama Canal Transit Environmentally Friendly Less CO2 emission by low FOC 100% Gas burning & 100%GO(0.1% sulfur oil)can be used Low NOx Emission (Lower than Tier III level) 2018 ITSUBISHI SHIPBUILDING CO., LTD.

Reduction of Longitudinal Wind Resistance Wind load

is decreased by abt.20-40% from conventional type.

7 Reduction of Longitudinal Wind Resistance Wind load analysis by wind tunnel tests Longitudinal Wind Force is decreased by abt.20-40% from conventional type. Conventional Type It shall contribute to improve fuel consumption in actual voyage. 3-4% improvement of fuel consumption is expected under Beaufort 5 wind scale condition. SAYAENDO Type Lateral wind resistance is increased slightly. Influence on ships maneuverability and mooring at terminals have been confirmed ITSUBISHI SHIPBUILDING CO., LTD. All Rights Reserved. 7
