Moss TM LNG Carriers LNG Carriers The Moss TM LNG carrier with spherical LNG tanks represents the safest and most reliable LNG containment system on the market. The spherical tank offers simplicity in fabrication and operation, and after more than 30 years of operation, the Moss LNG tank design remains unmatched in terms of reliability and unplanned off-hire. The simplicity of the spherical shape of the Moss LNG tank enables high accuracy for predicted stresses and fatigue life of all parts of the tank structure, thereby eliminating the need for a full secondary barrier. Partial loading at any tank filling level is inherent in the design, making both existing and new Moss LNG carriers superior to carriers with other containment designs, especially when handling spot trades and offshore loading/unloading. Moss LNG tanks are independent from the ship s hull and are not to the hull strength nor affected by possible damage to the ship s hull. Propulsion includes: slow-speed diesel engines, steam turbines, duel-fuel diesel electric or combined-cycle turbines, with single or twin screws. Tank volumes 147,000 270,000 m 3 4-5 spherical tanks per LNG carrier Service speed: 19.5 22.0 knots Propulsion: Slow-speed diesel engines, steam turbines, duel-fuel diesel electric or combined-cycle gas turbines, with single or twin screw Moss Reliquefaction System The Moss Reliquefaction System is based on a closed nitrogen expansion cycle that extracts heat from the boil-off gas: All cargo preserved during voyage Partial liquefaction and separation of non-condensable, which means reduced power demand Reduced liquefaction power consumption due to reduced BOR (0.085% - 0.10%/day) 4

Safety and Reliability Moss Containment System Moss LNG Tanks are the industry reference for reliable LNG transportation. They feature: Robust tank structure Unbeaten record over 5000 tank-years with no failures or leaks Design not susceptible to sloshing damage: any filling level is confined in the tanks Design suitable for worldwide harsh environment operations Moss LNG carriers are designed with a considerable average distance between hull skin and cargo tanks. Extensive model tests have verified that a 40m diameter Moss cargo tank may suffer a 4m indent before rupturing LNG Tank Sloshing The shape of Moss LNG tanks is designed to minimize sloshing forces and avoid filling restrictions. Moss LNG tanks are fit for: Large carriers Partial cargoes Floating terminals Offshore shuttling Spot trades Increased Flexibility and Economies Moss LNG tanks ensure: No restrictions on partial filling Maintenance-free cargo tank and insulation system Easy and quick stripping Pressure discharge in case of pump failure Easy visual inspection of the insulation and the inner hull at any time 5
