Daewoo Shipbuilding and Marine Engineering ("DSME") has developed various LNG carriers of different sizes and propulsion systems to meet the increasing demands for new generation large LNG carriers.

To ensure safety and reliability, particularly for the large LNG carriers, the following core design issues have been intensively investigated:
- Sloshing of large cargo tanks to assess the acceptable number of cargo tanks.
- Structural strength assessment for allowable stress, fatigue and buckling criteria.
- Alternative propulsion systems, such as electric propulsion with dual fuel engine (or gas turbine) and 2-stroke slow speed diesel engine propulsion system with reliquefaction plant. Steam turbine ships are not regarded as suitable for these large LNG carriers due to the limit in available power.
- Optimum hull form development combined with the number of screws.

This paper discusses some of the research and conclusions reached.
