Fuel Gas Supply System for LNG MEGI & DFDE Engine of LNG Propulsion Vessel
CRYOS FGSS for Low/High Pressure
Design and Calculation
| System | Application | Load Case Combination |
|---|---|---|
| Type-C Tank | Inner Tank-Outer Tank Saddle | Static (Design pressure + Fluid weight) |
| Static (LNG weight + Vacuum pressure) | ||
| Asymmetric load (Rolling, Pitching) | ||
| Dynamic (0.5G + 1.0G) | ||
| Thermal analysis | ||
| Low / High Pressure FGSS |
Vaporizer | Strength analysis (Skid, Support, Cold box) |
| HP / LP Pump | Thermal analysis | |
| Glycol Skid | Pipe stress analysis | |
| Insulation Piping | Explosion analysis |
| System | Fuel gas Pressure | LNG tank pressure | Energy Efficiency | Engine |
|---|---|---|---|---|
| Low Pressure FGS | 10 barg | 4~15 barg | Low | DFDG |
| 15 barg | High | RT-FLEX | ||
| High Pressure | 300 barg | High | ME-GI |
