CNG Solution for Offshore Gas Transportation

CNG Solution for Offshore Gas Transportation A fleet of ships can deliver natural gas by use of compressed-natural-gas (CNG) technology. These ships can serve as both storage and transport vehicles, discharging directly into a land-based gas-utility grid through an onshore or offshore discharge terminal, an offshore platform, or offshore buoy. A new type of ship uses a large number of vertical pipes, designed according to enhanced-pipeline-design principles, to transport the CNG. The weight of the containment system is 50% of that required for conventional pressure-vessel ship-design codes. The result is a possible large storage volume.
