The compressed natural gas (CNG) emerging as new gas technologies - CNG carriers
Transporting The Compressed Natural Gas (CNG):
Compressed Natural Gas (CNG) has been developed as a shipping concept, relying on the
high pressure containment technology used in conventional pressure vessel CNG storage and in
pipeline systems to provide a form of concentrated gas storage which can be fitted onboard ships.
The CNG concept that has been around for a long time, seeks to offer savings by removing the
need for the expensive onshore refrigeration trains required for LNG. However, CNG still needs
separate gas conditioning and process systems to get the production gas segregated and suitable
for transportation. A separate LPG processing and transportation system is also needed.
Although gas demand is growing, a simple development approach, with appropriately lower
CAPEX and OPEX, is required to serve the smaller or “stranded” reserves. Hence, there has
been a re-emergence of CNG proposals.
Processing is still required to condition the natural gas
for shipment as CNG. Condensates, NGL’s and water are removed from the product before it is
able to be compressed for storage in marine transportation containers. Like LNG, the LPG’s are
processed and shipped separately.
