CNGC’s upstream sector of LNG procurement and transportation is divided into two modes:

The first mode is importing LNG by ISO containers before the construction of LNG receiving terminal is completed and put into operation. An ISO container is a standard 40-foot tank container; the volume of each ISO container is capable of loading 16-17 tons of LNG. The process is as follows: ISO containers are purchased by CNGC, at first they are filled with LNG at oversea receiving terminal, then they are imported into Cambodia by ocean shipping or overland transportation, at last they are stored in CNGC's Koh Kong multi-function station. CNGC provides full ISO containers or cylinders of LNG to users based on their consumption.

The second mode is that after the LNG receiving terminal is completed and put into operation, CNGC will sign long-term LNG sale and purchase agreements with major LNG producing countries; LNG will be transported by LNG carriers to CNGC’s Koh Kong LNG loadoff jetty in the Bay of Kompong Som, then stored in 180,000m3 storage tanks at the receiving terminal. After the regasification process, LNG is vaporized to natural gas, and natural gas will be transported to Phnom Penh through the main long-distance pipeline. In addition, there are also filling facilities in the receiving terminal to fill LNG into tank trucks; tank trucks will transfer LNG to cities and provinces across the country, implementing nationwide natural gas supply in Cambodia.
