 They may be capable of handling LNG tankers of 70,000 to 217,000 cubic metres (m3) cargo capacity (QFlex); or tankers of 125,000 to 266,000 m3 cargo capacity (QMax).The pier would have at least two insulated lines, one for loading and/or unloading LNG and one for vapor supply or recovery as the vapor space above the LNG changes as the cargo is transferred.Ship-based or shore-based cryogenic pumps are used to transfer the LNG to/from the LNG storage tanks on shore.
