在網(wǎng)上查到LNG運(yùn)輸船，天然氣是必須液化才能在港口運(yùn)出來嗎？？是沒有CNG直接運(yùn)出來的嗎？？？求大神指點(diǎn)一二，十分感謝！！

Compressed natural gas (CNG) carrier ships are designed for transportation of natural gas under high pressure.[1] CNG carrier technology relies on high pressure, typically over 250 bar (2900 psi), to increase the density of the gas, but it is still 2.4 times less than that of LNG (426 kg/m3).[2] CNG carriers may find their place abreast with the well established technology of liquefied natural gas by LNG carriers as it is economical for medium distance marine transport.[3][4] Most of the energy consumed for the gas pressurisation can be recovered as electricity using turboexpander while delivering CNG to the inland piping network at unloading jetty/harbour. CNG carriers are also alternate solutions to the undersea pipelines as they have less complicated fast loading and unloading features.[3][5]

萬分感謝！��！您是否知道CNG運(yùn)輸船和LNG運(yùn)輸船在短距離海上運(yùn)輸船哪個(gè)更為常用呢？？
