FIELD: transport.

SUBSTANCE: invention relates to marine natural gas production, gas loading and unloading. Liquefied-gas carrier (LNC) with loading and unloading system is available in three versions. In compliance with first version, liquefied-gas carrier is designed to load and unload LNC and comprises system of submerged revolving loading, plant to liquefy natural gas fed via submerged revolving loading to cryogenic liquefied natural gas, at least, one self-supported storage tank mounted on carrier and arranged to allow LNC to be loaded and unloaded via said self-supported storage tank, and, at least, one membrane-type storage tank arranged nearby the first one. Besides, there is, regasifying plant for natural gas stored in self-supported storage tank. In compliance with second version, liquefied-gas carrier is intended for loading LNC and comprises first pipeline to feed LNC to self-supported storage tank and second pipeline to feed LNC from the latter into membrane-type storage tank. In compliance with third version, liquefied-gas carrier is intended for LNC unloading and comprises first pipeline arranged between regasifying plant and self-supported storage tank to unload LNC, and second pipeline to feed, in unloading, LNC from membrane-type storage tank to self-supported storage tank being unloaded.

EFFECT: reduced vibration of fluid on tank surface in loading and unloading.
