20m³ Single/Double Cold-Box LNG Marine Gas Supply System
The LNG ship fueling system primarily consists of an LNG loading station, LNG storage tanks, and a cryogenic container (which includes heat exchangers, tank pressurizers, buffers, piping systems, control valves, instrumentation, junction boxes, the container body itself, supporting structures, and drip trays, among other components).
The cold boxes in the gas supply systems of LNG vessels can be categorized into single cold boxes and dual cold boxes. Among these, dual cold boxes can feature either a left-right design with two separate heads or a front-to-back configuration with two distinct ends.
