A liquefied gas fuel feeding system can include a liquefied gas container configured to store liquefied gas and gaseous gas in cryogenic circumstances, a first fuel passage opening into an ullage space of the gas, a second fuel passage opening into a bottom section of the gas and provided with a controllable pump, at least two fuel delivery passages each configured to convey gas to a single gas consumer of at least two gas consumers, and a valve assembly configured to connect alternatively the first fuel passage or the second fuel passage to each one of the at least two fuel delivery passages.

The disclosure relates to a gas valve unit having an enclosure provided with an inlet and an outlet, with an inner pipe arranged to extend from the inlet to the outlet via the enclosure forming a gas tight piping inside the enclosure, and an outer pipe arranged to open into the enclosure via an at least one opening. Walls of the inner pipe and the outer pipe form a space there between as a first volume, and the enclosure forms a space inside as a second volume, the first and second volumes being arrangeable in flow communication with each other via an opening in connection with the outer pipe. At least one blocking unit selectively blocks the at least one opening in connection with the outer pipe and the flow communication between the first volume and the second volume.
