Abstract: A gaseous fuel feeding system having a fuel supply line enclosed by a barrier wall system such that the fuel supply line includes a primary flow channel for the fuel and a secondary flow channel around the primary flow channel inside the barrier wall system, and a valve having a first fluid passage and a second fluid passage arranged to extend through the valve. The valve is coupled between the first and the second fuel supply line sections, such that the primary flow channel in the first fuel supply line section is in controllable flow connection with the primary flow channel in the second fuel supply line section via the first fluid passage of the valve. The secondary flow channel is in continuous flow connection with the secondary flow channel in the second fuel supply line section via the second fluid passage of the valve.

Abstract: A marine vessel includes at least one gas fuel consumer is arranged at a first horizontal level in the vessel, and at least one gas tank for the gas fuel consumer is arranged at a second horizontal level in the vessel, which second horizontal level is different from the first horizontal level. The vessel is provided with a fluid passing shaft for providing a confined vertically extending shaft between a gas consumer at a first horizontal level in the vessel and at least one gas fuel tank arranged at a second horizontal level in the vessel.

Abstract: 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.
