An object of the present invention is a connection arrangement comprising at least one double-walled pipe of stainless steel and a LNG tank (1) having an inner shell (2) of stainless steel and an outer shell (3) spaced at a distance from the inner shell (2), at least one connection between said at least one double-walled pipe and said LNG tank (1), which comprises said inner and outer shells defining an isolation space (14) therebetween, wherein the at least one double-walled pipe comprises a common outer wall (9) and at least one inner pipe (8), wherein the outer wall (9) of the pipe is connected to the inner shell (2) of the tank by a pipe fitting (10) by arranging the pipe fitting (10) of cold resistant material between the said inner shell (2) and the outer wall (9) to compensate for changes in the length of the outer wall (9) of the pipe and/or for changes in the length of the pipe fitting (10) caused by temperature differences between the outer wall (9) of the pipe and the inner shell (2) of the tank (1). The outer wall (9) of the pipe and a tank room (4) connected to the LNG tank (1) act as a second barrier in case of liquid or compressed gas leakage covering all associated valves and piping. |
