The invention relates to a liquefied gas outlet system (100) for liquefied gas tank to discharge liquefied gas from below its surface level in the tank (10), the outlet system comprising a first conduit section (102) attached by its outer periphery at a location of a opening (104) arranged to a wall section (24) of the tank serving as an liquefied gas outlet, at least one second conduit section arranged in flow connection with the first conduit section (102), via which at least one second conduit section (106,106') the first conduit section may be arranged in flow communication with the tank inner volume (30). The system further comprises a safety vessel (110) arranged to circumscribe the opening (104) in a secured manner inside the tank, and that the safety vessel is also secured to the at least one second conduit (106, 106'), and that the second conduit section is provided with a closing unit (108,108'). Invention relates also to a tank for storing liquefied gas having a liquefied gas outlet system, as well as to a method of building or rebuilding a liquefied gas tank. |
