Abstract: The invention relates to a valve system of a fuel tank, especially of an LNG tank, which valve system includes at least two pressure relief safety valves, in which valve system one pressure relief safety valve is located in one safety valve branch branching from an outlet line from the LNG tank. The valve system further comprises interconnected shutoff valves for shutting off one of the safety valve branches at time and that the shutoff valves are diverter valves with a T-bore.

Abstract: A cryogenic tank arrangement includes a tank body enclosing a storage space for storing liquefied gas. The tank arrangement has a safety valve arrangement in which at least one pressure relief valve is directly connected to the storage space of the tank body. There is a pressure relief valve arranged directly connected to at least two locations on a same face of the tank body.
