Abstract: A fuel tank arrangement in a liquid hydrogen fuel supply system (1), the fuel tank arrangement comprising: - a tank (10) for storing liquid hydrogen fuel, the tank (10) is formed of an inner tank shell (10a), an outer tank shell (10b) and a heat insulation (10c) therebetween, - an inlet line (11) for supplying fuel to the tank (10), - a liquid outlet line (12b) for supplying liquid fuel from the liquid space of the tank (10), - a gas outlet line (12a) for supplying gaseous fuel from the gas space of the tank (10), - a main gas evaporator (152) connected to the liquid outlet line (12b) for evaporating liquid fuel into gaseous form and supplying gaseous fuel for a consumer (8), - a tank connection space shell (101) together with a part of the outer tank shell (10b) enclosing a tank connection space (100) wherein lead-throughs to the tank (10), inlet line (11) connected thereto, outlet lines (12a, 12b) connected thereto, the main gas evaporator (152) and ventilation lines (102) are located, - the tank connection space shell (101) is formed of an inner shell (101a), an outer shell (101 b) and an inert gas space (101 c) therebetween, an inert gas supply (130) for supplying inert gas is connected to the inert gas space (101c). The invention relates also to a method in monitoring gas-tightness or potential leakages in the fuel tank arrangement.
