Abstract
(EN)
The present invention relates to a fuel tank arrangement of a marine vessel, the tank arrangement (12) comprising a liquid hydrogen fuel tank (20), a tank connection space (30) arranged in communication with the liquid hydrogen fuel tank (20), the tank connection space (30) being provided with a vent mast (40) having a lower end and an upper end, and an interior, the interior of the vent mast (40) forming a ventilation outlet line (62) for discharging gas from the tank connection space (30), an emergency pressure relief valve (34) coupled via a safety valve line (36) to the gas space (38) of the fuel tank (20), wherein a first hydrogen outlet line (92) provided in the vent mast (40) is separate from the ventilation outlet line (64), the first hydrogen outlet line (92) extending from the lower end of the vent mast (40) to the upper end thereof and being arranged in flow communication with the emergency pressure relief valve (34).
