The invention relates to a tank ( 11 ) for storage of cryogenic fluids. The tank ( 11 ) comprises a base section ( 12 ), a vertical wall element ( 14 ) and preferably an upper top ( 19 ). The tank ( 11 ) is provided with a fluid tight barrier ( 26 ) intended to prevent the stored fluids to escape to the surroundings. The fluid tight barrier ( 26 ) is formed of thin metal plates joined together. At least the vertical wall ( 14 ) comprises an inner structurally supporting wall element ( 24 ) and an outer structurally supporting wall element ( 25 ). The fluid tight barrier ( 26 ) is arranged between the inner ( 24 ) and the outer ( 25 ) structurally supporting wall element. The invention relates also to a method for constructing such tank ( 11 ), where the base part ( 12 ) is firstly erected whereupon a vertical wall ( 14 ) is concreted, preferably by means of slipforming or jumpforming. Firstly, the inner structurally supporting wall element ( 24 ) of the wall ( 14 ) is reinforced and concreted, whereupon a fluid tight barrier ( 26 ) is arranged on the external side of the inner structurally supporting wall element ( 24 ), whereupon the outer structurally supporting wall element ( 25 ) is reinforced and concreted. |
