The invention relates to a sealed tank wall for forming a sealed tank for storing a fluid, the wall comprising: - a plane frame (3) comprising a periphery (4) and longitudinal stiffeners (5) placed inside from the periphery (4) in a longitudinal direction so that each longitudinal stiffener extends from one side of the periphery (4) to an opposite side of the periphery (4), the periphery (4) and the longitudinal stiffeners (5 ) being configured to define openings in the frame (3), - lobed walls fixed to the frame (3) by welding around said openings to close said openings, so as to project in a thickness direction orthogonal to the frame ( 3) and towards the outside of the tank to be formed.
