APPLICANT: HANDELSBOLAGET RODOVERKEN TITLE: METHOD OF ERECTING LARGE CYLINDRICAL STORAGE TANKS WITH A PLURALITY OF VERTICAL PLATE BODIES ARRANGED INSIDE ONE ANOTHER ABSTRACT OF THE DISCLOSURE The present invention relates to a method for constructing a multi-walled large cylindrical storage tank, comprising vertical wall bodies made of plates welded together into a helix form, said plates being added at the lower body ends, successively as the body is moved upwards along the helix until the desired body height has been reached. The novel and characteristic features of the invention are that a plurality of wall or plate bodies are constructed inside one another, starting with the outermost and that an opening is left near the lower end of each finished body, through which opening the plates are inserted into the body under construction immediately inside the last finished body in the form of a tongue comprising at least one plate welded at one end to the plate course under construction, said plate tongue, by displacement of the body along the helix, is pulled in through the opening and is successively welded at its upper edge to the lower edge of the plates in the immediately preceding plate course.
