Abstract: A hydraulic tool for moving a first structural element in the axial direction in relation to a second structural element. The tool comprises a ring-shaped frame configured for insertion into a gap between an annular shoulder on the first structural element and an annular shoulder on the second structural element; and hydraulic power members fixed to and distributed along said frame, the power members being configured to exert an axial pushing force against one of said annular shoulders to thereby move said structural elements apart. The frame comprises first and second arc-shaped sections, each of which having a hinged first end and an opposite second end. The arc-shaped sections are pivotable between an open position, in which their second ends are spaced apart, and a closed position, in which their second ends are in contact with each other.
