Hydraulic tool

A hydraulic tool for moving a first structural element in an axial direction in relation to a second structural element, wherein the first structural element comprises an annular shoulder which faces an opposite annular shoulder on the second structural element, the hydraulic tool comprising:

• a frame configured to be inserted into a gap between the annular shoulder on the first structural element and the annular shoulder on the second structural element, the frame comprising an upper side and an opposite lower side;
• and
• a plurality of hydraulic power members fixed to and distributed along the frame, the power members configured to exert an axial pushing force against one of the annular shoulders to thereby move the structural elements apart,
• wherein:
• the frame is ring-shaped and further comprises a first arc-shaped section and a second arc-shaped section, each one of the arc-shaped sections comprising a hinged first end and an opposite second end;
• and
• the arc-shaped sections are pivotable in relation to each other between an open position, in which the second end of the first arc-shaped section and the second end of the second arc-shaped section are spaced apart, and a closed position, in which the second end of the first arc-shaped section is in contact with the second end of the second arc-shaped section.
