Disclosed is a swivel stack which can be provided in a turret of a floating structure. The swivel stack according to an embodiment of the present invention comprises: multiple swivels which are stacked in a vertical direction; connection members which are extended in a vertical direction and are connected to the outer side of two or more swivels among the swivels; and a torque arm of which one side is connected to the floating structure and the other side is connected to the connection members. When the floating structure is rotated around the turret, the outer sides of the swivels connected by the connection members are rotated together with the floating structure. Therefore, the present invention simplifies the structure of the swivel stack and reduces material costs.
