The present invention relates to a connection system and a method for connecting and disconnecting a floating unit to and from a buoy which is connected to a subsea installation, where the buoy comprises a first connection device for connecting pipes and/or lines for transfer of fluid, control signals and/or electric power between the buoy and the floating unit. The connection system further comprises a support structure which is laterally movable relative to the floating unit and a swivel stack arrangement movably mounted on the support structure. The swivel stack arrangement comprises a second connection device for connecting to the first connection device in the buoy; shut-off devices for opening and closing at least one of the pipes and/or lines in the first and second connection devices by connecting and disconnecting the buoy; and a turret bearing for rotating the buoy relative to the floating unit.
