The hull has an opening therein for positioning under a moon pool of a drill ship. The barge hull further includes a support structure for contacting a bottom of a hull of a drill ship when the drill ship is positioned over the barge hull. The barge has a mooring system having capacity to either hold the barge in position or hold both the barge and the drill ship when the drill ship is fully supported by the barge out of the water over a wellbore location.
