Barge

Any one of many types of flat-decked, shallow draft vessels, usually towed by a boat. A complete drilling rig may be assembled on a drilling barge, which usually is submersible; that is, it has a submersible hull or base that is flooded at the drilling site. Drilling equipment and crew quarters are mounted on a superstructure above the water level.
