A multi-use vessel designed to receive a variety of float-on modules that accommodate project specialty equipment and still allow the mother vessel to operate in the traditional construction mode. The vessel may be formed as a new construction or by converting an existing vessel. The vessel is provided with a deck between the gunwales (tween deck) that is lower than the gunwales. The tween deck is provided with docking ports to receive and secure float-on modules containing the equipment required for the desired operation. The tween deck may also be provided with a moon pool for laying pipeline directly through the vessel. The vessel is ballasted to position the tween deck below the water line so that the float-on modules may be installed or removed. The gunwales of the vessel may include one or more cranes spaced along the length of the vessel for moving equipment on the float-on modules or performing installation operations and lifts as necessary. The rear gunwales may include lowering equipment for lowering equipment such as templates to the sea floor. |
