A gas supply marine vessel and a floating refueling facility are described. The gas supply marine vessel includes a hull with an upper deck having an elongated cargo cavity formed therein. Gas interface modules are disposed in the cavity and extend between hull sides, each module having a plurality of fuel vessel docking stations. A plurality of stacked fuel container assemblies are fluidically coupled to the docking stations. A gantry, movable along the length of the cavity, straddles the cargo cavity between hull sides. An articulating crane is mounted on the gantry and it utilized to move fuel container assemblies to a fuel container depression formed in the deck of the floating refueling facility. The floating refueling facility may include a concave side to facilitate mooring adjacent a shoreline, the concave side forming angled extensions at corners of the deck with a linkspan extending from each of the angled extensions.

A lifting system includes elevator towers constructed on a deck of a floating vessel, tracks constructed above the deck of the floating vessel, a traveling cradle beam, and one or more cranes supported by the traveling cradle beam. The traveling cradle beam can be in a first configuration in which the traveling cradle beam is coupled to the elevator towers and can move along the elevator towers past the tracks, and in a second configuration in which the traveling cradle beam is decoupled from the elevator towers and can skid over the tracks. The lifting system can be constructed in stages, and the portion of the lifting system constructed in the initial stages can be used to continue constructing the lifting system in the remaining stages. The lifting system can be used for transporting equipment on the floating vessel.

Devices and methods for recovering an unmanned underwater vehicle. The device includes a gantry mounted on a recovery vehicle, a frame, and a shaft extending between the gantry and the frame and configured to vertically move the frame relative to the gantry. Attached to the frame are a plurality of rotatable arms movable between an opened position and a closed position. A first end of each arm is attached to the frame at a pivot. A flexible strap extends between each of the second ends of the arm and the frame. As the arms are moved to the closed position around the unmanned underwater vehicle, the straps will support the unmanned underwater vehicle.
