Embodiments disclosed herein include a vessel for floating and traveling adjacent to an upper surface of a body of water. In an embodiment, the vessel comprises a support structure, a first floatation chamber coupled to the support structure, a second floatation chamber coupled to the support structure, the second floatation chamber laterally spaced apart from and fluidly coupled to the first floatation chamber, and a third floatation chamber coupled to the support structure, the third floatation chamber laterally spaced apart from the first floatation chamber and from the second floatation chamber. In an embodiment, the vessel further comprises a robot system coupled to the support structure, where the robot system comprises an end effector and a nozzle head coupled to the end effector.

A system for charging electric vehicles on or near water includes a charging station and a shore station. The charging station comprises an aquatic structure which can be attached and/or moored to a shore and/or the ground/bed of the body of water, and receptacles that are assembled around the aquatic structure and connected to it. The receptacles are preferably all water-proof, and collectively house various components for allowing the recharging of an electric vehicle. The shore station is remote and mechanically disconnected from the charging station. The shore station is at least partially, if not entirely, above water and attached to the shore of the body of water, for example to a quayside. The shore station includes communication means that complement the communication means of the charging station.

A floating LNG storage barge with one or more LNG tanks provides mobile storage for LNG, by obtaining LNG from one or more LNG ocean transport vessels while the LNG storage barge is moored to a land-based jetty, transferring LNG to one or more land transfer trucks, pipelines or railroad tankers using an LNG distribution manifold and flexible hoses between the distribution manifold and the trucks via pumps or pressure differential between the LNG storage barge with the potential for LNG processing adaptive capacity.

Methods and systems are provided for transient fluidic coupling via reversibly couplable conduits. In one example, a method includes directing a conduit assembly to a receiving port by releasing one or more fluid streams from the conduit assembly. The method may further include fluidly coupling an internal passage of the conduit assembly to the receiving port. The internal passage may extend from the conduit assembly and along a conduit between a pair of free-floating bodies, such as between a wave engine and a tanker ship, so as to exchange one or more fluids, such as an electrolysis reactant and an electrolysis product. The fluidic coupling may be reversible, in that the conduit assembly may be detached from the receiving port to sever the fluidic coupling. In certain examples, the detaching may be actuated by releasing one or more additional fluid streams from the conduit assembly.

Some embodiments relate to a storage system for liquefied natural gas (LNG). An example storage system for LNG comprises: a floatable vessel formed as a barge, the vessel including: a vessel frame, a hull around the vessel frame and defining fore and aft sections, and a deck supported by the vessel frame; at least two LNG storage tanks carried by the vessel frame. A first LNG storage tank may be positioned on a port side of the vessel and a second LNG storage tank may be positioned on a starboard side of the vessel. Fluid transport conduits connected to the at least two LNG storage tanks to allow fluid flow into and out of the at least two LNG storage tanks may be provided. A valve system to control flow of fluid in the fluid transport conduits may be provided. The vessel frame and the hull may define a broad and shallow draught.

A system for charging electric vehicles on or near water includes a charging station and a shore station. The charging station comprises an aquatic structure which can be attached and/or moored to a shore and/or the ground/bed of the body of water, and receptacles that are assembled around the aquatic structure and connected to it. The receptacles are preferably all water-proof, and collectively house various components for allowing the recharging of an electric vehicle. The shore station is remote and mechanically disconnected from the charging station. The shore station is at least partially, if not entirely, above water and attached to the shore of the body of water, for example to a quayside. The shore station includes communication means that complement the communication means of the charging station.

A mobile energy harvesting device and method for using the same are described. In one embodiment, the device comprises a hull with a steering system, wherein the steering system steers the device. The device also includes a sail coupled to the hull and configured to propel the mobile energy harvesting device. An energy storage device is coupled to the hull and is configured to store energy. The device also further includes one or more energy generation devices configured to produce energy to be stored in the energy storage device. A control system is positioned in the hull and includes a control center communicatively coupled to a sensor, wherein the sensor detects input and communicates the input to the control center and the control center communicates with the steering system to steer the mobile energy harvesting device.
