Abstract

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.

First claim

The invention claimed is:

1. An apparatus for fluidly coupling to a free-floating body, the apparatus comprising:
a conduit having a first end and a second end, the second end opposite the first end, and the second end for coupling to a floating storage vessel;
a conduit assembly coupled to the first end of the conduit, the conduit assembly comprising a plurality of nozzles for releasing one or more fluid streams to direct the conduit assembly to or from a receiving port of the free-floating body; and
an internal passage for fluidly coupling the floating storage vessel to the receiving port of the free-floating body, the internal passage along the conduit and extending through the conduit assembly.

2. The apparatus of claim 1 , wherein the plurality of nozzles comprises a first set of nozzles oriented to propel the conduit assembly along a first direction, a second set of nozzles oriented to propel the conduit assembly along a second direction opposite the first direction, and a third set of nozzles oriented to propel the conduit assembly along a third direction orthogonal to the first direction and the second direction.

3. The apparatus of claim 1 , wherein one or more of the plurality of nozzles is configured to be actuated to control a corresponding one of the one or more fluid streams.

4. The apparatus of claim 1 , wherein the internal passage comprises a first internal fluid passage, and a second internal fluid passage co-axial around the first internal fluid passage.

5. The apparatus of claim 4 , wherein the first internal fluid passage is configured to supply an energy product precursor from the floating storage vessel to the receiving port of the free-floating body, and wherein the second internal fluid passage is configured to siphon an energy product from the receiving port of the free-floating body to the floating storage vessel.

6. The apparatus of claim 5 , wherein the energy product precursor is deionized water, and wherein the energy product is hydrogen gas.

7. The apparatus of claim 4 , wherein the internal passage further comprises a third internal fluid passage co-axially surrounding the first internal fluid passage and the second internal fluid passage, the third internal fluid passage configured to supply a fluid to the plurality of nozzles.

8. The apparatus of claim 1 , further comprising:
an intermediate lifting assembly interposed along the conduit between the first end and the second end of the conduit.

9. The apparatus of claim 8 , wherein the intermediate lifting assembly is configured to expel one or more auxiliary fluid streams to support suspension of the conduit within a surrounding environment.

10. The apparatus of claim 1 , further comprising:
an intermediate pump assembly interposed along the conduit between the first end and the second end of the conduit, the intermediate pump assembly configured to pump a fluid to the plurality of nozzles.

11. An apparatus, comprising:
a conduit and a conduit assembly, the conduit assembly positioned at a distal end of the conduit, the conduit assembly configured to semi-autonomously or autonomously mechanically couple a first free-floating body to a second free-floating body, wherein the conduit assembly includes one or more fluid nozzles configured to expel one or more fluid streams which are timed and angled so as to guide the conduit assembly to a receiving port of the second free-floating body so as to mechanically and fluidly couple the conduit assembly to the receiving port.
