Chemical collection and processing vessel and methods for fluid transfer at sea

A method of forming an energy product, the method comprising:

• coupling a vessel to a wave energy conversion (WEC) device adjacent to an upper surface of a body of water, the vessel comprising 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, 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, the coupling comprising positioning the WEC within a footprint defined by the first floatation chamber, the second floatation chamber, and the third floatation chamber;
• transferring hydrogen from the WEC to the vessel;
• and
• while the vessel is floating on the body of water, converting the hydrogen into the energy product on the vessel.
