Systems, methods, and apparatus for desalinating water are provided. A
vessel includes a water intake system, a reverse osmosis system, a
concentrate discharge system, a permeate transfer system, a power source,
and a control system. The concentrate discharge system includes a
plurality of concentrate discharge ports. A water intake system installed
on a sea-going vessel positioned on the surface of a body of water
includes an apparatus for taking up seawater from the body of seawater.
The apparatus includes a water intake member, a water intake positioned
on the water intake member, and an impingement, entrainment, and
entrapment mitigation device at least partially surrounding the water
intake and including a plurality of apertures sized to prevent entry of
marine organisms into the water intake. A method of desalinating water on
a sea-going vessel positioned on the surface of a body of seawater
includes the steps of intaking seawater from the body of seawater into
the vessel through a first screen including a plurality of apertures
sized to prevent entry of marine organisms into the water intake, and
removing salt from the seawater taken into the vessel to yield
desalinated water and a concentrate.
