1. A method of providing potable water, comprising:
- extracting sea water from a depth in excess of 400 meters below the sea surface;
and desalinating the extracted sea water;
wherein extracting the sea water comprises;
lowering a submersible pump connected to the end of a flexible extraction riser to a depth in excess of 400 meters below the sea surface; and
using the submersed pump to pump sea water onto a vessel;
said flexible extraction riser acting as both a transport medium for the sea water being extracted and as a load bearing component for supporting the submersible pump and said flexible extraction riser being able to be stored flat when not filled with water.

4. A system for providing potable water, comprising:
-
a ship vessel; a desalination plant mounted aboard the ship vessel; a pump configured to pump sea water from a depth in excess of 400 meters below the sea surface for desalination in the desalination plant; wherein the pump is a submersible pump configured to be lowered to a depth in excess of 400 meters below the sea surface to pump the sea water onto the vessel for desalination in the desalination plant; and a flexible extraction riser attached at one end to the ship vessel and at the other end to the pump, said flexible extraction riser adapted to act as both a transport medium for the sea water being pumped and as a load bearing component for supporting the pump when lowered, said flexible extraction riser being able to be stored flat when not filled with water. - View Dependent Claims (5, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19)

20. A system for providing potable water, the system being adapted for being mounted on a vessel and comprising:
-
a desalination plant; a pump configured to pump sea water from a depth in excess of 400 meters below the sea surface for desalination in the desalination plant, wherein the pump is a submersible pump configured to be lowered to a depth in excess of 400 meters below the sea surface to pump the sea water onto the vessel for desalination in the desalination plant; and a flexible extraction riser for transferring the sea water from the pump to the vessel wherein the flexible extraction riser is adapted to act as both a transport medium for the sea water being pumped and as a load bearing component for supporting the pump when lowered, said flexible extraction riser being able to be stored flat when not filled with water. - View Dependent Claims (21, 22, 23, 24, 25, 26, 27, 28, 29, 30)
