1. An offshore cooling system comprising: a floating vessel comprising a fluid conveyance apparatus comprising a pipe, a pump, and a feedback system, wherein the fluid conveyance apparatus is operable to deploy and retract the pipe and the pump to and from an extraction depth below the ocean surface
1. An offshore cooling system comprising: a floating vessel comprising a fluid conveyance apparatus comprising a pipe, a pump, and a feedback system, wherein the fluid conveyance apparatus is operable to deploy and retract the pipe and the pump to and from an extraction depth below the ocean surface, wherein the extraction depth is at least 100 meters, wherein the pipe and pump are operatively connected and together operable to extract water from the extraction depth, and wherein the feedback system is operable to measure at least two measurements selected from the group consisting of biomass amount, sunlight amount, nutrient amount, and temperature at the extraction depth; anda receiving device comprising a transfer pipe operable to receive the extracted sea water from the fluid conveyance apparatus and transfer the extracted sea water for use as cooling water in a preexisting offshore operation. 2. The system of claim 1, wherein the fluid conveyance apparatus further comprises a winch operable to deploy and retrieve the pipe and pump to variable depths within 100 meters to 1000 meters. 3. The system of claim 1, wherein the pump is a submersible pump disposed at a submerged end of the pipe. 4. The system of claim 1, wherein the preexisting offshore operation is separate from the floating vessel. 5. The system of claim 1, wherein the extraction depth is at least 500 meters. 6. The system of claim 1, further comprising a cooling water heat exchanger system. 7. The system of claim 2, wherein the extraction depth is variable between 100 meters to 1000 meters based on the measured ocean biology productivity and temperature. 8. An offshore cooling system comprising: a floating vessel at a first offshore location comprising a fluid conveyance apparatus operable to retractably extend to an extraction depth below the ocean surface, wherein the fluid conveyance apparatus comprises a pipe, a pump, and a feedback system operable to measure (i) at least one measurement of ocean biology productivity selected from the group consisting of biomass amount, sunlight amount, and nutrient amount and (ii) temperature, wherein the pipe and pump are operatively connected and together operable to extract sea water from the ocean at the extraction depth, wherein the extraction depth is from 100 meters to 1000 meters, and wherein the extraction depth is variable based on the (i) measured ocean biology productivity and (ii) temperature;a cooling water heat exchanger; anda transfer pipe operable to transport the extracted sea water to a second offshore destination, wherein the second offshore destination receives the extracted sea water and uses the extracted sea water as cooling water. 9. The system of claim 8, wherein the extraction depth is at least 250 meters below the ocean surface. 10. The system of claim 8, wherein the second offshore destination is an offshore oil rig. 11. A method for obtaining cooling water for use in offshore operations comprising: providing an extraction system comprising a flexible pipe having a first end and a second end, wherein the first end is operatively connected to an offshore platform, wherein the second end is extendable to at least 100 meters into the ocean and comprises a feedback system operable to measure (i) at least one measurement of ocean biology productivity selected from the group consisting of biomass amount, sunlight amount, and nutrient amount and (ii) temperature, and wherein a submersible pump is operatively connected to the second end;extending the extraction system to a plurality of extraction depths between 100 meters and 1000 meters;measuring the (i) at least one measurement of ocean biology productivity and (ii) temperature at each of the plurality of extraction depths;selecting one of the plurality of extraction depths based on the measured ocean biology productivity and temperature; andpumping extracted water from the selected extraction depth to the offshore platform. 12. The method of claim 11, further comprising feeding the extracted water through a cooling water heat exchanger. 13. The method of claim 11, wherein the offshore platform is located at a first offshore location. 14. The method of claim 13, further comprising the step of transferring the extracted water to a second offshore location, wherein the second offshore location is operable to receive and use the extracted water as cooling water.
