Cooling coastal waters

Abstract

Methods and apparatus for transporting cool water from the deep regions of the oceans to the shallow waters of the shoreline by a network of, for example, onsite manufactured FRP (Fiber Reinforced Polymer) pipes and pumps. This water displacement lowers the temperature of the shallow water region to a desired level. To implement this method, a long pipe is laid over the seabed, extending from the shallow regions to a desired depth of the ocean where the water is cooler and cleaner than the shallow waters. A mechanical and/or an electrical water pump is then attached to either end of the pipe. The water pump, preferably energized by the water surface waves, will constantly pump the cooler and cleaner water from the depth of the ocean to the shallow waters, reducing the temperature and contamination of shallow waters.

What is claimed is: 
     
         1 . A method of transporting water from a deep part of a large body of water to a shallow part of the large body of water, the method comprising:
 submerging a long pipe in the large body of water from the shallow water parts to the deep water parts;   connecting at least a water-pump to the pipe at a desired location along the length of the pipe; and   pulling or pushing the water through the pipe from the deep part of the large body of water to the shallow part of the large body of water by the water-pump.   
     
     
         2 . The method of  claim 1 , wherein the long pipe is laid over the bottom of the large body of water. 
     
     
         3 . The method of  claim 1 , wherein the pump is operated by wave energy. 
     
     
         4 . The method of  claim 1 , wherein the pump is mechanical, electrical or electromechanical. 
     
     
         5 . The method of  claim 1 , wherein the energy for operating the water-pump is not supplied from surrounding land. 
     
     
         6 . The method of  claim 1 , wherein the pipe is made of FRP products. 
     
     
         7 . A method of protecting bleaching of coral reefs due to increase in temperature of shallow waters, the method comprising pumping cold water from cold water regions into shallow waters to decrease the temperature of the shallow waters. 
     
     
         8 . The method of  claim 7 , wherein a long pipe is laid from the shallow waters to the cold waters in order to transport water from cold water regions into shallow waters. 
     
     
         9 . The method of  claim 7 , wherein a pump pushes or pulls the cold water from the cold water region to the shallow waters. 
     
     
         10 . The method of  claim 9 , wherein the pump is mechanical, electrical or electromechanical. 
     
     
         11 . The method of  claim 7 , wherein the pipe is made of FRP products. 
     
     
         12 . The method of  claim 7 , wherein energy for operating the pump is not supplied from surrounding land. 
     
     
         13 . A method of transporting water from a first location to a second location, the method comprising: pulling or pushing the water through a pipe laid between the first and the second locations wherein the pipe is manufactured onsite by helically wrapping a strap of resin-impregnated fabric around a cantilevered mandrel and continuously offloading the wrapped pipe from the open end of the mandrel at a same rate as the pipe is formed on the mandrel. 
     
     
         14 . The method of  claim 13 , wherein the energy for the pulling or pushing the water is obtained from water waves. 
     
     
         15 . The method of  claim 13 , wherein the pipe is laid over the bottom of the large body of water. 
     
     
         16 . The method of  claim 13 , wherein the pulling or pushing of the water is accomplished by a pump that is operated by wave energy. 
     
     
         17 . The method of  claim 16 , wherein the pump is mechanical, electrical or electromechanical. 
     
     
         18 . The method of  claim 16 , wherein the pipe is made of FRP products.
