Bombeo de deep seawater (PDF).

In the area of deep-sea water suction technology, Furukawa Electric has built an excellent  track record of laying eleven deep-sea water suction pipes in seven locations since its first domestic laying in Muroto City, Kochi Prefecture in 1988. During this time, we have introduced various improvements in the laying method as well as in the design of material structures including suction pipes, thereby making it possible to manufacture and install the suction pipes up to 280 mm in diameter, 680 m in laying depth, and 7200 m in pipe length
