국내 최초의 육상형 해양심층수 취, 급, 배수시설 건설

The construction for Deep ocean water development in land-based system was carried out for the first time in Korea. The HDPE (high density polyethylene) pipe reinforced with wire rope or steep pipe under or on the seabed was installed in order to intake DOW at the water depth of 300m and 500m by hybrid installation method which uses the bottom pulling method in shallow water and surface tow method and laying ship method in deep water. The intake point of pipeline can be kept up at the 5m above seabed in order to intake fresh DOW with a intake frame structure. The pipeline for discharging DOW including even nutrition was installed with the surface tow method. The pump pit was constructed at the DL (-) 4.8 depth for a natural head of water. It is on a trial operation for stable pumping, and 1000 ton/day of DOW can be intake with the developed system.
