Abstract

An ocean water drawing system includes: a well; a working tunnel disposed underground and having an end segment distal from the well; a pipeline unit including a primary pipeline disposed in the working tunnel, and having one end extending sealingly into the well and the other end extending through the end segment of the working tunnel and into an ocean so as to permit ocean water to flow into the well through the primary pipeline; and an access tunnel isolated from the well and extending downwardly from a ground surface to intersect the working tunnel so as to communicate spatially with the working tunnel and so as to permit access into the end segment of the working tunnel for operation and maintenance of the primary pipeline.
