Abstract

A seawater intake had to be constructed for a diamond mine on the coast of Namibia just north of Oranjemund. The solution adopted consisted of a piled jetty with a dolos island on its seaward end protecting the pump chamber which was built of closely spaced concrete piles. The paper briefly describes the various problems encountered during the construction of the intake, including : limited penetration of the piles leading to the failure of the first jetty, serious slump of the initial dolos island, breakages of dolosse due to excessive movements during storms, considerable wear of the vertical spindle pumps due to sand and surging. Also described are the engineering solutions which had to be found at very short notice for immediate application.
