Abstract

1373890 Seabed dredging CENTRE NATIONAL POUR SEXPLOITATION DES OCEANS and LE NICKEL 11 May 1973 [25 May 1972] 22694/73 Heading E1F Solid products such as polymetallic nodules are continuously extracted from the seabed by employing two ships 1, 2 and an endless dredging line 3 equipped with buckets; the line being fed down to the seabed by ship 1, drawn back after dredging to ship 2, then passed back to ship 1 along a return path 11 which is at least partially submerged. In an alternative way of performing the operation three ships and two dredging lines may be employed (Fig. 2 not shown): two lines are raised from the seabed after dredging to a common extractor ships and are passed back one to each of two laying ships on each side of the extractor ship.
