The Stevin 80 is a new dredge that its makers, Volker Stevin Dredging of the Netherlands, say can handle marine mining and harbor building operations previously stymied by rough wave and soil conditions, high seas, and rocky ocean beds. The dredge, a prototype of which is currently under construction in Rotterdam at a cost of $100 million, is 623 ft long by 220 ft wide and weights about 29,000 tons and will be ready for use by the end of 1979. Its designers claim the new dredge makes it possible to design and build ports in locations previously considered unrealistic because of adverse conditions. They add that the dredge also will allow harbor dredging without waiting for construction of breakwaters. In addition, it could open up new possibilities for pipeline trenching in rough coastal waters, and for coastal mining adventures such as potential mining of phosphate deposits on the coast of Northwest Africa, mining of gold and platinum deposits on the Alaskan north slope, and mining of diamonds off the coast of Namibia in Southwest Africa.
