Aboard the giant sand-sucking ships that China uses to reshape the world | MIT Technology Review


In recent years, China has assembled an armada of oceangoing dredges. Some it buys from Japan, Belgium, and the Netherlands.

Increasingly, though, China manufactures them itself. China’s homemade dredges are not yet the world’s largest, nor are they any more technologically advanced than those of other countries, but it is building many more of them than any other country.

In the past decade, Chinese firms have built some 200 vessels of ever greater size and sophistication. In 2013, Rabobank, a Dutch firm, declared that China’s dredging industry had become the biggest in the world, and it has only grown since then. Chinese firms bring in as much revenue from domestic dredging as is accrued in all of Europe and the Middle East combined.

Since 1985, according to Deltares, a Dutch research group, humans have added 5,237 square miles (13,564 sq km) of artificial land to the world’s coasts. China is a major—and growing—contributor to that total.
