Trailing suction hopper dredger

Van Oord has a strong and modern dredging fleet of various trailing suction hopper dredgers. The new generation vessels currently being built will further modernise our fleet and improve our competitive position on different markets.

Trailing suction hopper dredgers are deployed for several dredging projects, such as:

  • Constructing and maintaining ports and waterways
  • Land reclamation
  • Constructing artificial islands
  • Coastal defences

Van Oord has 20 trailing suction hopper dredgers in its fleet:

  • Costa Verde
  • Dravo Costa Dorada
  • Geopotes 15
  • HAM 310
  • HAM 311
  • HAM 312
  • HAM 316
  • HAM 317
  • HAM 318
  • Lelystad
  • Pelican
  • Rotterdam
  • Utrecht
  • Volvox Anglia
  • Volvox Asia
  • Volvox Atalanta
  • Volvox Delta
  • Volvox Olympia
  • Volvox Terranova
  • Vox Máxima

Two princesses will be joining our fleet

Two trailing suction hopper dredgers, both with a hopper volume of approx. 18,000 cubic metres, are currently being built in Spain. The vessels have been named Vox Amalia and Vox Alexia, after two of the daughters of King Willem-Alexander and Queen Máxima of the Netherlands.

These vessels will strengthen the mid-class section of our hopper fleet. The vessels are characterised by a high deadweight tonnage in combination with a shallow draft, which makes them very competitive in various markets, including the market for coastal protection projects.

How does it work?

A trailing suction hopper dredger has large, powerful pumps and engines that enable it to dredge sand, clay, sludge and even gravel from sea or river beds. The vessel stores the dredged material in its own hopper and discharges the leftover water overboard. The hopper can be emptied in a variety of ways, including by:

  • depositing the material through doors or valves on the bottom of the vessel.
  • using pumps and jets to make the material fluid again and pump it ashore through a pipeline.
  • rainbowing, where the hopper contents are pumped directly from the vessel to the desired site.
