Van Oord has developed an hydrodynamic dredging technique called water injection dredging (WID). It is an efficient way of maintaining the depth of a port or river. Because of its excellent manoeuvrability, the vessel can dredge very close to embankments and quay walls. This equipment is normally used on small projects, but water injection dredgers Iguazú and Antareja were also part of the impressive fleet that worked on the Second Suez Canal.
Van Oord has 10 water injection dredgers in its fleet:
- Draga Rio Madeira
- Draga Tocantins
- Sagar Manthan
How does it work?
Someone who knows everything about WID is Van Oord Engineering Geologist Marcel van den Heuvel. ‘WID is an efficient way of maintaining the depth of a port or river. The innovative characteristics of WID are often not covered by local legislation governing dredging permits. We consider all concerns that our clients and stakeholders may have. A test period combined with a monitoring program is the best way to make our clients, consultants, stakeholders and legislatures confident in the WID method we use.’ It is a clear example of Marine ingenuity.
Van Oord’s water injection dredgers are deployed worldwide. Water injection dredging has been used widely in India, Brazil, and northwestern Europe for many years. WID vessel Jetsed works mainly in the United Kingdom and the Netherlands. The longest-running WID contract is the 19-year maintenance dredging contract in São Luís, Brazil. On the other side of the globe, WID vessel Sagar Manthan has been deployed to Indonesia.
