Currently Den Herder Seaworks operates three Trailing Suction Hopper Dredgers, specially designed and built for the extraction of sea aggregates. Den Herder Seaworks delivers and unloads its products / loads to their clients and buyers within Europe.

The operating company Spauwer Marine Aggregates B.V. finalised the construction from the Spauwer in April 2017. The Spauwer was designed and built in-house. By using the most modern dredge- and screen techniques on our vessels, we can supply our clients and customers fast and efficient with sea aggregates of high quality.

Due to the presence of the very advanced unloading methodology onboard on all our vessels and the ability to use spud poles present on several of our vessels, we can unload fast, independent and efficiently.

All our TSHD’s have a high company standard of maintenance and are built under Class requirements of Lloyds Register or Bureau Veritas.
