We design, build and support dredge equipment

De Klop and De Hollandsche IJssel since 1872 In the heart of the dredging industry.

Around 1900, the Sliedrecht brothers Arie, Eliza and Jacob van Noordenne set up a repair shop in Zuilen to repair the equipment they used in their dredging and contracting work. After a number of years, the construction of new equipment also took place here, and a shipyard was created where the first ship was launched at the end of 1906. The shipyard was named after the nearby Fort De Klop.
