TSHD Spauwer
Ultra modern
"The Spauwer"
The trailing suction hopper dredger Spauwer is an ultra-modern TSHD and has been designed and built in house by Den Herder Seaworks. This TSHD is specially designed for dredging within areas up to 65 meters of water depths.
By using spud poles, mooring actions are minimised. Before and during unloading, the load is pumped dry using a vacuum installation. he dry unloading installation is developed and designed by years of experience and is capable unloading the vessel in an average of 2.5 hours. The vessel is equipped with a special designed hydraulic screening plant so we can produce products as requested by our customers.
The key to success of the company is based on the highly skilled crew
and the high standard of maintenance which improves the reliability of our fleet. They form the strength of the company.
