TSHD Swalinge

Familiar and good

"The Swalinge"

The Swalinge was built as a coaster in 1977 and rebuilt into a trailing-suction hopper dredger after being purchased by Den Herder Seaworks in 1996.

The dry unloading installation was designed and built to our own specifications.
The average unloading time of the vessel takes 1.5 hours.

The hopper of the Swalinge is fitted with bottom doors so she can dump her cargo and she is also capable to use a shore delivery installation for pumping the cargo ashore.

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.
