Henriette


The M/S Henriette is a self-propelled work pontoon with bow door. It is especially suited for the use in inland waterways and in the shallow water areas at coasts.
It can fall dry, but it can also work as a semi-submersible pontoon. In the semoi-submersible configuration, it can reduce its own weight by up to 60 tons.

Depending on the work to be carried out, the M/S Henriette will be equipped with additional devices:
  • with a hydraulic excavator for dredging work and riprap work
  • with a cable-operated excavator for pile-driving work and
    other excavation work
  • with a Colcrete mixing plant with cement silos or with a
    Colcrete underwater placing unit, respectively.
