Rijkszee- en Marinehaven Den Helder Subsurface grout removal steel tubular pipe

For our client Ballast Nedam Marine & Civiel B.V. Aqua Demolition Services B.V. (ADS) has solved a difficult problem at the port of Den Helder, The Netherlands. As a result of a collision an existing steel tubular pile had to be made accessible for further construction activities.
A concrete plug with a dimension of 1.5 meter had to be removed below the waterline to a depth of 3 meter.
No problem for ADS! Subsurface hydrodemolion needs customisation for our principals. For this project a special auxiliary structure was connected to a construction crane in order to align the demolition nozzles.
Safety and precision were assured at all times!
