Drill rig 8 in the picture
  • Data acquisition on underwater drilling and blasting, and data transfer to volume calculation and dredging control systems.
  • Development of the complete process, including equipment for charging liquid explosives in underwater blasting.
  • Development of underwater drilling technology for demanding substrate conditions.
  • Development of a remote-controlled dredging fleet for cleaning of the sea bottom, which may contain explosives, for example.
  • Comprehensive development of backhoe dredging in general.
  • Development of controlled treatment of contaminated dredged sediments for beneficial use – funded by the European Union’s LIFE environments projects.

Continuous development in the field of harbour and marine construction has permanently created new practices and methods, such as retaining wall elements and special adaptation of drilling towers for underwater drilling and blasting.
