Sedimentation and siltation are natural phenomena, and a permanent threat to navigation and accessibility of ports.
Maintenance dredging requires a lot of knowledge about the dynamics of an estuary, and even more experience on how to deal with tides, currents, flood channels, bars, bends, and the various nature of suspended material.
It is carried out with respect for the environment, reducing overflow and limiting turbidity. Moreover, smart dredging supports the natural processes and uses the river dynamics for keeping the gateways open.
Sophisticated software and automation onboard off DEME vessels secure increased performance and optimized monitoring.
