Motion compensation is becoming and accepted method to increase the accuracy and efficiency of hopper dredgers. Controllab has successfully developed motion compensation controllers for a wide range of access bridges, cranes and pile grippers. The same technology can also be applied for dredging. The basis of our success is a digital twin, i.e a 3D simulation model, that we create for every machine. The digital twin enables us to develop and thoroughly test the software before it is deployed.
