Extremely productive deep-water dredging at very high accuracy levels
A new deep-water excavation method was required to excavate in challenging soil conditions at a water depth of 150 meters. To this purpose, the Grab Excavation System (GES) was developed.
Seatools designed and built the grab-positioning ROV and its control system, including full-3D motion compensation. The highly automated GES excelled: it enabled Boskalis and Tideway to excavate at a water depth of 150 meters with production rates of 150 m3/hour in 750 kPa stiff clay at an accuracy level of 20 centimeters.
