3D motion compensation system for 70-ton grab achieving an accuracy range within 20 centimeters
Boskalis and Tideway required a new deep-water dredging method 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 a full-3D motion compensation system. We also supplied the control system for the hoisting arrangement, which allowed for a high level of dredging automation and resulted in high production rates.
