Grab excavator dredge cycle automation yielding high accuracy and production rates
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 the controls of the hoist winches. The complete system was executed with full dredge cycle automation. Thanks to its advanced control system, the highly automated GES excelled: production rates of 150 m3/hour in 750 kPa stiff clay at an accuracy level of 20 centimeters were achieved.
