CRX100 Seafloor Excavator Tool Skid



The CRX100 is a seafloor excavator tool skid for integration with a work-class ROV. The excavator is designed for seafloor conditioning, collecting large samples from seafloor mineral deposits, and testing rock-cutting head designs at depth. The CRX100 can be configured with a bucket to clear the cutting area before the dual counter-rotating rock-cutting head is used to excavate material into the hydro cyclone for separation and recovery.
