Deep C Subsea Dredging, Excavation and Jetting

Deep C subsea dredging and excavation solutions deliver high-performance seabed intervention through a combination of tracked vehicles, ROV-operated dredges, and integrated jetting systems—ensuring efficient material removal and full asset exposure in complex offshore environments.

Powered by the Deep C SCV, a high-capacity subsea construction vehicle with up to 20” unrestricted dredging and removal rates of up to 50 m³/hr for rock and 150 m³/hr for soft soils, operations are optimized for both large-scale excavation and precise intervention around subsea structures. The vehicle can also be used for UXO clearance, survey and inspection, decommissioning and other construction support.

For flexible and targeted operations, Deep C HD Subsea Dredges and ROV dredging systems provide up to 16” unrestricted flow and high-capacity sediment removal, with the ability to operate dual dredges simultaneously and integrate jetting for cohesive soils.

To enhance performance in dense or compacted seabed conditions, the Deep C® Subsea HP Jetting System is deployed directly on the seabed, eliminating energy losses from topside supply while reducing deck footprint and improving offshore safety. This integrated approach enables efficient excavation, controlled spoil management, and complete 360° access to subsea assets.

The result is fast, controlled, and predictable dredging operations—minimizing vessel time, reducing offshore personnel, and ensuring optimal preparation for cutting, lifting, and recovery activities.
