Diver Dredge [Data Sheet]
GTO® Dredging systems are designed for efficient removal of large quantities of sediment subsea.

The 6 inch Diver Dredge is a stand-alone subsea package that is deployed to the sea floor via vessel down-line. A diver manipulates the dredge pick-up (nozzle).

The dredge is hydraulically-powered from the support vessel, with a high-flow, low-pressure seawater pump discharging through a venturi system.

The dredging units can be can be utilized for excavating underground pipelines, salvage, and other similar offshore applications where large amounts of soil removal is required.

Subsea Dredge [Data Sheet]
GTO® Dredging systems are designed for efficient removal of large quantities of sediment subsea.

The 12 inch Subsea dredge is a stand-alone subsea package that is deployed to the sea floor via a separate electrical umbilical. A work-class ROV accompanies the dredge system and manipulates the dredge pick-up (nozzle).

The dredge is electrically-powered and drives a high-flow, lowpressure seawater pump discharging through a venturi system.

The dredging units can be can be utilized for excavating underground pipelines, salvage and other similar offshore applications where large amounts of soil removal is required.

This system is suited for large amounts of debris removal and increased soil hardness.

ROV Dredge [Data Sheet]
GTO® Dredging systems are designed for efficient removal of large quantities of sediment subsea.

The 6 inch Remotely Operated Vehicle (ROV) dredge is integrated to a work-class ROV of opportunity and is hydraulically-powered by the ROV’s hydraulic pumps. The hydraulic energy powers a high-flow, low-pressure seawater pump discharging through a venturi system.

The dredging units can be can be utilized for excavating underground pipelines, salvage and other similar offshore applications where large amounts of soil removal is required.
