WeSubsea's Titanium Hybrid Dredger Systems

The WeSubsea hybrid dredging system is a standalone diver/ROV dredging and jetting unit designed for the
excavation of stiff and hard clay.

Our unique systems are the first to offer high powered dredging and true jetting performance in a compact and
easy to use package.

The system requires no additional topside equipment or separated down lines and utilises the HPU and umbilical
already powering the dredger. This greatly reduces cost and the deck space required.

The system can be safely operated by diver or ROV with the capability of switching on and off the jetting system
subsea as and when required.
