Description

The Controlled Flow Excavator (CFE) was developed for non-contact dredging operations, providing an efficient method of clearing material from subsea structures without contacting them.

Due to large hydraulic flow requirements, controlled flow excavators are typically powered directly from the surface, and as a result, often suffer from significant hydraulic losses in hoses. This issue can be eliminated by pairing the CFE with the UTROV®, which provides hydraulic power for the CFE at source.

The CFE can be fitted with different nozzle sizes to suit the soil densities expected on the project.
