The Vortex 6 inch is designed for subsea excavation and disposal of sediments and gravel up to 140 millimetres. It is easily mounted to the ROV and requires no ship deck space and sea fastening. The vortex 6 inch requires no specialist operator or additional cables between ship and sea floor.

It has an optional jetter kit for breaking up seabed. The low-hydraulic consumption leaves enough hydraulic supply on most ROV’s to utilise a purpose built high pressure jetter unit if the task requires one.This 6 inch dredge has shown under real-world conditions to provide suction performance of 64kpa using the patented vortex venturi. Removal rates are actual figures using magnetite iron sand and rocks at 2.375kg per litre.
