Cable burial by ploughing has been clearly established as an effective and reliable method for burial of cables. Ploughs are simple tools that can be used offer fast progress rates and a work in a range of seabed types.
ETA specialise in providing unique plough systems dedicated to shallow water operations and shorter burial distances than many of the high cost market alternatives.
ETA’s focus on simple but effective engineering solutions mean bespoke ploughs can be designed and made often for a significantly lower cost. The ploughs are supplied with an easy to use control system similar to ETA's jet sled system.
