This 60 ton subsea rake unit combines all existing technologies into a single tool. The new patented technology creates a reduced cost and increased efficiency solution for seabed clearance.  The new boulder rake requires reduced towing power and therefore reduced fossil fuel burn, and reduces the impact to the seabed by the use of spaced teeth which travel through the seabed in a similar way to an excavator bucker teeth could be pulled through sand or mud, catching the boulders and debris and moving them up into the flat blades of the rake, and off away to the sides.  Learn more.
