Used as a method of bulk rock or gravel deployment, our subsea rated drop bags are designed with a large chute in the base and lifted and activated using one of our standard quick-release frames or beams. Commonly available in 1t & 2t sizes, we can source and supply pre-filled bags using locally sourced rock or aggregate. Rock can be supplied certified to a certain grade or density as required.

Rigged up to one of our specialist frames or beams, multiple bags can be installed simultaneously and activated either by a diver, ROV or using our hydraulic release kit (HRK)The bag is then recovered to the surface. This method can offer huge cost reductions compared to conventional rock dumping as a much less capable vessel is required.
