ROCKMAT is an innovative and patented concept of offshore wind foundations adapted to rocky or uneven seabeds.br br With no site preparation or drilling, ROCKMAT is a lower cost solution that can be implemented using only the local industry and at no cost to the marine environment.br br ROCKMAT is a self-floating foundation, lowered by hydrodynamic ballast. Accurate leveling is achieved by a system of underwater jacks. Concrete is injected in flexible cofferdams bags to fill in seabed irregularities of 1 meter, eliminating the need for site preparation.
