The foundation for rocky seabed ROCKMAT is an innovative concept of offshore wind foundations adapted to rocky or uneven seabed.

ROCKMAT is a patented technology for an interface between soil and a superstructure (jacket, monopile, concrete base). It consists of a smart combination of a grout injection system, associated to jack levelling system.

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.

  • No site preparation
  • No costly lifting barge crane
  • Reversible water ballasting

ROCKMAT has been patented by CETEAL, Cathie Associates (offshore geophysics and geotechnical) and DV Offshore (marine operations).
