Rockbags

Rockbags are used in the offshore wind industry to protect and stabilize cables and minimize scouring around assets such as wind turbine foundations. A Rockbag is a flexible container made of geotextile material that is filled with rocks or other heavy material. The bags can be customized in size and shape to fit the specific needs of the offshore wind farm.

One of the primary uses of Rockbags in the offshore wind industry is to protect underwater cables that connect the wind turbines to the main power grid. These cables are susceptible to damage from various sources, including fishing gear, anchor strikes, and scouring caused by waves and currents.

Rockbags are placed around the cables to provide a physical barrier that absorbs the impact of any potential threats, protecting the cables from damage.

Rockbags can also be used to stabilize the seabed around offshore wind turbine foundations. As waves and currents move sediment around the foundations, they can cause scouring, which can lead to instability and damage to the foundations. By placing Rockbags around the foundations, the bags absorb the energy of the waves and currents, reducing the scouring and stabilizing the seabed.
