OFFSHORE WIND

Ultra-High Density Stone for Offshore Wind

Norock supplies ultra-high density stone (~3.2 t/m³) for scour protection and seabed stabilisation.
Compared to standard materials (2.6–2.7 t/m³), our stone delivers:

  • Greater stability under strong currents and waves

  • Reduced stone volumes needed for the same effect

  • Faster installation offshore with fewer vessel days

  • Possibility of one-layer scour protection instead of 2–3 layers

  •  Lower total project costs

With typical gradings ranging from 10–60 kg, 5–40 kg, 3–9 inch, 2–8 inch, 1–5 inch, and 63–200 mm, we also offer custom gradings tailored to specific project requirements.

Our stone is trusted at every stage of foundation works, whether to:

​

  • Stabilise and level the seabed with an initial placement layer

  • Provide a fine filter or bedding layer

  • Form the final scour protection system

 

Thanks to its exceptional density and durability, we have become the preferred scour protection supplier for leading offshore wind farm developers and contractors worldwide.
