NorthWind offshore first to use grout with a compressive strength of 180 to 200 MPa

71 monopiles and one substation were grouted during this project,

ITW Polymers Europe (former Densit) provided the full grouting package with the use of their innovative UHPC product, Ducorit D4 at NorthWind wind farm in Belgium. The project, which began at the end of March was performed by ITW Polymers Europe for GeoSea on board of the VOS Sympathy vessel.

Fatigue properties and extreme strength of grouting were especially important for GeoSea because the company always sets focus on safety and cost efficiency. That is why Ducorit D4 UHPC grouting material with a compressive strength of 200 MPa was chosen for this project. This is the first time ITW Polymers Europe has supplied a full grouting package with the use of Ducorit D4.

The project was developed by NorthWind NV and is located on the Bank Zonder Naam in the North Sea. Although 71 monopiles and one substation were grouted during this project, there is one monopole to be grouted and this is expected to be completed at the beginning of 2014. After completion, the wind farm will be able to generate 216 MW from 72 Vestas, V112 3MW turbines.
