Monopiles

The monopile foundation is the most common foundation type presently installed in offshore wind farms

When choosing the monopile foundation, a project can draw on a range of experienced contractors in marine steel design.

The monopile foundation has a long track record in the offshore wind farm industry. The monopile solution is based on design experience from the offshore oil and gas industry which has been adapted for the offshore wind farm industry.

New and optimised designs

 

As the offshore wind farm industry sets new requirements to the design practice, recent experience has lead to new and innovative solutions for specific components such as the grouted connection.

These solutions are implemented in the COWI design, which reflects the most recent knowledge developed within monopile foundation design. These designs are certified by DNV.

London Array
As lead designer on the largest offshore wind farm in the world, the 630 MW London Array offshore wind farm, COWI has now taken the lead in the design of monopile foundations. 

The London Array offshore wind farm comprises 175 monopile foundations in water depths varying from 0 to 25 metres in different soil conditions. The piles have a 4.7 metre or 5.7 metre diameter, and the foundations attain total lengths of up to 85 metres.

The London Array foundations were designed in a COWI lead joint venture with IMS for Aarsleff-Bilfinger|Berger JV.
