Dudgeon Offshore Wind Farm

The Dudgeon Offshore Wind Farm is located 20 miles off the coast of Cromer in North Norfolk, around 14 miles north-east from the operational Sheringham Shoal Offshore Wind Farm. The 402MW capacity wind farm consists of 67 6MW turbines and a single offshore substation platform.

Kent was commissioned to undertake the concept, FEED and detailed design of the 67 individual monopiles & 67 individual transition pieces, designing a monopile with a diameter of greater than 7m, which at the time was larger than any other previous designs. Additionally, the monopiles were installed at locations with water depths up to 36m – the deepest application of this foundation type at the time of installation.

As well as the design of monopiles and transition pieces, Kent was responsible for the following project activities:

• Geotechnical analysis and engineering, resulting in no pile refusal during installation
• Structural, electrical, process and utilities design
• Structural analyses (including the full in-place, load-out, transportation and lift analyses for all structures)
• Interface management assistance between design, fabrication and installation contractors
• Fatigue analysis, ship impact, redundancy and seismic redundancy
• Post-fabrication, transport & installation management assistance
