This scheme comprises four wind turbines positioned just behind the sea wall adjacent to the River Mersey. Designed for the Liverpool Dock Company, the wind turbine foundations are positioned very close to unstable masonry dock walls. Our design incorporated foundations 4m thick upon which the wind turbines rest. These are in turn supported on large 1m diameter bored piles taken down to underlying sandstone. As part of our work on this project we carried out wind loading checks, fatigue verification, crack width analysis and spring stiffness assessment.
