Offshore wind: Concrete gravity foundations
Concrete gravity foundations (CGFs) provide the robustness and performance required to meet the engineering demands placed on foundation solutions. They also represent a step change in technology, one that can save costs compared with alternative approaches.
Offshore wind has a vital role to play in increasing our use of renewable energy – which in turn is essential to achieving energy security and reducing carbon emissions. By moving further out to sea and deploying larger turbines, more efficient energy outputs are achievable. CGFs can support these turbines, performing well in deeper waters and in challenging seabed conditions. Also, as demand for this solution grows, serial production will further reduce costs.
Concrete gravity foundations offer a solution for the majority of soils and water depths around the UK. Where rock is present near the sea-bed, they may well prove to be the only viable foundation type. There are a range of gravity foundations available, providing choice and competition thus ensuring a robust supply chain and cost-competitive solutions.
Benefits of concrete gravity bases include:
- Durable and long-life
- Generates UK jobs
- Low carbon
- Low maintenance
- No piling noise
- Reduced structural fatigue
- Suitable for deeper waters
- Suitable for a range of seabed conditions
- Utilises local materials
