Offshore wind farms operate in one of the most hostile environments, where extreme weather, saltwater, and harsh ocean currents put tremendous pressure on their foundation. Among the most critical components ensuring the structural stability of these massive turbines are grout seals. These often overlooked yet essential components create secure, durable connections between the offshore wind pile foundation and the monopile or jacket transition piece. The integrity of these foundations is vital, and that's where AIS grout seals come in.
Proven performance
AIS grout seals have been successfully installed across offshore wind projects worldwide, proving their reliability in offshore applications. These seals have been tested against the toughest marine conditions and have consistently demonstrated their effectiveness and high-performance.
Reliable sealing for secure foundations
AIS grout seals ensure a robust seal between the jacket or transition piece and the monopile during the grouting operation. This reliable sealing is essential for keeping the structure stable and secure despite the continuous motion and stress offshore wind foundations endure.
AIS Grout seals prevent contamination from mud and sand during the grouting process, which is crucial for ensuring the structural integrity of the foundation. Any contamination can compromise the strength of the grout and lead to potential long-term instability. AIS grout seals act as a protective barrier, protecting against these risks.
Innovative materials for maximum durability
AIS grout seals are engineered from high-performance materials, including neoprene rubber. This specialised rubber is designed to be both flexible and incredibly durable, allowing it to maintain a tight seal despite constant exposure to the harsh marine environment.
AIS grout seals are manufactured using a continuous moulding process, meaning there is no size limitation for the outer diameter. This makes them suitable for a wide range of offshore foundation designs.
For superior strength and resilience, AIS offers options for fibre reinforcement, which ensures that the seals can withstand extreme marine conditions and prevent grout leakage.
Our designs are based on Finite Element Analysis (FEA) models, developed from internal test results. This advanced design process ensures that each seal performs optimally under the specific stresses it will face in offshore environments.
Custom engineering for project specific needs
No two offshore wind projects are the same, and AIS understands that one-size-fits-all solutions don’t work in this sector. That’s why our engineers work closely with clients to develop grout seals tailored to their specific project requirements.
Our grout seals can be supplied in a wide range of sizes, accommodating both standard and custom specifications. Additionally, we offer different clamping solutions to fit the specific needs of each project, further enhancing installation flexibility and seal performance.
In demanding offshore environments, dynamic forces and wave motions are constant threats to structural stability. AIS grout seals are designed to handle reverse motion acceptance, maintaining their performance even under fluctuating stresses.
Why AIS grout seals?
Offshore wind foundations are under constant stress, and maintaining a secure connection between the foundation and turbine structure is critical. AIS grout seals offer the reliable sealing, contaminant prevention, and dynamic stability needed to maintain structural integrity while keeping the installation process efficient and cost-effective. By incorporating innovative material design, customisable engineering, and cutting-edge manufacturing techniques, AIS grout seals are essential in creating strong, lasting offshore foundations for offshore wind.
