    MasterFlow 9800: bulk supplied high strength grout for offshore wind turbine foundations.

    Where and how does MasterFlow 9800 work?

    Wind turbines are special – their safe and durable installation largely depends on the correct design and interaction of all components – and require a high performance MasterFlow Exagrout to guarantee long term and maintenance free operation of the wind farm. MasterFlow 9800 is a new generation of high strength, fatigue resistant grout for grouted connections used in offshore installations like jacket foundations or monopiles with bolted connections.

    What makes MasterFlow 9800 a unique solution?

    MasterFlow 9800 is bulk supplied offshore grout which is installed using a continuous mixing & pumping equipment, with the aim to increase productivity and safety during grouting works. The material exhibits long term durability and guarantees a fast, secure and cost reduced installation of the offshore wind farm. High early and final strength, and excellent fatigue resistance makes this material uniquely suitable for structures that are exposed to very high dynamic loads, e.g. high wave actions and wind loads in offshore conditions.
    The high early strength development of MasterFlow 9800 and the possibility to install the material in temperatures as low as 2°C, allow the material to be installed in the shortest weather windows possible. Unmatched grout output rates of = 20 m³/h allow the fastest application possible.
    Short overall installation times and earlier operation of the wind farm guarantee faster energy production, earlier return on investment and safeguard project completion on time.

    MasterFlow 9800 meets customer demands of all value players in the offshore market, and offers a wide variety of benefits.

     Excellent durability:

    • High fatigue resistance, absorbing dynamic loads
    • Volume stable
    • High flexural strength
    • Lower modulus of elasticity, less brittle grout
    • Very low porosity and water absorption
      Secure installation:
    • High early strength development reducing the risk of early age cycling
    • Excellent long term load transfer
    • High ultimate strengths
      Fast and cost effective installation:
    • Rapid strength build-up, even at cold temperatures
    • Short overall installation times and earlier operation of the wind farm
    • Faster energy production and earlier return on investment
