    ​​​MasterFlow 9800: bulk supplied high strength grout for sustainable and efficient offshore grouting operations

    • 25 years maintenance free operations
    • Relevant installation time and cost reduction
    • Northwester 2 wind farm project: successful cooperation between Jan De Nul Group and Master Builders Solutions®

    Master Builders Solutions® supports the development of wind power as a climate-friendly source of energy by offering our most advanced solutions for ensuring durability, full reliability of the assets and by aiding the successful construction of modern windfarms. In response to fast-changing new designs, extremely challenging environments and advancing technology, Master Builders Solutions experts have drawn on over 100 years of experience in the construction industry.
    “The construction of offshore foundations is challenging because you are building something in a harsh environment, where you need to consider the unique forces acting on a foundation by the wind turbine”, as explains Richard Elins, Operations Business Manager - Master Builders Solutions. MasterFlow 9800 is a bulk supplied high strength grout in the Master Builders Solutions portfolio for the wind industry that guarantees the fastest, safest and most cost-effective installation of offshore wind farms. Because of the bulk supply aspect, the continuous mixing and pumping equipment as well as the early strength development, MasterFlow 9800 ensures a relevant advantage during the building process, helping to reduce the total construction time and therefore the costs. In addition, due to extremely low autogenous shrinkage and its high fatigue resistance, MasterFlow 9800 ensures up to 25 years of maintenance-free operations even in roughest conditions, thus contributing to a sustainable energy solution.

    Offshore wind farm Northwester 2

    Jan De Nul Group, based in Luxembourg, is a specialized provider of services for the offshore energy and energy transition sector worldwide, which successfully completed in the past months the installation of twenty-three V164.9-5MW turbines and one offshore substation in the wind farm Northwester 2 off the coast of Ostend in Belgium. When approaching the Northwester 2 project, Jan De Nul Group was specifically searching for a sustainable grouting solution, also highly performing, cost efficient and reliable over time. MasterFlow 9800 was selected for this project, being able to meet and exceed all customer’s requirements. By applying MasterFlow 9800, Jan De Nul Group reduced the time of the grouting works by 50% and saved 15% installation costs. Thanks to its proven long-term durability, MasterFlow 9800 will also help the operator of the wind farm by ensuring up to 25 years maintenance free operation, a timeframe that covers the entire life cycle of the wind farm. On top of its high-level performances, one of the main reasons why Jan De Nul Group decided to choose MasterFlow 9800 has been the direct dialogue and collaboration established with the experts of Master Builders Solutions. Carl Heiremans, Business Development Manager at Jan De Nul Group, says “when we apply MasterFlow 9800 we don’t just expect a product delivery. We also wanted to understand the technology to apply it. And that's what we got.”
