​First offshore foundations grouted at Gemini Offshore Windpark using the new bulk supplied material MasterFlow 9800 from BASF

Eemshaven, the Netherlands / Mannheim, Germany, August 10, 2015 - Only four months after introduction of the new bulk supplied offshore grout MasterFlow 9800 from BASF, the material is being used during the installation of the offshore foundations. at the 600 MW Gemini Offshore Windpark that is currently being built by Dutch Marine contractor Van Oord, in the Dutch part of the North Sea, approximately 85 kilometers north of the coast of Groningen.


The specialized grouting equipment of FoundOcean and BASF’s MasterFlow 9800 were mobilized at the harbor of Eemshaven. After installation of the monopiles and transition pieces with Van Oord’s offshore installation vessel Aeolus, the skirts were successfully back-filled using MasterFlow 9800.


The new MasterFlow 9800 high-strength grout was mainly chosen because of its unique delivery and installation method, which allows to considerably reduce the offshore grouting time as part of the foundation installation, and being able to work in the shortest weather windows possible. The first 48 of 150 monopiles/transition pieces were already installed and grouted. The monopiles were each grouted within 45 minutes, indicating the excellent offshore performance of the offshore crew and MasterFlow 9800 nicely allowing the contractors to follow the planned schedule.
