Monopile collar installation at Kaskasi Offshore wind farm

Optimising grouting efficiency with tailored technology

Menck, Acteon’s Marine Foundations business line utilised its decades of experience in installation and deployed our SikaGrout®-9500  solution to grout the annulus between each monopile and collar. A pan mixing and pumping system was mobilised alongside material storage containers, an offshore laboratory, and a mobile workshop. 

Equipment strategically located across our global hubs was rapidly mobilised to meet project timelines, to enhance efficiency and reduce downtime, with logistics and crewing teams coordinating at short notice. By leveraging our strong supplier relationships, we achieved a rapid understanding of technical requirements, ensuring installation activities remained aligned with project specifications and schedules.

The result

We successfully supported the installation of three monopile stabilisation collars in an industry-first trial. The project showcased the value of responsive, integrated services in enabling offshore wind innovation against demanding timelines. The trial demonstrated effective collaboration across the supply chain and timely offshore execution under tight mobilisation conditions. Each collar passed the inspection, validating the process and supporting future adoption of the stabilisation method.
