Cadeler has taken over Menck, a German firm that designs and supplies equipment and technology for installing offshore wind foundations. The deal, confirmed on August 13, 2026, will keep Menck operating as an independent unit within the Cadeler group, preserving its market position.
Menck brings a deep operational history, with more than 150 years of experience, and a substantial data asset: over 50 million data points collected from driven piles. This information can help refine foundation installation techniques for future projects. As part of the integration, Menck is already providing a 4,400 kJ impact hammer for Cadeler's Hornsea 3 project, one of the largest offshore wind farms under development.
"Offshore wind projects continue to increase in scale and technical complexity, making reliable execution more important than ever. Menck has built an outstanding reputation over more than 150 years as a trusted provider of mission-critical foundation installation equipment and engineering expertise. Bringing together Menck’s specialist engineering capabilities with Cadeler’s offshore installation proficiency, we are combining highly complementary strengths that will enhance our support to customers across the full installation value chain," said Mikkel Gleerup, CEO of Cadeler.
In a separate development, Cadeler has finished installing the last turbine at the 960 MW He Dreiht Offshore Wind Farm in the German North Sea. The final units were placed by the Wind Keeper vessel, which operates under a long-term contract with Vestas. This milestone marks the completion of a major project for Cadeler, demonstrating its ability to handle large-scale offshore wind installations.
The Menck acquisition and the He Dreiht completion together highlight Cadeler's expanding role in the offshore wind sector, from foundation work to turbine erection. By keeping Menck standalone, Cadeler aims to retain its specialized knowledge while leveraging the parent company's broader resources. The company says this combination will allow it to offer a more integrated service to customers, addressing the growing demand for reliable and efficient installation methods in the industry.
