Acteon today announced the sale of Menck, its Marine Foundations business line, to Cadeler A/S (or “Cadeler”). The transaction marks an important milestone in Acteon’s transformation and advances our strategy to build stronger, more focused businesses serving our offshore energy customers.

Acteon’s next chapter

Over the past two and a half years, Acteon has reshaped its strategy, structure and market position, creating a stronger company built around four focused business lines.  Today, we announce an important transaction resulting from that work. Cadeler has acquired Menck, accelerating Menck’s plans to grow by expanding the way it supports its customers. 

With the investment of Cadeler, Menck will be better positioned to accelerate investment in its market-leading marine foundations capability and support its customers’ evolving needs.  For Acteon, the transaction strengthens our ability to invest in our other business lines.
 

Cadeler has acquired Menck

Cadeler, a leading offshore wind installation contractor and operator of the industry’s largest fleet of jack-up wind installation vessels, has acquired Menck. Menck will continue to operate as a standalone company, and our ownership will not change how we support our customers and approach projects.  

Joining Cadeler marks an exciting new chapter for Menck. With Cadeler’s support, we have a strong platform to further develop our business and continue to deliver trusted solutions to our customers across the wind industry and beyond.   

As a leading offshore wind installation partner, Cadeler understands the critical role Menck plays in the industry's supply chain and shares our long-term commitment to quality, engineering excellence and reliable project execution. Cadeler will strengthen Menck’s financial flexibility to support and accelerate the execution of our continued growth plan. 

Our acquisition by Cadeler reflects the expertise, technology and strong reputation that we have built over more than 150 years. Under our new ownership, Menck will continue to operate as a standalone business, as we all know it today. There will be no changes to our ongoing projects, nor the people and expertise our partners rely on.  

The long-term relationships we have built with our customers remain at the heart of our business, and Menck will continue to serve our valued customers across the offshore wind industry (including other installation contractors) and beyond.
