Cadeler has completed the acquisition of Menck for 501 million euros, equivalent to approximately 578.1 million dollars, in a transaction aimed at expanding its transport and installation capabilities for foundations in offshore wind energy projects.
The Danish company, specialized in the installation of offshore wind turbines, will thus incorporate technology, equipment, and engineering expertise to reinforce its offering in fixed-bottom foundation projects. Menck will continue to operate as an independent company within the Cadeler Group.
Cadeler buys Menck and expands its capacity to install offshore foundations
The transaction was closed after obtaining all required regulatory approvals. Cadeler acquired Menck from Acteon, a British offshore energy services group that provides engineering solutions and operational support for offshore assets.
Furthermore, the acquisition will allow Cadeler to move toward a more integrated transport and installation model, known in the industry as T&I. The company seeks to combine its fleet of installation vessels with Menck’s specialized equipment and technical expertise.
The transaction has an agreed enterprise value of 501 million euros. To finance it, Cadeler utilized available liquidity along with a 380 million euro acquisition credit facility provided by DNB Bank and Coöperatieve Rabobank.
The company plans to subsequently refinance this facility through long-term financing and cash flow generated by its operations.
Menck to provide technology for offshore foundations
Menck has more than 150 years of experience in engineering applied to offshore foundations. Its portfolio includes hydraulic impact hammers, noise mitigation systems, drilling solutions, grouting, and specialized lifting and handling equipment.
Additionally, the company works on fixed-bottom offshore foundation projects and maintains an operational presence in Germany, the United Kingdom, Ireland, and Singapore.
Its technology is already part of projects executed by Cadeler. Among them is Hornsea 3, where Menck is supplying a 4,400 kJ impact hammer used in the installation works.
The previous relationship between both companies reduces the operational distance of the integration and offers Cadeler greater control over equipment considered critical for the execution of offshore wind foundations.
Menck to maintain commercial independence
One of the central elements of the acquisition is the decision to keep Menck as an independent company. In this way, it will continue to serve other contractors in the offshore wind market and maintain its commercial identity.
Cadeler believes this structure will allow Menck to preserve its client relationships and operational knowledge while leveraging synergies in joint projects.
Cadeler CEO Mikkel Gleerup explained that the growth in size and technical complexity of offshore wind farms is increasing the importance of reliable execution.
According to the executive, combining Menck’s engineering capabilities with Cadeler’s experience in offshore operations will allow them to serve a larger part of the installation value chain.
Acquisition reduces dependence on subcontractors
With the incorporation of Menck, Cadeler expects to use equipment destined for offshore foundations more efficiently and reduce its dependence on outsourced services.
The company also expects to gain flexibility in project planning and execution. This is particularly relevant in large-scale installations, where the availability of specialized equipment can directly influence construction timelines.
Both companies also share a model based on leveraging high-value assets through technical knowledge, operational experience, and high utilization levels.
For Cadeler, this combination can reinforce the resilience of its operations and offer a broader solution to offshore wind farm developers.
Cadeler reinforces its position in offshore wind energy
Cadeler operates one of the largest fleets of jack-up vessels for offshore wind turbine installation. The company is progressively expanding its activity toward the integral transport and installation of foundations and operation and maintenance services.
In June 2026, it completed the installation of 100 Siemens Gamesa wind turbines at RWE’s Sofia offshore wind farm, with a capacity of 1.4 GW in UK waters.
With the acquisition of Menck, the company expands its presence in another critical phase of offshore projects: the installation of the foundations that support the wind turbines.
The combination of fleet, engineering, and specialized equipment places Cadeler in a broader position within the offshore wind installation market and allows it to assume a greater proportion of the technical activities required before turbine assembly.
