Acteon delivers first MHU4400S hammer to Heerema, strengthening offshore foundations partnership

Menck, Acteon’s Marine Foundations business line, has successfully delivered the first of two MHU4400S hydraulic hammer systems to Heerema Marine Contractors Nederland SE (“Heerema”) under a strategic multi-million-pound agreement.  

This milestone marks the first phase of a two-hammer supply agreement that reinforces the long-standing collaboration between Heerema and Acteon. The hammers will join Heerema’s extensive fleet of Menck’s systems, further strengthening its position among leading transport and installation (T&I) contractors.

The scope of supply includes the hammers with dedicated transport cradles, each accompanied by an innovative Menck Noise Reduction Unit (MNRU), and a custom set of tools, parts, and consumables – enhancing Heerema’s offshore installation capabilities while supporting compliance with stringent environmental regulations.

Heerema is a long-time client, partner and operator of Acteon's products and a key partner in technology developments that have shaped the offshore pile-driving industry. Menck’s flagship MHU4400S hammer continues this tradition, incorporating proven design principles with seamless integration into Heerema’s standards, power and control systems and lifting arrangements. Each hammer system includes the global navigation satellite system and Menck’s proven noise mitigation technology, ensuring compliance with environmental regulations and delivery performance across a range of foundation installation campaigns.

With just three months between contract award and delivery, Heerema gains early operational benefits while retaining the flexibility to optimise performance ahead of the second phase.

The second hammer system is scheduled for delivery in October 2027, supporting Heerema’s phased operational planning.
