Heerema Marine Contractors has received the first MHU4400S hydraulic hammer system from Menck, the Marine Foundations business line of Acteon. The delivery reflects the companies’ long-standing working relationship and aligns with Heerema’s stated approach to improving the performance, predictability, and efficiency of offshore foundation installation.

The MHU4400S will be added to Heerema Marine Contractors’ specialist equipment portfolio to support offshore crews working on increasingly complex offshore projects. The system is equipped with a Menck Noise Reduction Unit (MNRU) and is delivered with dedicated transport cradles, tools, and consumables. Heerema said the hammer will enhance offshore installation capability while supporting compliance with environmental regulations.

Menck developed the hammer to align with Heerema Marine Contractors’ existing power, control, and lifting systems. This compatibility is intended to enable efficient deployment across a range of offshore foundation installation campaigns.

With offshore energy projects scaling up, Heerema said the MHU4400S strengthens its ability to deliver installation work with an emphasis on safety and predictable execution. The company described the hammer as suitable for varied project environments and challenging seabed conditions.

Marcel de Nooijer, CEO of Heerema Marine Contractors, said Heerema continues to invest in assets that support its offshore operations and that equipment quality helps offshore crews deliver results on complex projects.

Jochem Scherpenisse, EVP of Marine Foundations at Acteon, said the companies’ collaboration is based on technical alignment and operational trust, adding that Acteon looks to continue supporting Heerema as it strengthens its fleet for offshore developments.

Heerema said adding the new hammer expands its available pile-driving capacity and supports operational uptime and project predictability. With two identical MHU4400S systems planned, the company said it expects increased planning flexibility and faster responses to upcoming project requirements.

The second MHU4400S hammer system is scheduled for delivery in October 2027.
