How we work

MENCK supports all levels of the supply chain throughout the lifecycle of a project. With our superior expertise, a jacket structure will be securely anchored to the seabed in the most cost- effective way.

Utilising our extensive engineering know-how throughout all planning stages enables us to minimise any risk and optimise project performance where required.

Hammers & Spread

From 100 kJ to 3500 kJ, the MHU range of subsea hydraulic hammers represents over 140 years of experience in pile driving.

MENCK hammers are easy to operate, easy to maintain and maximize energy efficiency while striking hard. Delivering consistent energy for reliable pile driving above and under water, MENCK hammers are lightweight, with a small footprint and have many safety features.


MENCK provides the most common pile driving hammer sizes and spreads readily available for deployment across the world. Involving us in the planning stages as early as possible will enable us to reserve equipment and choose the most cost- effective and efficient method together.

We also support customers throughout the logistics and handling process, if required.
