The new PVE 500MU Upending Vibratory Hammer

Recently, Dieseko's newest offshore Upending Vibratory Hammer has been passed the FAT-test and is now DNV-certified for offshore lifting appliances. This machine has been developed for the efficient and safe installation of Anchor Piles and Pin Piles in the renewable energy market.

The past two years have been dominated by the development of this new machine. In the monobloc segment, this is the largest Vibro Hammer ever built. Important developments are the newly designed tilt bracket, the increased lifting capacity and a hydraulic safety lock during upending.

Power & Emission
Low-emission and zero-emission are key. This important aspect is also part of Dieseko’s strategy. Two coupled PVE 1600, Stage-V, Power Packs provide the required 3,200L oil flow. Controlling the clamps and the upending and locking system is done with a 100% emission-free electric-hydraulic power unit.

Dirk Smulders – CEO: Our team has great drive and enthusiasm to support and accelerate the energy transition by innovative foundation solutions. This new 500MU development is a great example of that."

Technically, the 500MU is made up of 2 gearboxes of 250 kgm each. The machine will also be available as a 250MU (250kgm) version.

Stacked gearboxes are also used for the Dieseko GIANT concept: Several gearboxes are placed on one base as a modular system, as required, up to 2,000 kgm eccentric moment. In 2022, Dieseko Group will supply a PVE Upending GIANT 2,000kgm eccentric moment Vibratory Hammer for installing 64 Monopiles offshore the Coast of Bretagne in France.

The 500 MU will be deployed at the end of 2021 to install anchor piles for wave energy floats.

The PVE 500MU is designed to install:

Anchor piles

Anchor piles are the mooring solution for floating renewable devices. Anchor piles bring various benefits in terms of transferring high loads in multiple directions. This allows mooring of various floating structures, such as Semi-Subs, SPAR’s, FPSO’s and TLP’s.


Pin-piles secure subsea structures to the seabed. This can be, for example, tripods for the foundation of windmills

Pierre Bouchet – Mechanical Engineer: Rule #1 in the field of offshore; no surprises! So we test, test and test until everything is 100% perfect. "

PVE 300MU, the first Upending Vibro Hammer ever

The PVE 500MU is a further development of the patented PVE 300MU Upending Vibratory Hammer. Dieseko’s Upending concept was already introduced in 2012 on the Global Tech I wind farm.

In this project 240 PIN piles, up to 60 meters in length were picked up, positioned and vibrated directly for the first time in history, without an auxiliary crane. With this efficient way of installation, Dieseko has opened the eyes to the use of Vibratory Hammers in offshore applications.
