The new PVE 500MU Upending Vibratory Hammer

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

Development
Over the past two years Dieseko engineers have focused on the engineering of this new machine. It is the largest vibratory hammer ever built! The engineering challenges led to important innovations including a newly designed tilting bracket, increased lifting capacity, as well as a hydraulic safety lock that is activated during the pile upending procedure.

Specifications

*) for vibrating, clamps and locking

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.

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.”

PVE GIANT and 250MU

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

ICE 250NF

Stacked gearboxes are also used for the Dieseko GIANT concept: the gearboxes can be used as building blocks to build up a vibrator with up to 2,000kgm of eccentric force. Each 250kgm or 500kgm modular gearcase added to the base plate increases the working range of the unit. 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.

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

Anchor piles

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

Pin-piles

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

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 first introduced in 2012 at the Global Tech I wind farm in Germany.

300MU in Hochtief Global Tech I project

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 opened the eyes of the world to the use of Vibratory Hammers in offshore applications.
