Offshore Foundations

Now that the industry has recognized the advantages of this technology, the development of vibrating solutions has accelerated enormously. Vibro technology benefits offshore foundations because of its installation speed and handling and is increasingly changing offshore foundation methods. About 15 years ago, Dieseko installed the first anchor piles in submarine soil. Shortly afterwards, Dieseko started coupling vibratory hammers in tandem for more power to install monopiles.

Dieseko’s patented Upending concept was already introduced in 2012 on the Global Tech I wind farm.

In 2011, Dieseko manufactured the PVE 300M, the biggest vibratory hammer ever built. In 2012 this vibratory hammer was made tiltable so that it could up-end piles and used very successfully in the Hochtief Wind project.

The growing demand for wind and renewable energy requires fast and efficient installation methods. Dieseko offers innovative solutions, for example for installing anchor piles as a mooring solution for floating renewable devices or pin-piles as fixators for subsea structures.

• High installation speed
• Limited piling noise
• Limited impact
  • Prevents damage to marine life and, improves working conditions on the installation vessel for the construction team
• Easily adjustable for different tube diameters
  • Our GIANT Vibro can be easily reconfigured to drive piles from 3.5-8.4 meters in diameter
  • Changing pile designs and increasing pile diameters call for modular equipment

• Shortens pile driving times
  • Tests show that under suitable soil conditions the vibratory hammer drives down the pile 10 times faster
  • Complete the foundation work within short weather windows due to efficient handling
• Brings down installation costs by deploying fewer and more economical tools
  • The pile is lifted, positioned and directly driven into the seabed without the use of a pile gripper or positioning frame or auxiliary lifting crane

Dieseko is currently deploying a newly built 500MU Upending vibratory hammer. And we will start manufacturing the 2000MU Upending Giant this year. This Giant will be another first of the most enormous vibratory hammer ever built. This Giant allows monopiles with a diameter of up to 8.40m and a weight of 1600 tons to be installed.
