The Sandbank Offshore Wind Farm project is 90km off the coast of the German island, Sylt.
MENCS says the Gentle Giant, the MENCK MHU 3500S hydraulic hammer, is the largest and most powerful hydraulic hammer in the world. The hammer exerts 6.2kJ per tonne of weight, with a pile sleeve that is 6.5m in diameter.
"The MHU 3500S has a proven higher output than any other hammer in the world, yet it is up to 2-3db quieter than some of MENCK's smaller hammers, meeting extensive environmental protection requirements," says Claas Denkmann, international marketing manager. “This particular hammer drives extremely large monopiles quickly and efficiently, helping to build strong foundations for the tallest wind turbines."
Engineered in Germany, the unique MHU 3500S hydraulic hammer is available as part of MENCK's extensive rental fleet and can be deployed anywhere in the world.
Owned by Vattenfall and Stadtwerke MünchenIt, Sandbank is due to be constructed in 2015 and is the successor of Project ‘DanTysk'.
The wind turbines for Sandbank will be installed over a total area of 59sq kmand each turbine will measure 160m high, with rotor diameters of 130m.
Bilfinger Marine & Offshore Systems GmbH will operate the MENCK equipment to drive the monopiles into the seabed.
The new wind farm will consist of 72 4Mw Siemens turbines with a total maximum installed capacity of 288Mw. The expected electricity generation is equivalent to the yearly consumption of approximately 400,000 average German households.
