Known as the “Gentle Giant,” the MENCK MHU 3500S hydraulic hammer exerts a massive 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 two to three db quieter than some of MENCK’s smaller hammers, meeting extensive environmental protection requirements,” said MENCK’s international marketing manager, Claas Denkmann.
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.
“This particular hammer drives extremely large monopiles quickly and efficiently, helping to build strong foundations for the tallest wind turbines,” said Denkmann. “Project Sandbank is an exciting project for MENCK, not only because of its size, but also its location off the coast of Germany.”
Owned by Vattenfall AB (one of the biggest wind power operators in the UK) and Stadtwerke München (which supplies electricity for more than 95 per cent of Munich’s 750,000 households), the Sandbank Offshore Wind Farm project is due to be constructed in 2015, 90 kilometres off the coast of the German island, Sylt, in the North Sea.
The wind turbines for Sandbank will be installed over a total area of 59 km2 and each turbine will measure 160m high, with rotor diameters of 130m. Bilfinger Marine & Offshore Systems will operate the innovative MENCK equipment to drive the monopiles into the seabed.
The new wind farm will consist of 72 four-megawatt Siemens turbines with a total maximum installed capacity of 288 megawatts. The expected electricity generation is equivalent to the yearly consumption of approximately 400,000 average German households. MENCK GmbH provides a range of specialized hydraulic pile driving solutions for wind farm projects globally, but also supports the offshore oil and gas industry and civil construction projects such as bridges and harbors.
MENCK GmbH is an Acteon Company with 40 years of industry experience, delivering unprecedented engineering and pile driving knowledge from its team of highly trained offshore service technicians. For more information about MENCK, visit www.menck.com.
