22.12.14 MENCK Providesworld’s Largest Hydraulic Hammer For Sandbank Wind Farm Construction.

Subsea pile driving specialist Menck is providing the largest and most powerful hammer in the world to assist Bilfinger Marine & Offshore Systems with the installation of subsea foundations for Project Sandbank, a new 72 turbine wind farm in the North Sea.

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 proven a 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 International Marketing Manager, Claas Denkman.

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 monopoles quickly and efficiently, helping to build strong foundations for the tallest wind turbines," says Claas. "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 Munchen (which supplies electricity for more than 95% 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. It is the successor of Project 'Dan Tysk'.

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. One of the market leaders in the offshore wind energy sector, Bilfinger Marine & Offshore Systems GmbH will operate the innovative MENCK equipment to drive the monopoles into the seabed. Hamburg based Bilfinger has gained significant experience in design, supply, transport and installation of offshore foundations to accommodate wind farms for over 10 years.

The new wind farm will consist of 72 four megawatt Siemans turbines with a total maximum installed capacity of 288 megawatts. The expected electricity generation is equivalent to the yearly consumption of approx. 400,000 average German households. Menck GmbH provides a range of specialised 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 harbours.

Menck GmbH has 40 years of industry experience, delivering unprecedented engineering and pile driving knowledge from its tem of highly trained offshore service technicians. MENCKs hydraulic hammers are engineered in Germany near Hamburg and range from 100 to 3500 kJ with comprehensive aftersales support.
