IQIP, the foundation and installation specialist with headquarters in Sliedrecht, the Netherlands, has put their newly developed piling technique EQ-Piling in action. The innovative piling technique enables noise-compliant installation of even the largest monopiles.
Conventional impact piling has long been a proven and unparalleled method for installing large monopile foundations at the required depths. However, it comes with a significant drawback: the noise generated during the process can be harmful to marine life. The challenge we faced was to deliver the necessary force to overcome soil resistance while significantly reducing noise levels.
Pushing force
EQ-Piling successfully meets this challenge by employing a newly developed technique featuring a substantially prolonged impact force characteristic. This method uses the impact of a falling mass, in this case, contained water, over an extended period, resulting in an exceptionally smooth energy transfer to the pile. Unlike conventional methods that rely on impact force, EQ-Piling generates a pushing force.
This technology ensures that developers, governments, and contractors can now work in full compliance with environmental regulations. EQ-Piling offers numerous advantages, including noise reduction without the need for additional mitigation measures, lower project costs, decreased carbon emissions, and enhanced efficiency.
