Minimise sound exposure according to the strictest regulations
Reduce pile driving noise levels and operational time, boost accuracy, and create a safer working environment. This integrated system provides a longer installation window which significantly contributes to cost reduction by supporting monopile inclination and rotation and safeguarding against the impact of waves and currents.
The world’s largest noise mitigation system at a staggering 50-meter height, a 45-meter-wide template base, a total weight just under 2,500 tons, and the capability to handle monopiles up to 10.0 meters across. The NMS-T-10000 can be used from a floating vessel and can keep monopiles vertical, rotating them to the correct heading. Its integrated template has a levelling system to ensure alignment and stability.
Reduce noise levels significantly at source. A damping system (hammer add-on) positioned between the hammer and sleeve can be used with IQIP’s existing hammers. Enhanced efficiency enables smooth, silent energy transfer over longer impact duration whenever possible. Short, intense energy transmission with high peak force is only applied when soil conditions are particularly challenging.
Our highly innovative approach to pile driving applies deceleration of a vast water tank to deliver a long-duration blow to the pile. This new technology makes noise-compliant next-generation monopile installation possible. EQ-Piling offers numerous advantages, such as noise reduction, no additional mitigation measures, lower costs, decreased carbon emissions, and greater efficiency.
With NRS, there is no need to introduce temporary noise barriers or time slots during pile driving. The NRS covers hammer impact area as well as the total pile length, for a safe noise level of 80 dB(A) at a distance of 20 m from the hammer – as opposed to a distance of 100 m from the hammer without NRS. This enables safe pile driving in urban areas.
Ensure safe working and minimize damage due to noise pollution when pile driving. This Hydrohammer® add-on is positioned between the pile driving hammer and sleeve and damps impact and noise with two hydraulic plungers. The volume in between the plungers can be filled with water. This controls the impact characteristic, reducing noise at source.
