Effectively reduce noise levels with smooth, silent energy transfer

For over 15 years, IQIP has been at the forefront of innovation and expertise in noise reduction solutions. Based on considerable practical expertise and theoretical knowledge, these ensure environmentally friendly installation. Pile driving for onshore and offshore installations needs to provide the force required to overcome soil resistance while simultaneously reducing noise to meet regulations for airborne and underwater sound levels.

As significant offshore wind growth leads to installation of significantly larger monopile foundations at greater depths, more force is needed. This means more noise – while mitigation legislation is becoming stricter.

IQIP offers proven technology for effective noise mitigation during pile driving, which complies the strictest regulations. We are your trusted partner in laying the foundations for successful projects and a sustainable future.

Offshore Noise Mitigation

Noise Mitigation Systems

Deck Guided

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.

Noise Mitigation Systems

NMS-T-10000

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.

NMS T 10000 Noise Mitigation

PULSE®

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.

Pulse Offshore Noise Mitigation

EQ-Piling

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.

Noise Mitigation challenges and solutions in offshore wind

The strong impulsive noise associated with offshore wind pile driving is potentially harmful to marine life. IQIP always is open to dialogue and happy to work with biologists, regulatory bodies, and developers to ensure ongoing offshore wind farm development in harmony with marine life. Our pile driving procedures and damping systems not only focus on ensuring the smallest possible environmental impact – they also help provide a longer installation window and contribute to cost reduction. By continuously investing in R&D, we maintain our leading position, offering advanced solutions that continue to reduce environmental impact and boost project efficiency and success.

Onshore Noise Mitigation

Noise Reduction System (NRS)

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.

NRS

Onshore PULSE

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.
