Driving down monopiles using a contained water mass

Noise Mitigation 2048x2048 2

NOISE REDUCTION

Simulations using finite element modelling show a significant reduction in sound exposure levels as well as sound pressure levels compared to conventional hammers.

ENVIRONMENTALLY SAFE

With EQ-Piling technology, monopiles can be installed safely for marine life without the need for further noise mitigation measures, such as big bubble curtains, in most locations.

FUTURE PROOF

Not limited to a certain anvil or ram weight size, EQ-Piling can cope with even larger monopile diameters and weights in future.

WHAT IS EQ-PILING

Prolonged energy transfer for reduced noise at the source

As the next generation of ‘at the source’ noise mitigation, EQ-Piling leverages decades of experience with conventional impact hammers and near-field noise reduction techniques.

EQ-Piling utilizes a large water tank as a drop weight. This tank, containing up to seventeen hundred tons of seawater, is raised by hydraulic cylinders and released from the drop height setpoint.

The water tank falls onto buffer cylinders which transmit the impact force onto the pile, dampening it to extend the impact time. This impact time is 15 -20 longer than that of conventional piling, resulting in a smooth energy transfer to the monopile and significantly reduced noise levels.

Reduced noise and cost, easier installation

EQ-Piling ensures safe installation for marine life, meeting environmental regulations without additional noise mitigation measures. Simulations using finite element modelling show a significant reduction in sound exposure levels as well as sound pressure levels compared to conventional hammers.

Pile fatigue is reduced by up to 60%, allowing pre-installation of secondary steel fixings. No or less noise mitigation measures means lower foundation & installation project costs, and fewer risks, such as project interruptions, and cuts CO2 emissions and energy consumption by minimizing vessel use. Potential cost reductions include optimizing monopile wall thickness.

EQ-Piling adapts to larger monopile diameters and weights, addressing challenging soil conditions where traditional noise mitigation is less effective. This ensures compliance with underwater noise regulations in diverse environments.

Piling for offshore installations in Europe is restricted by precautionary regulations for underwater noise and its effect on sea life. This limitation during construction increases the cost price. IQIP has found a way for you to enlarge your installation window and reduce costs with innovative technology for effective noise mitigation.
