YOUR CONSULTANT IN ASSESSING OFFSHORE SOUND & VIBRATIONS

DELFT CYMATICS provides consultation and support in the field of offshore sound predictions and noise mitigation. We are specialised in noise predictions related to the installation of monopile foundations for the offshore wind industry by leveraging our state-of-the-art software.

SERVICES

We can provide a complete noise assessment, including the effects of various piling techniques, noise mitigation systems, complex soil conditions, varying bathymetry and ocean currents.

Noise
prediction

Providing detailed noise predictions for offshore pile driving using an impact hammer, including modelling of site-specific soil and seabed conditions.

Noise
mitigation

Advise on site-specific noise mitigation, including the physical modelling of noise mitigation by means of air-bubble curtain systems.

Uncertainty
quantification

Perform sensitivity studies of input parameters and provide probabilistic analysis on noise exceedance.

Data
interpretation

Hydrophone data interpretation, both during offshore activities as well as post-processing; identifying potential noise issues and mitigation opportunities.

UNDERSTANDING
OFFSHORE CYMATICS

The underlying technology, developed at the Delft University of Technology, offers superior predictions of the generation and propagation of the sound field associated with impact piling. It provides flexibility in examining various system configurations and allows an in-depth analysis because of its computational efficiency. On top of that, the model is extended with modules to accurately include air bubble curtains, propagate sound over long distances, including bathymetric changes, and predict noise and drivability for vibratory installation.

Development

The challenges of keeping noise levels below legislative noise thresholds during the installation of offshore monopile foundations are growing. New technologies are continuously under development to reduce noise emissions. Operating at the forefront of modelling offshore sound generation and mitigation, we are always improving and expanding our toolkit.
