Solutions for energy and connectivity challenges

During the installation and commissioning phase we provide specialist niche expertise for some of the most technically challenging scopes. These are areas that we have grown our expertise including work pack methodology, safe systems, and broader technical excellence. This means we execute work scopes safely, we mitigate project risk, and save you time and save money.

Services for offshore wind during installation and commissioning include:

  • Noise attenuation
  • Cable management
  • Testing and terminations

Noise attenuation

To protect marine life during EOD and piling operations, JFR operate the world’s largest fleet* of rapid deployment specialist air compressors for Bubble Curtain applications.

In operation, ‘class zero’ air is delivered to a flexible piping with formed nozzle openings installed on the seabed surrounding the ongoing operations e.g. foundation monopiles.

The resultant bubble curtain alters the form of pressure waves, changing them from brief percussive bangs to longer, weaker waves, where the changed characteristic lessens harm to marine life.
