Silent piling tech destined for Hollandse Kust West windfarm successfully demonstrated

The Vibrojet was designed to reduce noise generated during the installation of monopiles for offshore wind turbines. Using it is also expected to result in deeper, faster pile penetration and reduced costs.

​​The patented technology combines the use of vibratory driving and water injection towards the bottom of the pile. By injecting water, the soil into which the pile is being driven temporarily fluidises. This results in a reduction of inner shaft friction, which makes it easier to vibrate a monopile into the ground

Testing of GBM Works’ Vibrojet technology was completed in March 2025 by a consortium including GBM Works, Atlantic Shores Offshore Wind, CAPE Holland, Deltares, DEME Group, Ecowende, EnBW Energie Baden-Württemberg AG, Eneco, Shell, RWE, Seaway 7, TNO, Van Oord, Vattenfall and Waterkant/Waterekke. The project was also supported by GROW offshore wind and received subsidies from Netherlands Enterprise Agency. 

GBM Works said the tests conducted by the consortium provided valuable data about ‘drivability’ and noise levels, and delivered on the project’s primary objective, demonstrating the technology works in an environment closely resembling that at Hollandse Kust West, where it will be commercially deployed for the first time.

Data from the offshore tests was collected in support of reaching Technology Readiness Level 7.

The Vibrojet technology was tested on board Van Oord’s offshore installation and maintenance vessel, MPI Adventure.
