Van Oord has installed three monopile foundations using GBM Works' jetting solution in combination with CAPE’s vibro lifting tool for the first time at commercial scale, a milestone in silent offshore installation.
Designed to reduce underwater noise and minimise impact on marine life, the method was deployed at Ecowende's Hollandse Kust West wind farm using Van Oord's new offshore wind installation vessel Boreas.
GBM Works' VibroJet® technology combines vibrations with controlled water jets inside the monopile to fluidise the soil and reduce resistance.
GBM's in-depth understanding of how water jets interact with different soil conditions allowed for precise operational control, guided by the purpose-built Fluidflow® prediction model.
The technology has demonstrated strong potential in the dense sand layers typical of the Dutch North Sea.
Jan Willem Elleswijk, Project Director at Van Oord, said: “The successful execution demonstrates that large-scale silent installation technologies are maturing rapidly. We are pleased to have applied this innovation as part of the full foundation installation scope at Hollandse Kust West, where all 52 monopiles were installed using our vessel Boreas, once again demonstrating the vessel’s outstanding capabilities.”
The VibroJet® installations were carried out in combination with CAPE Holland's Vibro Technology, which uses vertical vibrations to
