Vibrojet®
A silent method for installing offshore wind turbine foundations
Page last modified
January 13 2023
With the advance of 10+ MW wind turbines and increasingly strict noise standards, the existing pile-driving method with hydraulic hammers for monopiles is under high pressure.
Extra measures are needed such as bubble screens or a wall around the monopile. They are expensive and time consuming to install. The pile is also damaged by the hydraulic hammer, which means that larger piles are needed than actually necessary.
GBM Works has developed the Vibrojet®, a machine to install monopiles in a silent and fast way. The Vibrojet® is not only less harmful to marine life and cheaper, the process is also kept strictly under control and requires less power generation.
Pro/con
More silent than impact and vibro hammer
More efficient than impact and vibro hammer
Steel reduction
Easy to scale up
Different from current installation methods
Specification
Areas of Application
Offshore | Nearshore
Vibrating
Vibrating the pile at the tip, avoiding loss of energy through the length of the pile
Installation
Vibrojet installation technology of GBM Works proves to install 2x deeper and 4x faster
Efficiency
Significant reduction in sound emission and fatigue can be expected using the Jet-gun of the Vibrojet
Water injection
Controlled water injection on the inside of a pile, fluidizing the soil resulting in zero resistance
Relative Business Impact
