GBM Works is developing a new method installing offshore wind turbine foundations, or monopiles. We call it: the GBM Vibro-drill. Using our patent pending technology we aim to revolutionize the way that foundations are installed at sea. Conventional installation techniques involve the use of an hydraulic hammer which has the following downsides which are negated by using a GBM Vibro-drill.
- Piling operations using a hydraulic hammer and noise mitigation are complex, time-consuming and therefore prone to delays in bad-weather conditions.
- Each hammer blow creates high noise levels that are harmful to marine life. Several European governments have introduced regulations that result in the mandatory use of expensive noise mitigation such as bubble curtains.
- The impact of the hydraulic hammer on the top of the pile causes severe fatigue damage to the foundation pile, leading to overdesigned, heavy and thus more expensive monopiles.
The GBM Vibro-drill
- The Vibro-drill penetrates the soil faster than impact hammering while also simplifying the installation procedure so that the entire operation can be performed faster and more often.
- Virtually no high noise levels are produced so that marine life is not negatively impacted. Also no additional expensive noise mitigation measures have to be applied during monopile installation.
- Uses vibrations to install the monopile, therefore no large impact is transferred to the pile and therefore no fatigue damage occurs. Therefore, the monopile can be made lighter and less expensive.
We are currently developing our new prototype to further validate the Vibro-drill technology and aim to install our first pilot foundation in 2021.
