20 monopiles for the Formosa 1 OWF
20 MONOPILES FOR THE FORMOSA 1 OWF
In 2019, the CAPE VLT-320 Triple was used to install 20 tapered monopiles with diameters up to 8.4 meter weighing up to 1,000 tonnes with lengths up to 79 meter, in a water depth of 31 meter for the Formosa I OWF in Taiwan.
The challenging soil conditions at the location posed a risk of pile run or drop fall. This risk was mitigated by the CAPE VLT, as there is a fixed connection between the tool and the pile and load is kept in the crane at all times.
Piles were installed to a safe depth (through pile run risk layers) and driven to final penetration with a large impact hammer.
