Monopile decommissioning demonstration
MONOPILE DECOMMISSIONING DEMONSTRATION IN THE NETHERLANDS
In 2016, the CAPE VLT-320 was used to decommission a monopile with a slip joint connection with a length of 27 meter, weighting 127 ton with a bottom diameter of 4 meter at the Maasvlakte 2 in the Netherlands.
The pile was installed 7 months prior to extraction using the same equipment. The pile served as a foundation for a demonstration turbine.
The monopile was extracted in record time of 11 minutes after which it was down-ended easily, ready to be picked up and transported to the SIF factory to be extended for installation offshore for the next phase in the demonstration project called the Slip Joint Offshore Research project (SJOR).
