CAPE Holland has been awarded the contract by Seaway 7 to supply a Vibro Lifting Tool (VLT) for the installation of the monopile foundations for Kaskasi OWF.
After a number of years of development and many successful installations, this will be the first offshore wind project whereby the monopiles will be driven to final penetration with a vibro hammer only.
No stranger to the vibro piling technology, Seaway 7 has already been using the CAPE vibro equipment back in 2012 for the first time to drive the monopiles for the Riffgat project to stabile depth. Since then they used the vibro equipment on a number of Oil and Gas projects and last year also on an OWF project in Taiwan.
With the unique capabilities of being a certified offshore lifting tool with the ability of upending and driving the piles quickly with reduced noise emissions, it is set to be a gamechanger in the Offshore Wind industry.
The Vibro Lifting Tool for this project will have multiple vibro hammers linked together to provide a total of 1920 kgm which makes this the most powerful vibro pile driver in the world. A specially developed clamping system will be used to create the interface between the Vibro Lifting Tool and the flanged top of the monopiles.
CAPE Holland CEO Laurens de Neef commented: ”We have always believed to be able to provide an installation tool which can significantly reduce overall costs of the installation of monopiles for offshore wind farms and we’re very happy that all our hard work over the previous years is now paying off and creating the opportunity for us to prove this. We like to thank both Seaway 7 and innogy for their support of the vibro technology and we are looking forward to further building on this relationship.”
