Tetrahedron creating new crane for offshore wind

Tetrahedron engineers are putting a lot of effort into creating a special, cutting-edge kind of crane for the offshore wind business.

As wind turbines grow in size, we needed a new kind of crane with a new installation method, which is how Wilco Stavenuiter, Director of Rotterdam-based Tetrahedron, came up with the concept for a super crane. The shape, which is a tetrahedron with a triangle base, holds the secret.

In order to install the most recent offshore wind turbines, the crane will be able to extend up to 130 meters.

“The unique thing about our crane is that we have moved the pivot point from the bottom to the top. What makes it so special is that it does not need more lateral reach; instead, it can reach much higher. That extra height is exactly what the offshore wind industry needs, as wind turbines are getting taller and taller,” Wilco explained.

The business will assemble a crane prototype along with a group of investors. The crane will be erected in the Netherlands as well as having all of its components built in the country. By 2024, the prototype is anticipated to be completed.

Logical decision

Rotterdam was a logical choice for Wilco and his company. “With Delft University of Technology nearby and the neighbouring Rotterdam University of Applied Sciences, there is a lot of interest from people who want to work for us. In addition, Rotterdam has a network of suppliers able to help construct such a large crane. And finally, it is imperative that we are here because the port can accommodate the huge wind installation vessels onto which the crane will be fitted.”
