Being able to prop up wind turbines onshore while reducing its carbon footprint is a major goal for Vattenfall. For this reason, the company partnered up with heavy lifting specialist Mammoet to develop an innovative solution that could unlock benefits for both the environment and local communities in the years ahead.

The companies came up with a climbing crane concept that uses the turbine tower instead of the ground for support as it adds more sections in stages, with no limit on how high it can go. Although it is still on the drawing board, progress to date has been encouraging and a Vattenfall team from its Business Unit Onshore Wind is now working with experts from Mammoet to take the development of their concept forward with hopes the new technology could be seen on sites within the next few years.

For Program Manager Jelmer Boukes and his team at Vattenfall, it would represent one of the biggest step-changes seen in wind farm construction for years, offering multiple benefits in terms of CO2 reduction, minimised impact on local communities and cost benefits. “The climbing crane would be much smaller and easier to get to site, as well as to move to another location when it has completed a turbine,” Boukes says.

Boukes adds that with less civil infrastructure, noise and disruption for the local community would be minimised. Also, the climbing crane would be able to reach greater heights and operate in locations with up to 80 percent more wind, unlocking new complex and remote wind farm sites.

Vattenfall targeting CO2 reduction

The reduction in transport activity around the building site due to the new crane, would reduce the carbon footprint of construction and impact on the local community.

There would also be direct benefits in the operation of the crane itself. Due to its much smaller engine and capacity requirement, the crane could be powered by electricity instead of fossil fuels.

Commenting on the new design, Eva Julius-Philipp, Head of Environment and Sustainability Wind, said, “In total it is estimated that the new crane could significantly reduce transport and installation emissions during wind farm construction compared to standard methods. It will help us take another important step towards Vattenfall’s goal of net zero emissions by 2040 for our operations.”
