Nekkar ASA (Nekkar) has been awarded a NOK 21 million grant from Innovation Norway to progress with the development of installation technology that could reduce the cost and environmental footprint associated with wind turbine installations.


The solution – called SkyWalker – uses active heave compensation derived from offshore lifting systems combined with digital solutions that allows for remote controlled and automated solutions.

“Our calculations show that SkyWalker can significantly reduce time, cost and the environmental footprint associated with installation of wind turbines,”
said Preben Liltved, CEO of Oslo-listed Nekkar.


Nekkar is working together with an undisclosed major wind turbine original equipment manufacturer (OEM) and Fred Olsen Renewables, in combination with support from academia, to develop SkyWalker.


The design and technology of SkyWalker enable a controlled lift that can operate heavier loads and reach larger heights than current crane solutions, according to Nekkar. The company also noted that SkyWalker reduces the environmental impact of installing wind turbines by considerably reducing the footprint in nature and CO2 emissions from transportation. SkyWalker is being developed as a zero emissions system.


“SkyWalker is a great example of how we leverage on our strong legacy within oil and gas to create disruptive solutions for sustainable industries. The cooperation with the wind turbine OEM and Fred Olsen Renewables ensures that the development work is fully aligned with the value chain requirements of the wind power industry,”
said Mette Harv, head of the Renewables business area in Nekkar.


“SkyWalker is smaller and requires much less space than other installation solutions such as mobile cranes, meaning that the environmental footprint on terrain is equally reduced. This is for us especially important for onshore wind development on hilly sites in Scandinavia. It is also important for us to create local activity in relation with our wind development projects, which is why we initiated the collaboration and have engaged with the Skywalker project,”
said Gaute Tjensvoll, business developer at Fred. Olsen Renewables.


Another objective of the SkyWalker is to enable installation of wind turbines at locations where it currently is not practically or financially viable to develop wind farms. The technology also allows installation in stronger winds than today and will decrease the total installation time for the wind farm owners.


Nekker stated that later versions of the SkyWalker technology can be applied to installation of both bottom-fixed and floating offshore wind turbines, without having to make adaptations to the turbines.


“We firmly believe that SkyWalker has the potential to become a game-changer for the global wind industry. We are thankful that Innovation Norway and our collaboration partners share this view,”
added Harv.
