Nekkar is currently developing the SkyWalker — A disruptive installation tool based on technology that will significantly reduce the cost and environmental footprint associated with wind turbine installations and major component replacements.

SkyWalker uses active heave compensation derived from offshore lifting systems combined with digital solutions that allow for remote-controlled and automated solutions.

Benefits of skywalker

Reduced wind turbine park installation time

Reduced transport and logistics cost

Increased weather window due to guided and robotic lifting

Lower CO2 emissions

Operates heavier loads and reaches taller heights than current crane solutions

Smaller installation footprint

Operate remotely, unmanned lifting platform

Easier to transport to site

Reduce tower oscillation

Scaled Skywalker model has been tested successfully

Applications & use cases

Offshore major components exchange

Skywalker enables efficient maintenance solutions for offshore turbines. Servicing both floating and bottom-fixed turbines, minimizing the reliance on expensive specialized vessels and eliminating lead time associated with tow-to-shore maintenance.

Discover a cost-effective and reliable option for your offshore operations.  

Installation at port

Streamline the installation process for bottom-fixed WTGs in marshalling harbors with Skywalker. With purpose built and guided lifting capabilities, it ensures smooth and efficient tower section installation.
Skywalker can also support Integration of floating turbines on floaters directly at the quay side, optimizing the installation process. 

Experience a more efficient and cost-effective solution for your offshore turbine projects.

Onshore installation & service

Skywalker offers multiple advantages for onshore wind turbine parks. With faster installation times, reduced transport costs, and increased weather windows for lifting, it outperforms traditional crane solutions. Not only does it operate heavier loads and reach greater heights, but it also minimizes CO2 emissions.

Its compact footprint and remote operation make it convenient to transport and operate on-site.
