Benefits of WindSpider for Bottom-Fixed wind turbine market

By becoming a part ofthe same structure as the wind turbine, WindSpider solution eliminates the issue of relative motion between the wind turbine and the crane, allowing for installation and major component replacement of bottom-fixed wind turbines from a variety of existing vessels and barges with high availability and competitive day rates. As a result, WindSpider eliminates the need for new jack-up vessels and extends the life of existing jack ups, thus reducing the availability issues, cutting cost, and offering a cost-efficient solution to the JonesAct requirements.

WindSpider’s modular design can be scaled up to perform lifts of over 1500 tonnes, without any height restrictions and requires no design changes to wind turbine or tower, making it a solution for major component replacement and installation of existing and future generations of bottom-fixed turbines.

By carrying outo perations from a floating structure, WindSpider makes the subject of water depth and soil conditions irrelevant and enables development of offshore wind even in areas with earthquake risks. By eliminating the need for interaction with the seabed, WindSpider improves the environmental aspect of the operations, allowing for installation and major component replacement services with no interference with the seabed’s ecosystems.

This means that WindSpider can lift not only higher and heavier, but also greener.
