Next Generation Floating Offshore Wind Turbine Foundation
01.01.1970 News Archive
Floating offshore wind offer a huge potential for the green energy production offshore and the energy transition to zero carbon emission in general. With the development of even larger wind turbines in the range beyond 15 MW, the floating concepts become more attractive and competitive from a cost perspective. However, larger turbines and cost optimization also require a re-thinking of established solution and concepts..
New ideas and innovations are required to further optimize the floating offshore wind farms. In this context, Tractebel Overdick GmbH (OV) developed a new floater concept tailor made to the demands of next generation wind turbines and hence enabling the high potential for large scale offshore wind farms all around the globe.
Versatile and Modular
The new designed floater is following strict design requirements and optimization to reduce the overall costs of the floating foundation, keeping an eye on all major fabrication, installation, and operational aspects. The floater design is load path optimized shape based on triangular arrangement of main load carrying members. No moving parts or wires are used for the floater as this reduces risks and eases the transport and installation operation. The floater is further providing hydrostatic stable floating conditions with the full wind turbine installed on a full range, starting with a minimum draft of 10 m. The final draft and operating condition are achieved by only ballasting the floater. This concept eases maintenance aspects during the operation of the floater, but also creates an extreme flexible basis for quick adjustments regarding the floater hydrostatic stiffness and natural period characteristics of the floating foundation.
The global market for the offshore floating wind has further been considered in the construction and fabrication philosophy. The floater itself can be fabricated without usage of large heavy lift cranes or similar demanding infrastructure which might not be available in remote areas of the world.
The floater is additionally offering sufficient deck and sheltered areas to install modularized add-on packages. This makes the floater also “hydrogen ready”. Hydrogen production modules and exporting equipment can easily be added and compartments of the floater can be used as buffering tanks. Alternative modules such as hydrogen field supply and bunkering or HV export modules may further be considered to make the future floating offshore wind farm more versatile.
