Floating Wind Farms and Mooring / Anchor Types

Do you think the future of offshore wind will go in one direction or the other (floating vs. non-floating), or will it be a situation where the specific technology is chosen based on the site, geography, needs, etc.?

Currently, floating structures are designed for locations where fixed structures are economically unviable (deep waters, or shallow waters with bad seabed quality).

But when you have a location where both fixed and floating structures are equally vialbe there will be other factors in place like:

  • Costs of construction (substructures)
  • Costs of transportation
  • Cost of installation (fixed wind farms require the use of heavy lift vessels for the installation of the foundations and then again for the installation of the turbines whilst the floating foundations can be completely built in a drydock and the turbines can be installed with a shore crane which eliminates risks of installation offshore)
    • The costs and the availability of both methods need to be benchmarked

So I don't neceserilly thinkt it will come to fixed vs floating, the installation costs at the specific geographic location need to be outweighed.

Makes sense-- as they say, no need for a silver bullet when we have an entire toolbox of solutions to deploy!
