Various optimists are proposing floating offshore wind turbines. They obviously get around the NIMBY problem of inshore wind turbines, and should have better access to wind. But https://www.boem.gov/sites/default/...024_1021_CA_PEIS_Vol_II_Appendices_508c_0.pdf includes a pretty good survey of the design of such things in the first 35 pages.

The discussion of the mooring cables ploughing up big areas of the seabed is good. Anyway lots of numbers and pretty pictures, it's a great science project proposal. It doesn't sound like an implemetation ready solution. Just a reminder, 3 of these turbines would produce more energy than the current global fleet of floating offshore wind even it it was working which most of it isn't at the moment, it is being fixed back at port.

Why can't they use dynamic position to hold the turbine in place like semi-submersible oil rigs? 😉
