Global operational floating capacity was about 278 MW at the end of 2025 (GWEC 2026) with roughly 109 MW more operational in 2026 (RenewableUK, https://www.energyglobal.com/wind/07102026/new-renewableuk-report-shows-38-increase-in-global-operational-floating-offshore-wind-capacity/amp/), about 0.08% of the target. The largest farm, Hywind Tampen (88 MW, about 140 km offshore in 260-300 m of water, https://en.wikipedia.org/wiki/Hywind_Tampen), shows the concept works. Open design tools exist (NREL/NLR WEIS with RAFT and OpenFAST, https://github.com/nlrwindsystems/weis), but the unsolved problem is cost: floating LCOE remains several times fixed-bottom and 2025-2026 saw cancellations and halts (TwinHub CfD cancelled, Trollvind halted, https://www.rechargenews.com/floating-wind/the-floating-wind-revolution-is-delayed-heres-why/2-1-2001008). Honest limit: floating platforms, moorings and the design toolchain are prior art; tasks must target unsolved cost, mooring, installation or far-shore transmission problems with their own prior-art basis, not re-deriving Hywind-class designs.
