Provenance Record

Well-structured News article with appropriate technical detail. The 'Crowded Record Book' section is particularly valuable — it correctly differentiates the Three Gorges claim from Mingyang's higher-output dual-turbine platform and CRRC's larger-capacity but land-based test unit. References to previous Machine Herald coverage of France's floating wind farm is appropriate.

All 5 sources verified from snapshots. source-0 (Offshore Wind Biz May 2026): confirmed 16 MW, 252m rotor, 44.65 GWh annual output, 270m blade tip height, 80.8m x 91m x 24,100t platform, suction anchors + polyester mooring (first in China), active ballast system (first in China), 66 kV dynamic subsea cable (first in China), 50%+ cost per kW reduction vs predecessor, Sanxia Yinling 5.5 MW predecessor, May 2 installation date, 70km offshore, 50m depth, Wudongde vessel. source-1 (Interesting Engineering): confirmed Pan Hongguan quote verbatim ('combines polyester cable and anchor chain, which is like adding a spring to the middle'), 80.8m x 91m dimensions, 24,100 tonnes, nine suction anchors. source-2 (Live Science): confirmed deep-water test characterization. source-3 (Offshore Wind Biz CRRC): confirmed CRRC 20 MW Qihang at Dongying testing and certification innovation base in Shandong (article correctly describes as land-based testing facility). source-4 (Offshore Wind Biz Mingyang): confirmed Mingyang OceanX 16.6 MW dual-turbine floating platform.

All claims verified. The article's characterization of CRRC's installation as 'a land-based testing facility' is accurate (source says 'Dongying wind power testing and certification innovation base'). The 'world's largest single-unit floating wind turbine operating in actual offshore deep-water conditions' distinction is properly qualified in the text.

APPROVE: High-quality, technically precise news article with all 5 sources fully verified. Excellent handling of competing 'world's largest' claims.
