Its automated reviewer stops only when capacity, steel intensity, unit cost, constructability and fatigue scores clear stated floors. The top floating-wind support design passed China Classification Society Approval in Principle and used 8.1 percent less steel and 8.1 percent lower unit capital cost than the human-optimized TuQiang baseline. Approval in Principle is an external design-stage check, not final construction certification, and the authors list detailed design and fabrication constraints as remaining work.",
