Siemens Gamesa SG 11.0-200 DD

As the largest offshore wind farm in Scotland at first power, Seagreen Alpha required 456 tower flange sets across a 15-month delivery programme. Torque deployed a dedicated cell of three CNC horizontal borers for the duration, achieving a production rate of 32 flanges per week. Post-commissioning, the SSE Renewables operations team reported zero structural non-conformances. The project established Torque's reputation for large-series tower internal supply.
