Organization
Laboratory of Support Structures for Wind Turbines
Laboratory of Support Structures for Wind Turbines strives developing core technologies for towers, substructures, and foundations that support both onshore and offshore wind turbine systems.
Our current research areas are (1) safety improvement of L-type flange joints for wind turbine support structures, (2) development of 3-leg jacket substructures,
(3) structural optimization of monopile substructures, and (4) development of a floater system for offshore wind considering Korean marine and geotechnical conditions.
