An evaluation on suitability of suction caisson foundation for 5MW offshore wind turbine

5MW급 해상풍력발전시스템용 Suction Caisson 하부구조물 적합성 평가

A three-dimensional numerical modeling using the finite element method for the suction caisson are described to decide suitability as foundation of offshore wind turbine in this paper. In the simulation, soil-structure interaction is defined by comparing experiment data. The reaction of monopod suction caisson is presented by moment loading which was calculated by FAST. Tendency of suction caisson appeared by difference of length and diameter of skirt under coupled loading. Length and diameter of skirt are suggested and evaluated as a offshore wind turbine.
