Abstract
This paper deals with the reliability analysis of mono-pile foundation for an offshore wind turbine (OWT). Reliability analyses of mono-pile foundation for an NREL 5.0 MW wind offshore turbine were performed to investigate the uncertainty and sensitivity of design parameters. Soil profile and the uncertainties of soil parameters were determined using geotechnical investigation at the test-bed in West-South coasts of Buan-Yeongkwang in Yellow Sea of Korea. First order reliability method with the response surface method (RSM-FORM) and the Monte Carlo simulation technique were used to the analyses. The pile analyses were also carried out by modeling a laterally loaded pile as a vertical beam supported by a series of discrete springs, each of which has its own nonlinear load-displacement characteristics.nd sensitivity of design parameters.
