Abstract

Indonesia’s maritime industry has experienced rapid development alongside technological advancements. One of the major challenges is the increasing demand for energy, which has encouraged the development of renewable energy sources. This study aims to analyze the fatigue life of a wind turbine foundation structure installed on a 100-meter Accommodation Work Barge (AWB), with a foundation length of 4.95 meters positioned on the rooftop deck. The analyzed loads consist of four types: turbine load (6082.2 N), wind load (0.000065 MPa), rooftop deck load (0.02306 MPa), and office deck load (0.0035 MPa). The analysis was conducted using ANSYS R1 2021 software with the Simplified Fatigue Assessment method. The results indicate a maximum deformation of 70.06 μm and a maximum stress of 5.5929 MPa. The estimated fatigue life of the turbine foundation is 25.91 years, which satisfies the Det Norske Veritas (DNV) standard requiring a minimum design life of 20 years.
