Offshore wind turbines harness wind power to produce electricity, representing a crucial renewable energy source in the offshore environment. Within these environments, wind and waves impose cyclic loads on the turbines. The ocean floor's uneven terrain results in varying degrees of slope. Monopiles are large hollow rigid steel structures that are easy to transport and install and are more cost-effective. The rigidity is because the pile diameter usually ranges from 3–8 m. Using PLAXIS 3D Finite Element Software, this study simulates the behavior of monopiles under real-world conditions by adjusting pile positions (c = 0Dp, 2.5Dp, 5Dp, 7.5Dp) on sloping ground profiles (Flat, 1 V:5H, 1 V: 2.5H) and subjecting them to one-way cyclic loading. Soil density was maintained at 55% relative density to investigate how soil–pile stiffness affects lateral load capacity. Maintaining an e/Dp (Eccentricity to diameter) ratio of 12 and a load amplitude of 50% simulates realistic loading conditions. The HS-Small soil model accurately captures stiffness behavior. Results, including load vs. displacement, stiffness, and accumulated displacement vs. cycle number, highlight the performance of piles on flat versus sloping ground. Piles positioned on slopes exhibit decreased stiffness and increased displacement with the increase in cycles.
