  7. Abstract:
  8. For the stability of floating solar PV power plants against environmental forces and the safety of operators during maintenance and repair, the mooring system ought to be designed based on the position of the plant, the size of the plant, and weather conditions. Floating solar PV power plants are mostly located in reservoirs with significant water level variations, or in some cases in inland seas where changes in water level are the most important challenge in their mooring system. In this project, different methods to overcome the water level variations have been studied and finally, a creative idea which covers the weaknesses of previous ones has been represented. By using programming language Python in connection with the OrcaFlex Application Programming Interface (API), the mooring system of a floating solar PV power plant with a capacity of 50kW has been programmed. The mooring system has been designed to withstand environmental loads at a minimum depth of 50m and a maximum depth of 60m. Based on recommendations of DNVGL, the mooring system has been simulated in different load cases (intact and failure mooring system modes) for a one-year and fifty-year return period. Following this, the forces in mooring lines and horizontal displacement in Ultimate Limit State (ULS) and Accidental Limit State (ALS) for the maximum and minimum depths have been extracted from OrcaFlex. Analysing the system in defined load cases, the critical force in ULS and ALS both happened in 60m depth of the fifty-year return period. In addition to that, the maximum displacement of the plant was 6.35m in the failure mode with maximum depth and 50-year return period. Finally, the primary assumptions were modified and the optimized mooring system was represented
