The influence of mooring systems with lines of different material on the dynamic response of a floating wind turbine is studied using a 5 MW OC4-DeepCwind semi-submersible wind turbine as a representative prototype in this study. Two types of mooring systems were designed using the MoorDyn module in OpenFAST software (v3. 1. https://www.ngetikin.com/quick-offer-1-Gallon-Universal-Primer-Pro-Deep-Penetrating-Primer-big-deal/
