Transient Translational–Rotational Motion of an Ocean Current Converter Mooring System with Initial Conditions

Systems of ocean current power generation are generally moored deep in the seabed. The mooring system is like ropes. ropes very long and can provide tension but not compression, their dynamic displacement large unstable, which different from traditional structures. To generate high-efficiency generation, it necessary to design a stable system. Maintaining stability small invertor significantly helpful for high efficiency invertor. In addition, tension, safety factor, life essential. this study, we investigate transient behavior composed an inverter platform, pontoon, under initial conditions. An analytical method proposed. translational rotational displacements 36 independent normalized fundamental solutions. composition depends on Each solution derived by using Frobenius method. This study proposes replacement single-rope mode with double-rope parallel mode, maintain fracture strength low effective spring constant rope. It verified that decrease instantaneous increase factor Additionally, hydrodynamic damping coefficients
