부유식 재생에너지 플랜트의 개념설계를 통한 계류라인의 피로설계 = A Fatigue Design of Mooring Lines and A Concept Design of Floating-Type Combined Renewable Energy Plant

다국어 초록 (Multilingual Abstract)

This paper presents the concept design precedure of floating-type combined renewable energy platform based on hydrodynamic analyses and the fatigue design procedure of taut-type mooring lines. Two types of combined renewable energy platforms are taken into account: first combination of wind, wave, and photovoltanic energies and second combination of wind , current, photovoltanic energies. The concept design is from the literature survey, but main dimensions have been decided based on the basic hydrostatic calculation. Fully coupled hydrodynamic analyses have been carried out to identify motion characteristics of the floating body and tension histories of each mooring lines. Further fatigue lives using rainflow cycle counting method, API stress-life diagram, and Palmgren-Miner rule are predicted for chain link-type taut mooring system. Finally mooring lines satisfying design life of twenty years are proposed.
