Sevan형 1MW OTEC 구조물의 운동응답에 대한 모형시험 연구

Abstract

Sevan 1MW OTEC(Ocean Thermal Energy Conversion) platform was designed to apply in equator seas. In this study, OTEC platform was investigated by experimental methods. The OTEC platform that is octagon-shaped(Sevan) was carried out in Ocean Engineering Basin of KRISO. This experiments were performed for a various tests of the regular wave and irregular wave. The responses of the platform in regular waves had a good agreement between numerical and experimental results such as motion RAOs. The peak period of heave and pitch motions were observed around 0.5rad/s. The standard deviation(STD) of platform motion was checked in irregular waves of equator and hawaii seas. The STD of pitch was less than 4° of operability requirement in equator conditions and the surge STD of wave frequency had good agreement between numerical and experimental results.Engineering Basin of KRISO.
