1 MW 조류발전기 O&M 위험성평가 사례 연구

Tidal power is a technology that generates electricity by utilizing tidal current energy, and in recent years, with the advancement of technology, it has reached the stage of real sea performance test. However, in the case of Korea, there is a lack of construction experience and equipment, and work in fast flows such as the Uldolmok region involves various risk factors. In order to establish measures to reduce these risk factors, Korea’s Occupational Safety and Health Act recommends performing a risk assessment to identify and manage risk factors that may occur during work in advance. Risk assessment is a process aimed at identifying and evaluating potential risk factors that may arise during work, with the goal of minimizing losses caused by accidents. Therefore, in this study, a risk assessment was conducted to identify risk factors that may occur during offshore O&M work of the 1 MW tidal current energy converter and to ensure the safety of workers and the environment. A total of 60 risk factors were identified, including marine and weather conditions, equipment and personnel, and work environments, and a qualitative risk assessment was conducted three times based on the judgment of several field experts.
