Abstract

 Japan's energy policy has been changed after the Great East Japan Earthquake. Marine renewable energy is increasing. An advantage of tidal current energies is hardly influenced by weather conditions. Energy can be generated both day and night. During the installation work of tidal power generation device, the vessel and the suspended load are moving by the waves and tidal currents. As a result, the installation accuracy of the suspended load is reduced. Therefore, it is important to understand the motion characteristics of the vessel and the suspended load. This study examined the characteristics of movement during installation of tidal power generation device using a crane vessel in the hydraulic model experiment.
