OFFSHORE CONSTRUCTION FOR TIDAL STREAM POWER GENERATION AND CONSTRUCTION METHOD THEREFOR AND TIDAL STREAM POWER GENERATION SYSTEM USING THE SAME

摘要

The present invention relates to an offshore structure for tidal power generation, a method for constructing the same, and a tidal power generation system using the same and, more specifically, to an offshore structure for tidal power generation, a method for constructing the same, and a tidal power generation system using the same, wherein: a lock bolt anchor is used to form columns on an underwater rock layer in a region in which a water flow is fast due to the tidal current, thereby facilitating the construction of the offshore structure; and a power generator unit having a height that varies according to the sea level is used to enable an increase in power generation efficiency. To this end, the tidal power generation system is configured to be supported by the offshore structure and include the power generator unit, and the offshore structure for the tidal power generation is constructed by performing at least a foundation construction step and an offshore structure construction step.
