Title:
SEA BOTTOM FOUNDATION AND MOORING ROPE USED FOR TIDAL CURRENT POWER GENERATION
Document Type and Number:
Japanese Patent JP2016074395
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a technology of a sea bottom foundation suitable for such a load condition, though large pull-up force is added to the foundation of the sea bottom as its reaction force, when a hull sinks in by receiving large thrust received from a tidal current to a mooring rope in power generation time, in a mooring type tidal current power generation ship.SOLUTION: A mooring system is provided so that in the case of a small load, a pile is provided at the sea bottom so as to become a right angle to the extending direction of a mooring rope 4, and in the case of a large load, a sea bottom foundation for burying a foundation structure is provided at the sea bottom, and a relay buoy 5 is provided near a power generation ship 6 on the mooring rope, and in operation time, the mooring rope on the side of the power generation ship 6 side is connected to the relay buoy 5, and when the power generation ship 6 leaves from a site, the mooring rope of one's own ship is released from the relay buoy 5, and the relay buoy 5 floats on the sea. By this operation system, work in the sea is wholly eliminated except for burying type sea bottom foundation construction time, and work necessary for normal operation time can be wholly executed on the sea, and a tidal current power generation development can be accelerated.SELECTED DRAWING: Figure 1
