<p>The present invention relates to a double brace with a wing shape and a semi-submersible structure having the same. To be more specifically, the double brace can maintain structural strength through an inner brace, can reduce transfer resistance by laying an outer brace while moving, can increase the moving speed and energy efficiency thereof, can reduce an area applied with a wave force by making the outer brace stand while being at a stop, and can minimize influence on heave motion response. In addition, the double brace with a wing shape comprises: an inner brace which connects pontoons or columns in a semi-submersible structure with each other in a horizontal direction; and an outer brace which is installed at the outer side of the inner brace in order to rotate, and has a wing-shaped cross section. The outer brace stands while the semi-submersible structure is at a stop, and is laid during moving.</p> |
