A motion reduction apparatus has an orthorhombic shaped floating main body (), a plumb plate supported vertically on one side section of the floating main body by stay members (), and flow sections () for flooding with incoming water are provided between the floating main body and the plumb plate in such a way that an upper end section of the plumb plate is at about the same height as the bottom surface of the floating main body.

Motion reduction apparatus and floating body therewith

A motion reduced floating structure includes a main hull structure and a wave damping structure connected with the main hull structure. The wave damping structure may include a back board, a lower horizontal board and vertical members. The back board is connected with the main hull structure, and the lower horizontal board is connected with a lower portion of the back board to extend in a horizontal direction and is under a seawater surface in case of mooring. The vertical members are connected with the lower horizontal board and the back board. A vertical direction hole is provided for the lower horizontal board.

Motion reduced floating structure

The motion reducing apparatus has an orthorhombic shaped floating main body, a horizontal plumb plate supported horizontally on one side section of the floating main body by stay members, and flow sections for flooding with incoming water are provided between the floating main body and the horizontal plate in such a way that the horizontal plate is at about the same height as the bottom surface of the floating main body.
