OSCILLATION REDUCTION APPARATUS OF MOORING FLOATING BODY AND MOORING FLOATING BODY

摘要

PROBLEM TO BE SOLVED: To provide an oscillation reduction apparatus of the mooring floating body capable of sufficiently reducing even the long cycle oscillation and the mooring floating body.;SOLUTION: It is an oscillation reduction apparatus 2 of the work barge 1 moored in the floating state on the water. It comprises the resistance part 3 suspended from the side part 11 of the work barge into water, the mooring wire 4 one end of which is connected to the resistance part, the rotating body 5 attached to the side part of the work barge and changing the mooring wire direction above the resistance part, the fixed pulley group 6 attached to the side part of the work barge in the position separated from the rotating body, the moveable pulley group 7 arranged below the fixed pulley group and the weight part 8 connected to the moveable pulley group and grounded on the water bottom G. Here, the mooring wire is bridged to the moveable pulley group through the fixed pulley group after changing its direction by the rotating body, is bridged multiple times between the fixed pulley group and moveable pulley group and its end is connected to the fixed pulley group side or the moveable pulley group side.;SELECTED DRAWING: Figure 1;COPYRIGHT: (C)2018,JPO&INPIT
