Outline of Final Research Achievements |
When a underwater structure is installing, the suspended structure and the crane vessel constitute a pendulum. If the vessel perturbs, the structure swings horizontally and the amplitude depends on the descending speed. To investigate the possibility of controlled installation which suppress swing motion of a suspended structure, we developed a set of experimental system. The experimental system consists of a floating LBL system, a model of structure which has two thrusters. The floating LBL system consists of three buoys each of which has a computer, GPS, and a transponder. We developed a low cost ultrasound ranging system to measure distance between a buoy and the structure.
