FUNDAMENTAL STUDY ON MOORING DESIGN OF ELASTIC MOORING SYSTEM FOR VERY LARGE FLOATING STRUCTURES
Elastic mooring lines can keep stable bearing force even if the position of the attachment point on the floating body side move up and down and it is possible to suppress the motion of the floating structure. But it has never been applied to very large floating structures (VLFS) over 500 m. In addit...

| description | Elastic mooring lines can keep stable bearing force even if the position of the attachment point on the floating body side move up and down and it is possible to suppress the motion of the floating structure. But it has never been applied to very large floating structures (VLFS) over 500 m. In addition, there is no description of mooring design by elastic mooring line in technical standards and guidelines of mooring design. Therefore, in this study, the motion response of VLFS according to the restoring force characteristics of elastic mooring lines was clarified, and a chart showing the mooring specifications within the applicable range of elastic mooring lines was created. Then, the living performance of VLFS was evaluated using the acceleration obtained from the motion response analysis in irregular waves. And a series of procedures up to the determination of mooring specifications were shown in consideration of the safety of the elastic mooring lines and the constant operation. |
