"The spatial mooring tensions in sideline mooring systems for waves acting on floating collar were analyzed. In the sideline mooring system, the wave force acting on the floating collar was properly spreaded to the each mooring tension. However, the mooring tension tends to increase in the connecting and mooring ropes depending on the wave and structure conditions. The results are summarized as follows. 1. In the sideline mooring system, the sum of mooring tensions at the rear joint point was more than four times higher than the sum of mooring tensions at the front joint point. 2. The maximum mooring tension was occurred when the wave-steepness(H/L₀) was 0.05 to 0.08 and the relative diameter(B/L₀) was 0.15. 3. At the front joint point, mooring tension develops around the mooring rope connected to the anchor, At the rear joint point, high mooring tension occurred in the bridle and mooring ropes entrained with the direction of incident wave. 4. Although the load distribution is the main function of the bridle rope of the floating collar, more than 10 times of deviation may occur depending on the wave condition. Therefore this must be taken into account in the design." |
