Fig. 7.7 Current velocity and boom tension during time
Fig. 7.8 Current direction and boom tension during time
The following Fig. 7.8 represents the boom tension at point D and the current
direction at the buoy.
The difference of the boom tension between the two tide directions appears to be
in relation with the sea current direction toward the boom direction. During flooding
tide, the current and the boom directions are almost parallel. As a consequence, the
current inducts very low stress in the curtain. At the contrary, during ebbing tide,
