Specifically, both the top angle mooring 41 and the intermediate mooring 42 employ steel cables.
Specifically, each pontoon 102 at the top angle is respectively connected with one anchor chain, and the pontoons 102 at two adjacent sides share one anchor chain in a Y-shaped connection mode, so that eight anchor chains in total are uniformly positioned at the corner points and the side midpoints of the integral deck.
Compared with a common four-anchor-chain system with a top angle, the anchor-chain system in the invention realizes eight-directional segmentation on a horizontal plane, improves the anisotropy of the mooring system to the wave direction, namely eight anchor chains can be uniformly stressed in any wave downwards, and serious stress non-uniformity phenomenon in oblique incidence in the four-anchor-chain system can not occur.
Finally, it should be noted that: the above embodiments are only for illustrating the technical solution of the present invention, and are not limiting; although the invention has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical scheme described in the foregoing embodiments can be modified or some technical features thereof can be replaced by equivalents; such modifications and substitutions do not depart from the spirit and scope of the technical solutions of the embodiments of the present invention.
