Embodiment Construction

[0015] The present invention will be described in detail below in conjunction with the accompanying drawings, and the same reference numerals represent the same components.

[0016] figure 2 It is a three-dimensional sectional view of the underwater hose float provided by the present invention. Such as figure 2 As shown, the underwater hose buoy in the buoy member 1 of the single point mooring system provided by the present invention includes a left half buoy 12, a right half buoy 11 and an internal clip 14, wherein the left half buoy is arranged axially There is a semi-cylindrical through hole; the right half-float 11 is completely mirror-symmetrical to the left half-float, and the right half-float 11 is also provided with a semi-cylindrical through-hole 16 along the axial direction; In the cylindrical through hole formed by the semicylindrical through hole of the left half float and the semicylindrical through hole of the right half float. A semi-circular groove is prov...

Abstract

The invention provides an underwater hose floating block in a buoy element (1) of a single point mooring system, and belongs to the technical field of marine construction structural elements. The underwater hose floating block comprises a left half floating block (12), a right half floating block (11) and an inner clip (14), wherein a half-cylindrical through hole is axially formed in the left half floating block (12); the right half floating block (11) and the left half floating block (12) are in mirror symmetry; another half-cylindrical through hole is axially formed in the right half floating block (11); the half-cylindrical through holes form a cylindrical through hole; the inner clip (14) is annular, and is arranged in the cylindrical through hole. The underwater hose floating block can not only provide normal buoyant force, but also rotate with the flowing direction of water, obviously reduce water flow resistance on the underwater hose floating block, and effectively suppress water flow vortex-induced vibration of an underwater hose element, so as to improve the underwater stability of the underwater hose element.

Description

technical field [0001] The invention relates to an underwater hose floating block of a single-point mooring system, which belongs to the technical field of marine building structural components. Background technique [0002] A single point mooring (SPM) system refers to a moored ship that rotates freely around a single mooring point around a single mooring point as the wind and current change, so that it is constantly in the wind, wave, current and minimum force location of the mooring system. figure 1 is a schematic diagram of the composition of the single point mooring system, such as figure 1 As shown, the single point mooring system is mainly composed of a buoy component 1 , an anchor chain component 2 , a mooring line component 3 , a floating hose component 4 and an underwater hose component 5 . The buoy components are connected to anchors or piles on the seabed by six radially arranged anchor chains, and the buoy components and the subsea manifold are connected by un...
