Abstract
The invention belongs to the sea equipment field and relates to a mooring system used for mooring an offshore floating apparatus based on a plane. The mooring system comprises an anchor chain (2) and an anchor (4) and is characterized by further comprising a plane disc (3), wherein the plane disc (3) is a rigid member formed by section steel welding or bolt connection, and a shape of the plane disc (3) is conjugated with a seabed structure; one end of the anchor chain (2) and the plane disc (3) are connected, the other end of the anchor chain (2) is connected with the moored apparatus; the anchor (4) is located at a lower end of the plane disc (3); according to different loads, the anchor (4) can be a gravity anchor, a dragging embedded anchor, a piled anchor, or a suction anchor or a anchor which is rigidly connected with the plane disc. According to the invention, relative position between the anchor and the chain can be ensured, and mutual winding between the anchor and the chain can be avoided; construction difficulty is substantially reduced; installation cost is reduced; and the mooring system is safer and more reliable.
Description
Technical field:
The invention belongs to Yu Haiyang equipment field, particularly be used for a kind of mooring system of mooring floating marine device based on the plane.
Background technology:
Existing mooring system mainly comprises single point mooring (SPM), spread mooring, inner cupola mooring and outer turret mooring according to being divided by the connection mode of mooring gear and mooring system; But be which kind of mooring mode finally all is to be connected with anchor through hawser or stretched wire, and be fixed in the seabed.Wherein the most frequently used in the offshore sea waters is the structure of catenary, and this structure generally is made up of anchor chain and a plurality of parts of wirerope, and anchor chain and seabed level are joined.This structure need guarantee to exist between the different anchor chains certain angle in work progress; So that make by mooring gear stressed evenly; But reason owing to ocean current; Mutual angle between the anchor chain can't guarantee, even can cause the mutual winding between the anchor chain, so just increased the offshore construction difficulty greatly.
Summary of the invention:
The objective of the invention is to overcome the deficiency of prior art, a kind of mooring system based on the plane is provided, this system can guarantee the relative position relation between the anchor chain accurately, and can avoid the mutual winding between the anchor chain.
The present invention realizes in the following manner:
A kind of mooring system based on the plane comprises anchor chain and anchor; It is characterized in that also comprising planar disk; Planar disk is by shaped steel welding or the bolted connection shape together and the rigid pipe of submarine structure conjugation.Anchor chain one end is connected with planar disk, an end be connected by mooring gear, anchor is positioned at the lower end of planar disk; Anchor according to the difference of load can be for gravity anchor, pull embedded anchor, piled anchor or suction anchor, or the anchor that is rigidly connected with planar disk.
Above-mentioned a kind of mooring system based on the plane is characterized in that: described anchor chain can be connected by the multiple spot of mooring gear and planar disk, after also can being connected the back with the planar disk multiple spot and linking together through a connection piece, again with by a bit being connected on the mooring gear.
Above-mentioned a kind of mooring system based on the plane is characterized in that: described planar disk can be designed to the arbitrary shape with the bottom topography conjugation according to the seabed situation in test marine site.
Beneficial effect of the present invention is following:
1. adopt the connection mode of planar disk can guarantee the relative position relation between the anchor chain accurately, reduced the difficulty of construction greatly, reduced erected cost.
2. adopt anchor chain with by mooring gear multiple spot or single-point ways of connecting, can guarantee to greatest extent by the reliability of mooring gear work.
3. adopt anchor to be positioned at the mounting means of planar disk lower end, in work progress, can strengthen the friction force with the seabed, make mooring system more safe and reliable.
Description of drawings:
Fig. 1: the structural representation of the embodiment of the invention 1
Fig. 2: the structural representation of the embodiment of the invention 2
Fig. 3: the structural representation of the embodiment of the invention 3
Among the figure: 1-is by mooring gear, 2-anchor chain, 3-planar disk, 4-anchor, 5-attaching parts.
The specific embodiment:
Provide three most preferred embodiments of the present invention below in conjunction with accompanying drawing.
Embodiment 1:
As shown in Figure 1, the present invention is a kind of mooring system based on the plane, comprises by mooring gear 1, anchor chain 2, planar disk 3 and anchor 4.When less by the mooring gear volume; Suffered load is less, and sea bed hardness is relatively large, and when allowing by mooring gear bigger rotation to be arranged; Anchor chain 2 one ends can be connected with planar disk 3; One end merges together the back and is connected by mooring gear 1 single-point through attaching parts 5, and the minimum number of anchor chain 2 is three, and its concrete quantity can be according to being decided by the size of mooring gear and construction requirement.Planar disk 3 is by shaped steel welding or bolted connection shape together and the rigid pipe of submarine structure conjugation, is connected with anchor 4 bottom it, and anchor 4 can be according to the different choice gravity anchor of load, pull embedded anchor, piled anchor or suction anchor; During construction, only need with anchor chain 2 respectively with connected direct input by mooring gear 1 and planar disk 3 and get final product to testing the marine site.
Embodiment 2:
As shown in Figure 2; Relatively large by the mooring gear volume, and when not allowing by mooring gear bigger rotation is arranged, an end of anchor chain 2 is connected with planar disk 3 multiple spots; The other end be connected by mooring gear 1 multiple spot; Can reduce like this by mooring gear 1 and the suffered load in anchor chain 2 junctions, the minimum number of anchor chain 2 is three, and concrete quantity and the angle between the anchor chain can be decided according to construction requirement; During construction, get final product to testing the marine site with the planar disk that connects 3, anchor chain 2, anchor 4 with by mooring gear 1 direct input.
Embodiment 3:
As shown in Figure 3, when sea bed was soft relatively in the test marine site, planar disk 3 was rigidly connected with anchor 4, and other are with embodiment 1.
The above; It only is preferred embodiment of the present invention; Be not that technical scope of the present invention is done any restriction, so every foundation technical spirit of the present invention all still belongs in the scope of technical scheme of the present invention any trickle modification, equivalent variations and modification that above embodiment made.
