Abstract
The utility model discloses a hypostyle SPAR platform mooring cable arrangement structure. A mooring cable (2) is connected with a peripheral column (4) of a hypostyle SPAR platform hard cabin (1) through a cable chock (3). The hypostyle SPAR platform mooring cable arrangement structure is characterized by being composed of four groups of mooring cables (2), each two adjacent groups of mooring cables (2) have an interval of 90 DEG, and the adjacent mooring cables (2) in each group have an interval of 5 DEG; the mooring cables (2) are respectively arranged on the outer surface of the peripheral column (4), the number and the specification of the mooring cables (2) in each group are determined through calculation, and the other end of the mooring cable (2) is connected with seabed anchoring foundation. Each mooring cable (2) consists of an upper end anchor chain (5), a middle end anchor chain (6) and a lower end anchor chain (7). The arrangement structure is suitable for the hypostyle SPAR platform with eight peripheral columns. Meanwhile, the structure has good withstand effect to wave and current in any direction.
Description
Technical field
The utility model relates to a kind of arrangement structure of polystyle SPAR platform mooring line, particularly has the polystyle SPAR platform of eight peripheral cylinders.
Background technology
The SPAR platform is a kind of of offshore platform, and it is applicable to from 300 meters deep-seas to 3000 meters of the depth of waters of the depth of water, can exploit the work of aspects such as oil gas, drilling and repairing well.Part between the bottom is called hard cabin to the SPAR main platform body from the main body flying deck to variable ballast tank.The SPAR platform has multiple pattern, the SPAR platform can be divided into two big classes according to its hard cabin pattern, and a class is open side type SPAR, and its hard cabin part is made up of single cylinder; Another kind of is polystyle SPAR, and its hard cabin part is made up of some cylinders than minor diameter.Polystyle SPAR periphery has six or eight isodiametric cylinders.
The SPAR platform for reducing the displacement of platform under effects such as stormy waves stream, needs to arrange mooring line usually when marine work.The layout of mooring line is relevant with platform hard cabin pattern, and the mooring line arrangement structure that the polystyle platform is commonly used has two kinds at present, respectively corresponding two kinds of different platform hard cabin structures:
The one, the platform hard cabin is surrounded by six isodiametric cylinders, arranges a mooring line between per two adjacent cylinders, altogether the six roots of sensation.This arrangement can reduce the disturbance of mooring line to the current that flow through periphery, but because the mooring line radical is less, needs higher mooring line specification.
The 2nd, the platform hard cabin is surrounded by a central cylindrical and six isodiametric peripheral cylinders, arranges mooring line at peripheral cylindrical outer surface, arranges three groups altogether, is separated by 120 ° between every group, three mooring lines is arranged, 5 ° at interval of adjacent mooring lines in every group.This arrangement only is applicable to the pattern of six peripheral cylinders, is not suitable for the pattern of eight peripheral cylinders.
The utility model content
The purpose of this utility model is to design a kind of polystyle SPAR platform mooring line arrangement structure with eight peripheral cylinders that is applicable at the deficiency of existing polystyle SPAR platform mooring line arrangement structure.The utility model is characterised in that the mooring line layout is made of four groups of mooring lines, the interval is 90 ° between the two adjacent groups mooring line, be spaced apart 5 ° in every group between the adjacent mooring line, mooring line is arranged in the outside face of peripheral cylinder, the radical of mooring line, specification determine that by calculating the mooring line other end links to each other with the seabed anchor foundation in every group.
The outside face of the peripheral cylinder of described polystyle SPAR flat-bed is provided with mooring pipe, is used to connect mooring line.
Described mooring line is made up of three parts, is respectively that upper end anchor chain, middle-end connect, the lower end anchor chain.Wherein the middle-end connection can adopt wirerope also can adopt the polyester cable.The length of upper end anchor chain will guarantee that the middle-end connection can not touch the SPAR main platform body, and the length of lower end anchor chain will guarantee that the middle-end connection can not touch the seabed.
The point of connection of the peripheral cylinder of described mooring line and polystyle SPAR platform all is in the sustained height place.
A kind of polystyle SPAR platform mooring line arrangement structure of the present utility model is suitable for and has the platform in the polystyle SPAR of eight peripheral cylinders, can select only mooring line radical and specification by calculating, and reach the effect that reduces cost.Simultaneously the utility model all has the stormy waves stream of any direction and well resists effect, is specially adapted to the marine site that environmental data lacks.
Description of drawings
Fig. 1 is the utility model side schematic view.
Fig. 2 is the front elevation of Fig. 1.
Fig. 3 is a structural representation of the present utility model.
Among the figure: 1 is polystyle SPAR platform hard cabin, and 2 is mooring line, and 3 is mooring pipe, and 4 enclose cylinder out of my cabin for polystyle SPAR platform hard, and 5 is mooring line upper end anchor chain, and 6 are the connection of mooring line middle-end, and 7 is mooring line lower end anchor chain.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is further described.
As depicted in figs. 1 and 2, polystyle SPAR platform hard cabin 1 is outer to be with eight peripheral cylinders 4, and mooring line 2 is divided into four groups, and between the two adjacent groups mooring line 90 ° at interval, in same group between adjacent two mooring lines 5 ° at interval.Every mooring line 2 all is arranged in peripheral cylinder 4 outside faces by mooring pipe 3.The quantity of mooring line 2 and specification can be determined according to calculating.
As shown in Figure 3, the mooring line upper end is connected with peripheral cylinder 4 by mooring pipe 3, and the lower end is connected with the seabed anchor foundation.Mooring line 2 is made up of upper end anchor chain 5, middle-end connection 6, lower end anchor chain 7.The length of upper end anchor chain 5 will guarantee that middle-end connects 6 and can not touch the SPAR main platform body, and the length of lower end anchor chain 7 will guarantee that middle-end connects 6 and can not touch the seabed.
When SPAR platform during marine moving, can cause the change of mooring line 2 shapes, produce a restoring force, reduce the flat-bed displacement.Motion in any direction all has good restriction to the utility model to the SPAR platform.
The utility model is applicable to the polystyle SPAR platform of eight cylinders, can select only mooring line radical and specification by calculating, and reaches the effect that reduces cost.Simultaneously the utility model all has the stormy waves stream of any direction and well resists effect, is specially adapted to the marine site that environmental data lacks.
