Description
Technical field
Built and lifting side the present invention relates to ship domain, more particularly to a kind of FPSO multipoint moorings cable stopper dependency structure
Method.
Background technology
Floating type production, storage and offloading device (Floating Production Storage and Offloading, below
Referred to as " FPSO ") be used as " offshore oil factory ", can by the mixed liquors such as the oil gas water from sub-sea drilled wells by working process into
Qualified crude oil or natural gas storing are conveyed to the oil of shuttle when reserves reach to a certain degree in oil cargo tank by outer defeated system
Wheel, it is convenient to provides power for marine oil tanker, with capacity of anti-storm it is strong, adapt to depth of water scope deeply, storage/emptying ability greatly
Advantage, is widely used in the deep-sea away from seashore and the exploitation of marginal oil field.
FPSO mainly includes undersea system, hull system, anchoring system, oil vapor treatment system and oil transportation and outer defeated system
Deng.Wherein, FPSO can be fixed on by predetermined maritime area by anchoring system, it can be ensured that follow-up work is normally carried out, it is seen then that mooring
Whether reliable system installation construction is serves vital effect in FPSO.Existing Mooring Arrangements are broadly divided into single-point system
Two kinds of pool and multipoint mooring, and multipoint mooring is because it is simple, economical, enable hull to install more oil transportation standpipe and umbilical cord system
The advantages such as system are widely used.
Multi-buoy mooring system is that mooring system has multiple contact points with hull, and wherein mooring system is filled including multigroup mooring
Put, the mooring gear includes being fixed on playing chain apparatus, being fixed on the cable stopper of hull sides, with cable stopper consolidate for hull upper end
Surely the guide chain pipe and mooring cable connected, the mooring cable is after chain apparatus is drawn from described, around being located on the cable stopper and lead to
Cross the guide chain piping pool seabed.The cable stopper system generally includes the connection member of cable stopper, is fixed in connection member
Lead cable axle and anchor chain guide wheel.If the cable stopper system when installing first by the connection member of cable stopper and upper support member and
Lower support member is fixedly connected, then guide chain pipe is fixed on after cable stopper seat, and integral hoisting is welded on ship hull plate, then
When fixed because cable stopper is installed, not only need to consider that whole cable stopper is fitted in the position of ship hull plate and with ship hull plate
Degree, it is also contemplated that position and angle between the angle of the Kong Yuqi chain apparatus that snubs the chain of cable stopper, guide chain Guan Yuqi chain apparatus
The problems such as, the difficulty of integral hoisting welding will be increased, increase the requirement to instrument and equipment；And during integral solder, position and angle
The regulation difficulty of degree is big, also considerably increases workload, expends substantial amounts of manpower and materials.
The content of the invention
