Description
Technical field
The invention belongs to Marine oil and gas resource exploitation equipment, relate to the fibre of a kind of ocean platform deep sea mooring alignment system
Dimension cable.
Background technology
In recent years, in the mooring and positioning system of ocean platform, by traditional catenary mooring System Development to
The side tension cords anchoring system that deep-sea platform uses.
With the development of Mooring Arrangements, anchor hawser material is from typical steel chain, cable wire, to the increasingly extensive Gao Mo of application
Weight northylen (English full name: High modulus polyethylene, be called for short HMPE) fiber transition；This fiber
Also known as ultra-high molecular weight polyethylene (English full name: Ultra High Molecular Weight Polyethylene, letter
Claim UHMWPE).
The manufacture of current ultra-large type volume twisted rope cable machine and application technology are ripe, can manufacture code name (i.e. " approximate diameter
Millimeter ") be 60～160, line density 1800～18000ktex, length 2000～19000m, single quality reach
Twisted rope compiled by the jointless high modulus polyethylene of 60000kg, rope strand or ultra-high molecular weight polyethylene, can be as system with it
The single wire rope core of pool cable.
The wire rope core structure of existing high modulus polyethylene or ultra-high molecular weight polyethylene mooring line has the torsade of single and many
Two kinds of patterns of parallel rope of core (a plurality of 3 bursts of torsades, 8 or 12 strands of volume twisted ropes etc.).
But, the former due to the instability of wire rope core structure, easily produces when mooring line is by tension force in (i.e. the torsade of single)
Raw torsion.
The wire rope core structure of the latter's (i.e. parallel rope of multicore) is extremely loose, and once the protective layer of its outer wrap is impaired,
Then the strength loss of whole mooring line is the summation of each wire rope core strength loss, and this will directly jeopardize ocean platform mooring
Safety；And this kind of mooring line manufacturing, coiling when the deviation of each parallel cable core length that causes be relatively big, thus make
The intensity becoming mooring line declines more than 10.
Additionally, prior art is in the manufacture process of mooring line, whole piece rope, cable is used to carry out wire rope core and mooring line
The compound technique of polyurethane, this not only manufacturing cost high, and reduce the effect of drawing and setting.
Content of the invention
The technical problem to be solved is to provide a kind of high modulus polyethylene or ultra-high molecular weight polyethylene list
Strand mooring line compiled by core, and it uses single high modulus polyethylene or ultra-high molecular weight polyethylene to compile twisted rope as mooring line
Wire rope core, wire rope core uses volume to tangle structure, and its Stability Analysis of Structures will not produce torsion at mooring line when by tension force, can be relatively
The cost that manufacture mooring line being greatly reduced, and making fixed effect be able to good holding, its ultimate strength is high,
Can make overlength mooring line, single quality is maximum up to 60 tons.
The technical scheme is that a kind of high modulus polyethylene of offer or ultra-high molecular weight polyethylene single compile strand system
Pool cable, uses high modulus polyethylene or ultra-high molecular weight polyethylene to compile twisted rope and is combined/braiding with PE yarn, torsade；
It is characterized in that: carry out compiling strand with jointless ultra-high molecular weight polyethylene or high modulus polyethylene rope strand, constitute system
The single wire rope core of pool cable；It is wrapped in outside wire rope core with PE yarn braiding or polyester belt, constitute described single and compile strand mooring
The setting layer of cable；With polyester twist thread, torsade is woven in outside setting layer, constitute described single compile strand mooring line sheath
Layer.
Concrete, its described single compiles the compound of strand mooring line, uses aqueous polyurethane to high modulus polyethylene or super
High molecular weight polyethylene ropes stock and polyester are twisted thread, torsade is combined, natural drying.
Its described single is compiled strand mooring line and is used single wire rope core being designed ultimate strength more than 5 by more than mooring line
Tension force stretching under carry out the parcel of setting layer, eliminate the structural stretch of mooring line.
Further, described single is compiled strand mooring line and is used single high modulus polyethylene or ultra-high molecular weight polyethylene
Compile the wire rope core as mooring line for the twisted rope.
The wire rope core that its described single compiles strand mooring line uses volume to tangle structure.
Its described single volume strand mooring line, when compiling twisted rope stranding, carries out the compound of polyurethane；Polyester twist thread,
Torsade carry out polyurethane compound after, then weave the sheath of mooring line.
Further, the minimum ultimate strength that described single compiles strand mooring line is 2500kN～20000kN.
The joint length that its described single compiles strand mooring line is 19000m to the maximum, and single single compiles strand mooring line
Big quality is 60 tons.
Compared with the prior art, the invention have the advantage that
1. use single high modulus polyethylene or ultra-high molecular weight polyethylene to compile the wire rope core as mooring line for the twisted rope, its knot
Structure is stable, will not produce torsion at mooring line when by tension force；Once protective layer is impaired, owing to compiling the structure of twisted rope
More tight and each rope strand has centripetal cohesive force, makes the strength loss of mooring line be only and compiles rope on twisted rope cross section
The maximum of stock strength loss, this will improve the security of ocean platform mooring；
2. wire rope core uses volume to tangle structure, this makes mooring line manufacturing, coiling when the deviation of each rope strand length that causes be
Minimum, thus do not result in the decline of intensity；
3. use wire rope core to carry out wrapping of setting layer under by more than the tension force stretching of mooring line ultimate strength more than 5
Wrapping up in, eliminating the structural stretch of mooring line under the effect of PE yarn centripetal force, its technique simply can obtain good
Fixed effect；
4. carry out when twisted rope stranding compiled by high modulus polyethylene or ultra-high molecular weight polyethylene the compound of polyurethane and
Polyester is twisted thread, torsade carry out polyurethane compound after weave the sheath of mooring line again, so not only eliminate check and regulate operation,
Decrease the loss of polyurethane, the cost reducing manufacture greatly, and it is good to make fixed effect be able to
Keep；
5. using the mooring line of the technical program, its minimum ultimate strength is 2500kN～20000kN, and length is maximum
Up to 19000m, meet the requirement of ocean platform deep sea mooring positioning, can be used for ocean platform, drill ship, float
Formula produces the mooring line of the deep sea mooring such as oil storage wheel positioning, be also applicable to ocean platform dispatch from the factory towage when important dress
Standby overlength, the towing cable of superelevation strength.
