Description
Technical field
The present invention relates to method for improving, relate in particular to the method for improving that a kind of submarine cable terminal is landed platform, belong to the offshore oil field of engineering technology.
Background technology
The exploitation of new forms of energy such as offshore oilfield construction and Oversea wind power generation all needs a large amount of extra large cables to be used for connecting center control platform between each production platform or each windmill, is used for the support of energising, communication.The pattern of sea cable mainly comprises: power cable, optical cable, optoelectronic composite cable and Long-distance Control umbilical cables.These extra large cables lay the difference very big with the laying existence of overland cable, and extra large cable laying task is comparatively complicated.
In extra large cable laid processes, need employ specialty shop cable ship and corresponding specialty shop cable equipment, these shop cable equipment comprise: a whole set of system of burying cable machine, diving, underwater robot (ROV), global differential positioning system (DGPS) etc. supports that facility are huge, and cost is higher.Especially under the situation of carrying out deep water shop cable operation and sea situation environmental condition difference, needing large-scale shop cable ship as support, is the industry of excessive risk, high investment.Therefore, extra large cable lays the height of quality, the efficient of worker's method, skill and technique, directly has influence on the cost of engineering.
The sea cable lays and comprises: the seabed of extra large cable is laid and extra large cable terminal is landed platform and laid.
At present, vertically to land the platform operations method as follows for extra large cable terminal:
⑴ adopt hoist engine as the power source of the extra large cable walking of traction, need be installed in advance on the platform; The wire rope pulley of hoist engine is hung above the oral top of cable pillar, platform sea (annotate: be subjected to the influence of the restriction of platform small space, platform production equipment, general suspension height is only about 2 meters) as turning point; Shop cable ship is located near the platform.
⑵ the steel wire penetrating pulley of hoist engine, enter extra large cable pillar, go out pillar bottom horn mouth, turn back to the eye splice shackle that the water surface arrives shop cable ship, steel wire rope again and connect the dilatory head of extra large cable.
⑶ platform hoist engine scrolling haulage cable, shop cable ship discharges extra large cable synchronously, and steel wire rope pulls extra large cable end entry, enters pillar, goes out pillar arrival pillar crown pulley.
So far, extra large cable is taken out and is dragged lifting work and be far from finishing, generally speaking, even the junction box is positioned near the pillar, the length that extra large cable also need be pulled out 12 meters to 15 meters of pillars could satisfy the requirement that terminal is made; In particular cases, the extra large cable that has need be extracted 40 meters just can arrive at the junction box position to 50 meters.
Because extra large cable end arrives pillar top pulley and is obstructed, the hoist engine dynamic failure, traditional method of dragging of taking out is:
⑴ time-out is taken out and is dragged, and temporary fixed extra large cable prevents from gliding;
⑵ untie being connected of steel wire rope and extra large cable end, manually utilizes chain block (jack) to substitute hoist engine and take out piecemeal by rice and drag, and it is intermittent to take out the process of dragging, until pulling out the length of enough advancing junction box's wiring.
Above-mentioned whole operation process not only wastes time and energy, and, when expending engineering shop cable boatman.
Be subjected to the restriction of environmental working condition, marine engineering not only must be provided support to implement by " working ship ", and " working ship " could work and restricted by weather conditions, and the operating time window is very valuable.In extra large cable laying project, especially in the relatively poor marine site of sea situation, shop cable ship mostly is large-scale operation boats and ships, and daily cost is high.Therefore, one save time, work skill and technique in labour-saving can reduce hundreds of thousands even engineering cost up to a million; Sometimes carry previous hour, engineering just might be kept away public attention and be caught up with safety, completion smoothly before a weather window.Based on this kind situation, improve worker's method of the individual work link in the extra large cable laying process, shorten the operating time, increase work efficiency, reduce the operation ship sky, be the target that engineers and technicians lay siege to.And extra large cable terminal is landed the method for improving of platform, namely is one of innovation and creation in this process.
Summary of the invention
Main purpose of the present invention is to overcome the above-mentioned shortcoming that prior art exists, and provide a kind of method for improving that lands the submarine cable terminal of platform, its steel wire rope with hoist engine directly is strapped on the extra large cable, by lockset steel wire rope and extra large cable are connected as a single entity, land in the process of pulling at extra large cable poling, when extra large cable does not arrive at pulley, the cable walking of hoist engine rope traction sea; Treat that extra large cable end arrives pulley, progressively untie the lockset between steel wire rope and the extra large cable, extra large cable is separated with steel wire rope, steel wire rope walks on and passes pulley and arrive at hoist engine, extra large cable is followed steel wire rope, and to go out pillar then be by manually being placed on the deck, whole process is almost works continuously, and extra large cable end is lifted to put in place fast, time saving and energy saving; Reduce the operation ship sky, improved operating efficiency.
The objective of the invention is to be realized by following technical scheme:
A kind of method for improving that lands the submarine cable terminal of platform is characterized in that: adopt following steps:
The first step: start the hoist engine on the cable ship of shop, the steel wire rope of platform hoist engine is dragged on the deck of shop cable ship;
Second step: connect the short rope of an eye splice at the dilatory head of extra large cable;
The 3rd step: one anchor clamps are installed at extra large cable;
The 4th step: the steel wire rope of platform hoist engine is connected with anchor clamps, and, steel wire rope sticked with several bandages be fixed on the extra large cable extremely extra large cable and draw a position;
The 5th step: in extra large cable-end head position, utilize rope cramp that the steel wire rope of hoist engine and short rope are connected as one;
