Description
Technical field
The present invention relates to a kind of paving system, particularly relate to a kind of deep water quick paving system of J type, be applied to deep water and the laying of ultra-deep-water submarine pipeline and standpipe.
Background technology
In the past few decades, deep water laying-out tube process technology is to make us the development of unthinkable speed, it now is possible to the deep development petroleum resources of more than 10000 feet, but this is not also the limit.World ocean oil is constantly to deep-water developments, and the technology that deep underwater pipes is laid requires also more and more higher.The high speed development of world ocean petroleum industry has promoted the fast development of deep water pipe-laying technique, has also driven the fast development that lifting pipe laying vessel is equipped.At present in deepwater projects, the laying method of pipeline mainly has three kinds: S type to lay, reel is laid and J type is laid.It is a kind of novel lay method that J type is laid, and by laying tower when standpipe is transferred, leaves pipe laying barge with near normal state, transfers to seabed, and after end arrives subsea wellheads, standpipe configuration presents J type.J type is laid and is ensured that pipeline is in process of deployment, more press close to " nature " state, stress state maintains better, the laying tension force needed is less, therefore bottom tension is also relatively small, decreases the free span of pipeline, and the close together of touchdown point and pipe laying barge, it is easy to dynamic positioning, less by external influence.At present, particularly in (depth of water is more than 1500m) in ultra-deep-water project in deep water engineering project, J type laying-out tube process, according to the advantage of self, is widely used in practical engineering project.
Although the security performance that improve standpipe decentralization process laid by J type, but exists and lay inefficient problem.Owing to standpipe needs laying work such as completing welding-Non-Destructive Testing-coating-transfer on tower in J type process of deployment, and these flow processs cannot be synchronously performed, and by restrictions such as number of devices, speed laid by typical case's J type is 1-1.5 km/sky, causes that standpipe mounting cost is higher.
In sum, research by the reference to external advanced J type laying technology and the key technology to comparatively ripe J type laying project, consider some difficult problems in current pipe laying process, a kind of deep water quick paving system of J type of design herein, both there is higher laying ability, the installation of some key equipments can be completed again, improve the feasibility that J type is laid.

Compared with prior art, the invention has the beneficial effects as follows: (1) improves pipe laying speed.Before pipeline welding, centering and preheating about need 2 minutes, and the pipeline welding time about needs 12 minutes, and Non-Destructive Testing about needs 5 minutes, and application about needs 3 minutes, and elevator lowering velocity is about 12.2m/min.Therefore three designed node pipe laying system theories laying speed are:
24 × 60 ÷ { (2+12+5+3)+(12.2 × 4 ÷ 12.2) } × 12.2 × 4=2702.8m/d
Compare typical case's J type and lay speed 1.5km/d improved efficiency 80.2%.
(2) paving mode of 1 × 4 node (having 1 section of 4 node pipe to be on laying tower to carry out laying operation, every section of 4 long 48.8m of node pipeline) can be completed.Use elevator to substitute stretcher with winch, mainly have 3 advantages (1) to improve pipeline lowering velocity, accelerate to lay efficiency.Stretcher operation principle is that pipeline external surface is applied suitable pressure, utilizes frictional force balancing gravity, and lowering velocity can not be too fast.Elevator is utilize to weld pipe neck in advance outside pipeline section tip section with winch operation principle more, gripper jaw of shaping in elevator is tightly mutually embedding with pipe neck under the help of hydraulic press, pipeline section evagination pipe neck cross section balance pipeline section gravity, lowering velocity faster than stretcher (2) uses stretcher, during upper pipe, end of line height necessarily be greater than stretcher tip height, in order to improve efficiency, lay tower and be necessarily designed to 2 × 4 joint forms, so being left out all the other device height, laying Deethanizer design height and being at least 96m (12 × 2 × 4=96).But use elevator, does not limit end of line height, it may be achieved pipe mode on 1 × 4 node, designed laying tower height degree is 52m, height reduction more than 45%, alleviates laying tower weight amount simultaneously.(3) pipeline section cross section must be applied pressure by stretcher, it is possible to producing circumferential deformation, pipeline section outer surface is not then applied any pressure by elevator and winch, improves operational security.
(3) design of tube feeding device, decreases the operation that in pipe process, some are unnecessary, and the transmission making pipeline section is simple.Cursor coordinates with loading arm, it is ensured that pipeline precisely enters and transfers path.Relatively big owing to loading 4 node pipeline section quality, it is rotatably connected in rotary course stress for reducing, it is ensured that safety work, changes loading arm and cursor combining form, become loading arm and provide only vertical plane motion, cursor provides only horizontal plane motion.
(4) compared to U.S.'s Pub.No:US2008/0118311A1 patent, installing, operating process there are 2 advantages: in (a) United States Patent (USP), pipeline first passes through loading arm and rises to laying tower middle level, clamp pipeline with rear line elevator and winched to laying tower top layer, and pipeline is directly promoted to installation tower top layer by loading arm in the present invention, eliminate this loaded down with trivial details step of pipeline elevator, the transmission making pipeline section is simple, minimizing equipment uses, alleviate weight, improve work efficiency.B in () United States Patent (USP), pipeline rises to installation tower upper strata, pipeline fixed by three fixed clamps on upper strata subsequently, then three the movable clamps installing tower lower floor move to installation tower upper strata by slide rail, movable clamp is clamped pipeline fixed clamp subsequently and is unclamped pipeline, and last movable pipeline moves to installation tower lower floor thus completing the conveying of pipeline.
(5) increase the prefabricated work of terrestrial pipeline, reduce offshore pipeline welding job, improve and lay efficiency, save expense.Welder and the cannot-harm-detection device are arranged in same working position, if welding detection is off quality, can process in time, reduce unnecessary operation, it is to avoid efficiency is laid in impact.Pipeline welding, detection and coating procedure, position is not moved, it is ensured that installation quality meets index.
(6) can realize laying tower angle to regulate smoothly between 70 ° to 110 °, it is possible to meet the laying requirement of different water depth and caliber, reduce the stress on pipeline section top, it is ensured that being smoothed out of pipelaying work.Suspension platform is increased, it is achieved the installation of the key equipments such as PLET, PLEM, it is ensured that while laying operational security, also improve laying efficiency laying tower bottom.By regulate lay tower angle, stretcher applies power and coordinates the lower pipe speed controlling pipeline and form under water with ship power, keep pipeline stability, reduce bending stress and deform to prevent unstability or to destroy.
