Description

A kind of quick paving system of deep water J-type

Technical field

This utility model relates to a kind of paving system, particularly relates to a kind of quick paving system of deep water J-type, is applied to deep water and surpasses Deep-water subsea pipeline and the laying of 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 more than 10000 feet Deep development petroleum resources, but this is not the most the limit.Deep underwater pipes constantly to deep-water developments, is laid by world ocean oil Technology requires more and more higher.The high speed development of world ocean petroleum industry has promoted the fast development of deep water pipe-laying technique, also carries Move the fast development of lifting pipe laying vessel equipment.At present in deepwater projects, the laying method of pipeline mainly has three kinds: S type paving If, reel lay and J-type lay.It is a kind of novel lay method that J-type is laid, and by laying tower when standpipe is transferred, hangs down with approximation Straight state leaves pipe laying barge, transfers to seabed, and after end arrives subsea wellheads, standpipe configuration presents J-type.J-type is laid Ensureing that pipeline, in process of deployment, more presses close to " naturally " state, stress state maintains preferably, and the laying tension force of needs is less, Therefore bottom tension is the most relatively small, decreases the free span of pipeline, and touchdown point and pipe laying barge is close together, it is simple to Dynamic positioning, less by external influence.At present, in deep water engineering project, especially in ultra-deep-water project, (depth of water exceedes 1500m), J-type laying-out tube process, according to the advantage of self, is widely used in practical engineering project.

Although J-type lays the security performance that improve standpipe decentralization process, but exists and lay inefficient problem.Due to standpipe J-type process of deployment needs laying work such as completing welding-Non-Destructive Testing-coating-transfer on tower, and these flow processs cannot be together Step is carried out, and is restricted by number of devices etc., and it is 1-1.5 km/sky that typical case's J-type lays speed, causes standpipe mounting cost relatively High.

In sum, by the reference to external advanced J-type laying technology and the key to more ripe J-type laying project The research of technology, considers some difficult problems during current pipe laying, designs a kind of quick paving system of deep water J-type herein, Both there is higher laying ability, the installation of some key equipments can have been completed again, improved the feasibility that J-type is laid.

(2) 1 × 4 node can be completed (have 1 section of 4 node pipe to be on laying tower to carry out laying operation, every section of 4 node pipelines Long 48.8m) paving mode.Use elevator to substitute stretcher with winch, mainly have 3 advantages (1) to improve pipeline and transfer Speed, accelerates to lay efficiency.Stretcher operation principle is that pipeline external surface is applied suitable pressure, utilizes frictional force balance weight Power, lowering velocity can not be too fast.Elevator is to utilize to weld pipe in advance outside pipeline section tip section with winch operation principle more Neck, gripper jaw of shaping in elevator is mutually the most embedding with pipe neck with the help of hydraulic press, pipeline section evagination pipe neck cross section balance pipeline section weight Power, lowering velocity faster than stretcher (2) uses stretcher, and during upper pipe, end of line height necessarily be greater than stretcher tip height, In order to improve efficiency, laying tower and be necessarily designed to 2 × 4 joint forms, so not considering remaining device height, laying Deethanizer design high Degree at least 96m (12 × 2 × 4=96).But use elevator, does not limit end of line height, can realize on 1 × 4 node Pipe mode, designed laying tower height degree is 52m, height reduction more than 45%, alleviates laying tower weight amount simultaneously.(3) stretcher Pipeline section cross section must be applied pressure, it is possible to can produce circumferential deformation, pipeline section outer surface is not applied by elevator and winch Any pressure, improves operational security.

(3) design of tube feeding device, decreases some unnecessary operations during pipe, 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, for reducing It is rotatably connected on stress in rotary course, it is ensured that safety work, changes loading arm and cursor combining form, become loading arm Providing only vertical plane motion, cursor provides only horizontal plane motion.

(4) compared to U.S.'s Pub.No:US 2008/0118311A1 patent, there are 2 advantages in operating process installing: A in () 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 paving If tower top layer, and in this utility model, pipeline is directly promoted to install tower top layer by loading arm, this is loaded down with trivial details to eliminate pipeline elevator Step, the transmission making pipeline section is simple, reduces equipment and uses, alleviate weight, improves work efficiency.(b) United States Patent (USP) Middle pipeline rises to installation tower upper strata, and pipeline fixed by three fixed clamps on upper strata subsequently, then install tower lower floor three Movable clamp moves to install tower upper strata by slide rail, and movable clamp is clamped the most fixed clamp of pipeline and unclamped pipeline, Rear movable pipeline moves to install tower lower floor thus completes the conveying of pipeline.

(5) increase the prefabricated work of terrestrial pipeline, reduce offshore pipeline welding job, improve and lay efficiency, save expense.Welding Device and the cannot-harm-detection device are arranged in same working position, if welding detection is off quality, can process in time, and it is unnecessary to reduce 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 finger Mark.

(6) can realize laying tower angle to regulate smoothly between 70 ° to 110 °, the laying of different water depth and caliber can be met Requirement, reduces the stress on pipeline section top, it is ensured that being smoothed out of pipelaying work.Suspension platform is increased laying tower bottom, it is achieved The installation of the key equipments such as PLET, PLEM, it is ensured that also improve laying efficiency while laying operational security.By regulation Lay tower angle, stretcher applies power and coordinates down tube speed and the form under water of control pipeline, holding pipeline stabilization with ship power Property, reduce bending stress and deformation to prevent unstability or to destroy.
