Abstract
The utility model discloses a kind of submarine pipeline pipe crimping laying apparatus.The utility model includes the steel floating drum for providing buoyancy, winds the drum apparatus of pipe crimping and the device that tows the head for drawing, and steel floating drum is symmetrically fixed on main platform frame, and drum apparatus is mounted on main platform, and the device that tows the head is mounted on main platform front end.The utility model is using pipeline towed equipment instead of expensive pipe laying barge, and with mobility strong, the big common tugboat of selectivity disposably, rapidly completes the installation of pipeline in the method for self installation.
Description
Technical field
The utility model is related to seas to convey oil plant technical field, and more specifically, it relates to a kind of submarine pipeline pipe crimpings
Laying apparatus.
Background technology
Common pipe installation mode divides pipelaying vessel metbod and dilatory method.Pipe laying barge has S types, J-type and pipe crimping type again, wherein rolling up
Pipe pipe laying barge is suitable for deep water, flexible pipe submerged pipeline is laid with.Pipe laying barge is costly, it is limited to be applicable in waters, can not meet simultaneously
Requirement that pipeline seashore logs in and ultra-deep-water.
Dilatory method generally has bottom to drag, middle part is dilatory, it is floating drag, dragged the bottom of from, these types of mode by sea situation, pipelaying rate and
Expense etc. has the influence of larger unfavorable factor, as follows：
Bottom is dragged, and advantage is：Being gushed ring by wave is influenced small, and track in place is easy to control, small to pipeline fatigue damage, disadvantage
It is：Higher to the horsepower requirements of tugboat, pipeline coatings are possible to damage.
Middle part is dilatory, and advantage is：Need the horsepower of tugboat smaller, it is smaller to the damage of pipeline, to landform no requirement (NR)；Disadvantage
It is：Track in place is not easily controlled, and the fatigue damage of pipeline is slightly larger.
Floating to drag, advantage is：Need the horsepower of tugboat smaller, pipeline trajectory is intuitive, the disadvantage is that：By water surface wave and ocean current
It is affected, the fatigue damage of pipeline is larger, and track in place is not easily controlled, and needs a certain number of monitoring ships.
It is dragged the bottom of from, advantage is：Need the horsepower of tugboat smaller, it is smaller to the damage of pipeline, the disadvantage is that：Have centainly to landform
Requirement, need control floating drum and ballast weight.
Utility model content
The purpose of this utility model is to provide a kind of simple pipelayer attachment of alternative expensive pipe laying barge.The device not only can be with
Used in ultra-deep water area, while shallow water pipe laying is can be used for, submarine pipeline terminal (PLEM) can also be pre-installed and ditching plow is complete
At pipeline system self installation, to realize most economical reliable pipe laying mode.
The utility model submarine pipeline pipe crimping laying apparatus, including the roller dress of the steel floating drum of buoyancy, winding pipe crimping is provided
It sets and for the dilatory device that tows the head, steel floating drum is symmetrically fixed on main platform frame, drum apparatus is flat mounted on main body
On platform, the device that tows the head is mounted on main platform front end.
The drum apparatus includes cylinder, pedestal, idler wheel, reel releasing mechanism；Pipeline is rolled up on roller shaft, by power-actuated
Transmission device control volume is put.
Steel floating drum is equipped with air injection and exhaust system, the injection of water and exhaust system.
The utility model advantageous effect specific as follows：
The utility model is using pipeline towed equipment instead of expensive pipe laying barge, and with mobility strong, selectively big is general
Logical tugboat disposably, rapidly completes the installation of pipeline in the method for self installation.Simultaneously can increase with pipe end terminal (PLEM),
The disposable system self installation for completing pipeline such as furrow making dveice after corresponding.With traditional pipe laying barge or dragging construction method phase
Than, have short time limit, expense is low, the advantages such as efficient, and the technology once at sea petroleum industry maturation popularization will have it is huge
Big economic benefit.
The utility model combines deep water pipe-laying technique and simply dilatory pipe-laying technique, and pipeline is discharged by reel to be laid,
The pipe-laying device also has the part transportation function of ship using natural buoyancy, can deliver remote apply of pipeline progress and drag, be not necessarily to
The lower water of lifting.Its own drinking water is small, can be as possible close to bank.
Description of the drawings
Fig. 1 is the utility model structure top view；
Fig. 2 is the utility model structural front view.
Specific implementation mode
Utility model device is described further below in conjunction with the accompanying drawings.
As shown in Figure 1, 2, submarine pipeline pipe crimping laying apparatus includes the steel floating drum 1 for providing buoyancy, winds the roller of pipe crimping
Device 2 and for the dilatory device 3 that tows the head, steel floating drum is symmetrically fixed on 4 frame of main platform, and drum apparatus is mounted on
On main platform, the device that tows the head is mounted on main platform front end.Major part is as follows：
(1) pipeline：The pipeline of quasi- laying is welded in advance, carries out corresponding anti-corrosion, is then involved in prefabricated pipeline
Roller；
(2) drum apparatus：By cylinder (according to pipeline diameter, wall thickness and laying length choose reel diameter and length),
Pedestal, idler wheel, volume, laying mechanism composition.
(3) head is drawn：Front end setting draws head connection tugboat and carries out line layout.
The present apparatus can select it is floating drag mode transport it is can berthing to tugboat, apart from land nearest offshore location, lead to
Crossing traction rope makes line end on roller be connected with land anchor point, then by giving floating drum internal water flooding, control device whole
Body stability；The tugboat attachment device other end simultaneously draws the device and carries out pipe installation.
Embodiment described above is only that this creation utility model type device preferred embodiment is described, not pair
The conception and scope of this creation utility model type device is defined, and is not departing from this creation utility model type device design philosophy
Under the premise of, ordinary engineering and technical personnel makes the technical solution of this creation utility model type device in this field various changes
Shape and improvement should all belong to the protection domain of this creation utility model type device.
