Abstract

A shallow water platform series with multi-barrel suction type foundation technically features that besides the water feed and drainage system needed by suction-type foundation, an air feed and exhaustion system is arranged on the top of suction-type foundation for realizing self sinking and self floating to omit large lifting and transportation equipment, so greatly reducing the cost of construction on sea.

Description

Shallow water platform series with multi-barrel suction type foundation
The invention belongs to the innovation of the migration of multi-barrel suction type foundation pier, mounting technique.
Present multi-barrel suction type foundation platform is to make the back to hang on barge on the bank with loop wheel machine, is dragged to objective, relends crane ship and hangs entry, and the suction technology of using the step-down of drawing water is finished the bucket base injection bottom platform and installed at last.This migration mounting technique is applicable to the big waters of the depth of water, but more shallow to the depth of water, especially there is following point in Very Shallow Water territory in intertidal zone: 1. large-scale handling equipment often is subjected to depth of water restriction to be difficult to the target approach place; Even 2. large-scale handling equipment can the target approach place, the transportation mounting cost of platform is also higher.
The objective of the invention is to propose a kind of above-mentioned shortcoming that overcomes, make multi-barrel suction type foundation platform series be used in the economically viable technical scheme of shallow water region.
Technical scheme of the present invention: a kind of shallow water platform series with multi-barrel suction type foundation that is used for oil and gas development waterborne, comprise three barrels of single-columns, three barrel of three post, four barrels of single-columns, four barrel of four post and six barrel of six column type platform, by connecing column on the suction type bucket base and the contact member is formed, its common trait be on bucket base, fill except that being equipped with, also be equipped with the drainage system fill, exhaust system.Fill, exhaust system is made up of air pump, valve and the pipeline of water surface remote control.Drown oneself from floating and exhaust with the inflation that these technical condition can the implementation platform bucket base, thereby replace hanging migration, the mount scheme of entry by barging and crane ship.The invention thinking of the technical program is, pressure-bearing and buoyant characteristics according to water body and closed gas, make full use of the inner space of bucket base, by light remote control pump valve piping installation, realize that water, gas in the bucket base space fill row's displacement, move the purpose of drowning oneself and installing from transportation by driving with exhaust to reach the platform inflation.
It is light that the superiority of the technical program is with migration, sinking that it realizes the multi-barrel suction type foundation shallow water platform series required technical equipment to be installed, and it need not large-scale handling equipment, consequently:
(1) making the multi-barrel suction type foundation platform enter marginal oil field shallow water region becomes feasible;
(2) need not carry out platform migration installation waterborne by large-scale handling equipment, can save offshore construction greatly
Expense generally can be economized more than 50%;
Be described further below in conjunction with embodiment and accompanying drawing.Embodiment:
Figure 1 shows that an example of shallow water platform series with multi-barrel suction type foundation, belong to three barrels of single column platforms, by column 1, contact member 2, and bucket base (3) 3 compositions are full steel structure.Roll by steel plate and to be welded.The principal dimensions of bucket base satisfies the inflation self-floating towing in design simultaneously, exhaust is drowned oneself and transferred, and suction is installed and the requirement of carrying stability.
For implementation platform inflation from floating, exhaust is drowned oneself and suction is installed, be provided with at each base bucket top fill, exhaust system and fill, drainage system.As shown in Figure 2.Two systems form by the pump valve pipeline, are terminated at the bucket top down, on be terminated at measure and control device waterborne, the pump valve pipeline of two systems is conventional common commercial product, purchases easily.
The transportation by driving of multi-barrel suction type foundation shallow water platform series, sinking erection procedure were divided into for four steps, with single barrel of signal such as Fig. 3;
1. an inflation is from floating and the platform towage: this moment, the base bucket was in water.Close fill, drainage system, open fill, exhaust system inflates in bucket, a freeboard and a bucket end water cushion reach suitable size on bucket, till being fit to towage and requiring.
2. an exhaust is drowned oneself and bucket end is gone into mud: this moment, the base bucket was positioned at the infield.Rotation is filled, the exhaust system valve, makes it exhaust in the bucket, so the bucket base sinks under action of gravity voluntarily, the bucket end is gone into mud, reaches certain depth, forms the initial sealing condition.
3. the step-down of drawing water, the basic injection of bucket seabed: gas drains in this moment bucket base.Close fill, exhaust system, open fill, drainage system, to the step-down of drawing water of bucket base, form the upper and lower pressure reduction in bucket top, promptly so-called suction, thereby overcome barrel wall resistance with bucket base injection seabed.
4. one continues the step-down of drawing water, and makes barrel base all sink to the seabed, and platform installs.

Claims (2)

1. shallow water platform series with multi-barrel suction type foundation that is used for oil and gas development waterborne, comprise three barrels of single-columns, three barrel of three post, four barrels of single-columns, four barrel of four post and six barrel of six column type platform, by connecing column on the suction type bucket base and the contact member is formed, its common trait be on bucket base, fill except that being equipped with, also be equipped with the drainage system fill, exhaust system.
2. according to the shallow water platform series with multi-barrel suction type foundation of claim 1, it is characterized in that installing on the bucket base fill, exhaust system is the air pump by water surface remote control, valve and pipeline are formed.
