Abstract
The invention relates to a bottom hull type mobile platform and a launching technology of the bottom hull type mobile platform. The bottom hull type mobile platform comprises a deep tank, a shallow tank, lifting devices, spud legs and a bottom hull; the lower portion of the deep tank of the platform enters a concentric-square-shaped space of the bottom hull, so that the bottom of the bottom hull is aligned with a base plate of the platform; and the platform can be built on a slipway, launching through an air bag can be achieved, and the investment cost is reduced. According to the bottom hull type mobile platform and the launching technology, the immersion depth of the platform can be reduced, the requirement for a tug is low, and convenience is brought to application of the mobile platform to oil fields in shallow sea.
Description
Technical field
The present invention relates to a kind of mobile platform and Launching processing thereof, particularly about a kind of settling type mobile platform and Launching processing thereof.
Background technology
In recent years, along with oil demand is increasing, oil consumption increase year after year, China has entered the later development stage in the extensive oil field of exploitation, explored, can for exploitation self-contained high-quality reserves oil field very few, therefore the exploitation of marginal oil field becomes more and more important. Be applicable to the conventional settling type mobile platform of offshore marginal oilfield, its structure is to be mainly provided with mat in the bottom of platform, but mat bottom is not concordant with platform floor, thereby build the side and Launching processing to platform are had relatively high expectations, need in dock, build, bring thus high build the side investment.
Present patent application has proposed settling type mobile platform and Launching processing thereof just under this background.
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 settling type mobile platform and Launching processing thereof, by the deep tank bottom of platform is entered in the three-back-shaped space of mat, realize flushing of mat bottom and platform floor, platform can be built at building berth, and can use air bag to carry out lower water, reduce cost of investment. The present invention can reduce platform draft, to tugboat require lowly, provide convenience for mobile platform is applied to shallow-water oilfield.
The object of the invention is to be realized by following technical scheme:
Settling type mobile platform, include deep tank, shallow cabin, lowering or hoisting gear, spud leg, mat, it is characterized in that the moldeed depth of described deep tank is greater than the moldeed depth in described shallow cabin, described deep tank is positioned at the middle part of platform, the cabin of described platform except described deep tank is described shallow cabin, described shallow freight space is in described platform bow stern, described shallow cabin is provided with several described spud legs, described spud leg is provided with several described lowering or hoisting gears, the bottom of described spud leg is connected with described mat, described mat adopts three-back-shaped planar structure, described mat is positioned at described deep tank projected position outside, the moldeed depth of described deep tank is the moldeed depth in described shallow cabin and the moldeed depth sum of described mat, the type that the type length of described mat is less than described platform is long.
The Launching processing of settling type mobile platform, comprises the following steps:
(1) settling type mobile platform is built on building berth, and after having built, the bottom of the deep tank of platform is concordant with the bottom of mat;
(2) put into air bag inflation in platform lower support structure;
(3) after air bag installation, by tractive, platform is rolled on air bag, thus water under implementation platform.
Beneficial effect of the present invention: the present invention is owing to adopting technique scheme, by the deep tank bottom of platform is entered in the three-back-shaped space of mat, realize flushing of mat bottom and platform floor, platform can be built at building berth, and can use air bag to carry out lower water, reduce cost of investment. The present invention can reduce platform draft, to tugboat require lowly, provide convenience for mobile platform is applied to shallow-water oilfield.
Below in conjunction with drawings and Examples, the present invention will be further described.

Detailed description of the invention
Below in conjunction with accompanying drawing and example, the present invention is described in detail.
As shown in Figure 1-2, the present invention includes deep tank 3, shallow cabin 4, lowering or hoisting gear 5, spud leg 2, mat 1, deep tank 3 moldeed depth are greater than shallow cabin 4 moldeed depth, deep tank 3 is positioned at platform middle part, platform cabin except deep tank 3 is shallow cabin 4, shallow cabin 4 is positioned at platform bow stern, shallow cabin 4 is provided with 4 spud legs 2, on spud leg 2, be provided with 4 lowering or hoisting gears 5, the bottom of spud leg 2 is connected with mat 1, mat 1 adopts three-back-shaped planar structure, mat 1 is positioned at deep tank 3 projected position outsides, bottom, the moldeed depth of deep tank 3 is the moldeed depth in shallow cabin 4 and the moldeed depth sum of mat 1, the type that the type length of mat 1 is less than platform is long.
The Launching processing of settling type mobile platform, comprises the following steps:
(1) settling type mobile platform is built on building berth 7, after having built, deep tank 3 bottoms of platform are concordant with mat 1 bottom;
(2) platform lower support structure is cleared up, after cleaning, put into air bag 8 inflation;
(3) after air bag 8 installations, remove the constraint to platform, by tractive, platform is rolled on air bag 8, thus water under implementation platform.
The above, it is only preferred embodiment of the present invention, not the present invention is done to any pro forma restriction, any simple modification, equivalent variations and modification that every foundation technical spirit of the present invention is done above embodiment, all still belong in the scope of technical solution of the present invention.
