Abstract
The present invention relates to an octagon FDPSO rapid construction method comprising steps of: (1) building a lower buoyancy aid and an internal function cabin of the octagon FDPSO on a berth or on a plane ground; (2) at the same time, dividing an upper buoyancy aid of the FDPSO into a plurality of functional blocks and conducting individual construction of the plurality of functional blocks on land in the peripheral of a dock; (3) launching the lower buoyancy aid after the construction thereof and dragging the whole body of the buoyancy aid within the dock, closing a dock gate, withdrawing water from the dock so as to anchor the lower buoyancy aid within the dock; (4) lifting the plurality of functional areas the construction of which has been completed to the upper part of the lower buoyancy aid through a suspension apparatus for modular assembly and folding; (5) installing and debugging relevant work equipments of each functional area; (6) opening the dock gate and filling in water so as to make the octagon FDPSO float in the ocean under seawater buoyancy effect. The synchronous construction of the upper and lower parts of the octagon FDPSO of the present invention shortens the time for building required on berth, dock or plane ground, thus achieving the purpose of rapid construction.
Description
Technical field
The present invention relates to a kind of fast construction method of octagon FDPSO, belong to field of ocean engineering.
Background technology
In order to meet economy and the practicality requirement of ocean marginal oil field, be developed and a kind ofly integrate drilling well, oil recovery, production, oil storage and outer defeated octagon FDPSO (floating drilling, production, storage and offloading unit, floating type well drilling, production storage handler) Multifunctional marine design library part editor and reuse.As Figure 1 and Figure 4, the bottom buoyancy aid 1 of octagon FDPSO, in order to meet the requirement of stability, is designed to size and from larger eight prism structures of weight average, the inside of eight prisms is provided with multiple functional cabin 11 by dividing plate by this device.Meanwhile, in order to meet the demand such as drilling and storage of oil, the deck of the top buoyancy aid 2 of the octagon FDPSO be wholely set with bottom buoyancy aid 1 being divided into the mac function of multiple intensive layout, each mac function being configured with corresponding working equipment 22.
Because this octagon FDPSO volume is comparatively large, therefore the construction of this device can only adopt at present and build in dock after floating launching, build on building berth after dynamic launching or build rear dragging move to half and dive and refute the three kinds of mode of construction that launch a ship on level land.But all there is certain defect in these three kinds of mode of construction, when adopt build in dock time, due to octagon FDPSO cross section and height dimension is excessive, functional module arrange intensive, therefore make the production cycle in dock extend; When employing is built on building berth, because the principal dimensions of octagon FDPSO and body are from great, the bearing capacity of conventional launching platform and size can not meet its lower water demand, therefore need to carry out large-scale redevelopment to building berth, but which not only adds shipbuilding cost, but also there is certain potential safety hazard, make production cycle become longer; When employing is built on level land, although dock and building berth resource can not be taken, but because octagon FDPSO principal dimensions and body are from great, level land is built and is required higher to harbour foundation bearing, corresponding barge etc. of half-and-half diving is built resource allocation request and also can correspondingly be improved, and then adds the cost of shipbuilding.
Summary of the invention
For the problems referred to above, the object of this invention is to provide and a kind ofly can reduce dock, building berth resource occupation time and significantly reduce the fast construction method of the octagon FDPSO of laid down cost pacifically.
For achieving the above object, the present invention takes following technical scheme: a kind of fast construction method of octagon FDPSO, and it comprises following content:
1) on building berth or level land, carry out the bottom buoyancy aid of octagon FDPSO and the construction in its inside function cabin;
2) carry out step 1) while, the top buoyancy aid of octagon FDPSO is divided into multiple mac function to build respectively by the surrounding lands of dock;
3) after the bottom buoyancy aid of octagon FDPSO has been built, by its lower water and entirety drags in dock, close dock gate and also dock is drawn water, make the bottom buoyancy aid pedestal of octagon FDPSO in dock;
4) by constructed multiple mac function by hanging apparatus respectively handling carry out modularization assembling to the top of the bottom buoyancy aid of octagon FDPSO and close up, make it form the top buoyancy aid of a complete octagon FDPSO;
5) in the installation and adjustment work of the enterprising line correlation working equipment of each mac function;
6) open dock gate and make water-filling in dock, octagon FDPSO entirety under buoyant of sea water effect floats on marine, and then the lower water conservancy project completing octagon FDPSO is done.
Build size and weight demands that the described building berth of the bottom buoyancy aid of described octagon FDPSO or level land need meet the bottom buoyancy aid of described octagon FDPSO.
The described hanging apparatus used needs size and the weight demands of content with funtion block.
Described hanging apparatus adopts large-sized gantry to hang or marine crane barge hanging apparatus.
The present invention is owing to taking above technical scheme, it has the following advantages: 1, the present invention builds owing to octagon FDPSO to be divided into upper and lower two parts simultaneously, therefore shorten and take the time that resource built pacifically by building berth, dock, increasing not significantly under laid down cost prerequisite, reaching fast construction object.2, the present invention builds due to top buoyancy aid is divided into multiple mac function, and by hanging apparatus, each mac function is carried out modularization assembling at buoyancy aid top, bottom and closed up, operation side has been carried out plane expansion by actv., thus shortens production cycle, reduces laid down cost.
