Description
Technical field
The present invention relates to a kind of quick method of construction of octagonal FDPSO, belong to field of ocean engineering.
Background technology
In order to meet the economy of ocean marginal oil field and practicality requirement, be developed a kind of collection drilling well,
Oil recovery, production, oil storage and outer defeated octagonal FDPSO (the floating drilling, production, storage being integrated
And offloading unit, floating type well drilling, production storage handler) Multifunctional marine design library part editor and reuse.As Figure 1 and Figure 4, should
Device is designed as size and eight larger ribs of conducting oneself with dignity in order to meet the requirement of stability, by the lower float 1 of octagonal FDPSO
Rod structure, the inside of eight prisms are provided with multiple functional cabins 11 by partition plate.Meanwhile in order to meet the drilling of oil and storage
Etc. demand, the deck of the Upper float 2 for the octagonal FDPSO being wholely set with lower float 1 is divided into multiple intensive arrangements
Mac function, be configured with corresponding working equipment 22 in each mac function.
Since octagonal FDPSO volumes are larger, the construction of the device can only use in dock after construction at present
Floating launching, dynamic launching or build rear dragging on level land and move to partly latent and refute the three kinds of sides of construction that launch a ship after being built on building berth
Formula.But these three mode of construction are there are certain defect, when using being built in dock, due to cutting for octagonal FDPSO
Face and height dimension is excessive, function module arrangement is intensive, hence in so that the construction period in dock extends；When using in building berth
During upper construction, since the principal dimensions and body of octagonal FDPSO is from great, the bearing capacity and size of conventional launching platform cannot expire
Its lower water demand of foot, therefore large-scale redevelopment need to be carried out to building berth, but which not only adds shipbuilding cost, but also exist
Some potential safety problems so that construction period becomes longer；When using being built on level land, although dock and ship will not be taken
Taiwan investment source, but since octagonal FDPSO principal dimensions and body are from great, phase more demanding to harbour foundation bearing is built on level land
Reply partly latent barge etc. is built resource allocation request and also can accordingly be improved, and then adds the cost of shipbuilding.
The content of the invention
In view of the above-mentioned problems, the object of the present invention is to provide one kind can reduce dock, building berth pacifically resource occupation when
Between and be greatly lowered the quick method of construction of the octagonal FDPSO of construction cost.
To achieve the above object, the present invention takes following technical scheme：A kind of quick method of construction of octagonal FDPSO,
It includes herein below：
1) lower float of octagonal FDPSO and the construction in its inside function cabin are carried out on building berth or level land；
2) while step 1) is carried out, by the Upper float of octagonal FDPSO point on the surrounding lands of dock
Built respectively for multiple mac functions；
3) after the completion of the lower float of octagonal FDPSO is built, drag its lower water and integrally into dock, close depressed place
Door simultaneously draws water dock, makes the lower float pedestal of octagonal FDPSO in dock；
4) constructed multiple mac functions are distinguished into handling to the lower float of octagonal FDPSO by hanging apparatus
Top carries out modularization assembling and closes up, and it is formed the Upper float of a complete octagonal FDPSO；
5) installation and the debugging efforts of work related devices are carried out in each mac function；
6) opening dock gate makes water-filling in dock, octagonal FDPSO integrally floated under buoyant of sea water effect it is marine, and then
The lower water conservancy project for completing octagonal FDPSO is made.
Building the building berth of the lower float of the octagonal FDPSO or level land need to meet the octagonal FDPSO's
The size and weight demands of lower float.
The hanging apparatus used need to meet the size and weight demands of mac function.
The hanging apparatus is hung using large-sized gantry or marine crane barge hanging apparatus.
Due to taking above technical scheme, it has the following advantages the present invention：1st, the present invention is since octagonal FDPSO being divided
Construction is carried out at the same time for upper and lower two parts, therefore shortens and takes the time that building berth, dock pacifically build resource, not significantly
Under the premise of increasing construction cost, quick construction purpose is reached.2nd, the present invention by Upper float due to being divided into multiple mac functions
Built, and each mac function is carried out at the top of lower float by modularization assembling by hanging apparatus and is closed up, effectively
Operation side has been subjected to plane expansion, so as to shorten construction period, has reduced construction cost.
