Further, described watertight compartment 20 comprises interior cabin and outer cabin, and described interior freight space is in the periphery of described central chamber, and outer freight space connects interior cabin and works shell in the periphery in interior cabin.Preferably, due to the more close central chamber in interior cabin or moon pool 18, the various petroleum pipelines of convenient connection are therefore described interior cabin is generally oil storage chamber.Air compressor sled piece, public wind tank, instrument wind tank, domestic sewage treatment device, fresh water tank, fire pump room, cabin, heat kerosene storage, diesel fuel tank diesel oil transfer pump, seawater lift pump, seawater filter etc. can be arranged to according to needs as multi-functional cabin in outer cabin.
In addition, the present invention also has the following performance advantage:
Lower apron of the present invention adopts with the lateral layout that necessarily extends out the inclination angle.On the basis with enough oil reserves, good seakeeping performance, to compare with SPAR and dark drinking water semisubmersible, the drinking water of this Novel floating body is relatively shallow, for ease of maintenaince, migration and towage, and can be used for shallow water operations, and the comformability in application marine site is stronger.
The present invention has the waterplane of less, in length and breadth to the equal less of characteristic length, thereby can reduce wave action structurally in length and breadth to hogging or in the flexural load that hangs down.In addition, have the hourglass shape structure of " big in the end and small in the middle " due to invention, buoyancy aid all has higher modulus of midship section in any direction, therefore can further increase structural strength, makes structural bending and fatigue stress be in a lower level.
Lower apron of the present invention adopts with the lateral layout that necessarily extends out the inclination angle.Compare with the cylinder of identical waterplane area and displacement of volume, it is long-pending that this Novel floating body has less fluoran stream surface under water.In addition, extend out the generation that inclined side is conducive to suppress vortex-induced vibration.Therefore, under identical ocean current environment, this Novel floating body can be subject to the current load effect of less.
Symmetric profile centered by buoyancy aid profile of the present invention, can be easily set up central chamber or moon pool in the buoyancy aid center, be used for laying the line, directly lead to all tanks, and no longer need any pipeline in oil, water tank, greatly simplify engineering design, construction and operation, can save the various raws MAT'L such as pipeline and cable.On the other hand, because the similarity degree of each modular construction of Novel floating body is high, be fit to adopt the modularization build process, the difficulty that has therefore reduced design and built.In addition, according to symmetry principle, can with buoyancy aid segmentation symmetrically, reduce main body to the requirement of construction dock, thereby can provide larger selection space to the owner.
The present invention adopts with the lateral layout that necessarily extends out the inclination angle, the volume static moment of water outlet and entry wedge shape in the time of can increasing the buoyancy aid inclination.Therefore satisfy under the condition of initial stability in assurance, along with the increase at angle of inclination, this side view can make the buoyancy aid righting moment increase sharply, and with larger limit restoring moment and angle of vanishing stability.In addition, the inclined side design coordinates the annular side plate structure can greatly increase damping and the added mass that buoyancy aid shakes in length and breadth, thereby can increase natural period, reduces motion amplitude.So when running into stormy waves at sea, the Novel floating body structure namely can not produce violent waving, and can provide enough large angle stability again, has the stability feature of suitable abyssal environment.On the other hand, reduction along with drinking water, waterplane size and the moment of inertia of underwater buoyant body constantly increase, can make up well because displacement and height of center of buoyancy reduce the stability loss that brings, different load-carrying situations are fully loaded so this Novel floating body can promote effectively, the stability of ballast etc., avoid occuring cylinder type FPSO or SPAR platform and hang down and swing the unstable phenomenon that resonance motion brings.
The present invention adopts double bottom, two side structure.This structure can be strengthened the mixing rigidity of main deck and the center shaft of Novel floating body, is conducive to the longitudinal strength of structure.In addition, can be used as ballast chamber in the inner space of double bottom, two topsides, when playing the ballast effect, can prevent that also buoyancy aid from damaged oil spilling phenomenon occuring, and guarantees safety and the feature of environmental protection of production operation.
The present invention adopts the configuration design of single gyro-rotor.Under the prerequisite with good stability and seakeeping performance, overcome the drinking water that causes due to the binary profile load carrying ability has been changed the shortcoming very responsive, that face area is excessive, structure is heavier.Make the main quality of Novel floating body relatively low, improved the capacity weight rate, and reduced the consumption of steel, reduced the cost of structure.
Above water of the present invention adopts with the lateral layout that necessarily extends out the inclination angle.Have under good longitudinal and transverse prerequisite of shaking with the heaving performance, this configuration design with certain flare can reduce the wave climb altitude of Novel floating body, can suitably reduce the shipping of green water phenomenon.In addition, compare with the cylinder of identical waterplane area and volume, the inverted round stage buoyancy aid has less wind area and lower stress action spot.Therefore, under identical sea wind environmental conditions, the suffered wind load of Novel floating body and wind heeling moment are less.
The present invention adopts with the lateral layout that necessarily extends out the inclination angle.Therefore, when sea ice acts on the buoyancy aid side of inclination, will be become by traditional squeeze and destroy the weak bending failure of relative intensity, thereby can greatly reduce to act on the ice load on works, therefore this Novel floating body has comparatively good anti-ice performance, goes for the marine site that freezes.
here, for the good exercise performance advantage of ocean engineering floating working substance of docking circular table of the present invention is described more intuitively, to function (load carrying ability, buoyancy aid volume and upper deck area) identical traditional rectangle barge FPSO, cylindric cylinder type FPSO, round table-like FPSO(is described docking circular table ocean engineering floating working substance with docking) compare analysis, the high frequency motion performance of the various FPSO that the general potential barrier boundary element theory that now will adopt present process to verify calculates is (vertical, rolling and vertical swinging) show as Fig. 4 A and Fig. 4 B, wherein mainly pay close attention to the larger stormy waves frequency band of energy 0.209 ~ 6.28 (1 ~ 30s).
As can be seen from the figure, FPSO compares with the barge type, and when laterally heading sea, vertical the swinging with the rolling motion performance of novel FPSO has larger lifting, and barge type FPSO vertical swings and pitching performance close being more or less the same substantially when vertically heading sea.In addition, longitudinal and transverse the shaking with the heaving performance of novel FPSO all greatly is better than cylindric cylinder FPSO.Therefore, this shows that innovation configuration design of the present invention can increase substantially the hydrodynamic performance of FPSO.
At Fig. 4
A and Fig. 4 BIn, cub represents that (head sea represents the situation of vertically heading sea to rectangle barge FPSO model, beam sea represents the situation of laterally heading sea), cylinder represents cylindric cylinder FPSO model, and sandglass FPSO represents that sandglass FPSO represents docking circular table ocean engineering floating structure of the present invention.In addition, 6 degree of freedom motions are respectively: surging surge, and swaying sway hangs down and swings heave, pitching pitch, rolling sway and head shake yaw.
The above; only be the better specific embodiment of the present invention; but protection scope of the present invention is not limited to this; anyly be familiar with those skilled in the art in the technical scope that the present invention discloses; be equal to replacement or changed according to technical scheme of the present invention and inventive concept thereof, within all should being encompassed in protection scope of the present invention.
