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, because the more close central chamber in interior cabin or moon pool 18, the various petroleum pipelines of convenient connection are so 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 then as multi-functional cabin in outer cabin.
In addition, the utility model also has the following performance advantage:
Lower apron of the present utility model 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 utlity model 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, because utility model has the hourglass shape structure of " big in the end and small in the middle ", 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 utility model 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 the buoyancy aid profile of the present utility model, can set up central chamber or moon pool in the buoyancy aid center easily, be used for laying the line, directly lead to all tanks, and in oil, water tank, no longer need any pipeline, 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 symmetrically segmentation of buoyancy aid, reduce main body to the requirement of construction dock, thereby can provide larger selection space to the owner.
The utility model 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 guaranteeing, along with the increase at angle of inclination, this side view can so that the buoyancy aid righting moment increase sharply, and with larger limit restoring moment and angle of vanishing stability.In addition, the inclined side design cooperates 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 remedy 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 utility model 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 utility model adopts the configuration design of single gyro-rotor.Under the prerequisite with good stability and seakeeping performance, overcome because the drinking water that the binary profile causes changes the shortcoming very responsive, that face area is excessive, structure is heavier to load carrying ability.So that the main quality of Novel floating body is relatively low, improve the capacity weight rate, and reduced the consumption of steel, reduced the cost of structure.
Above water of the present utility model adopts with the lateral layout that necessarily extends out the inclination angle.Have under the 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 eight terrace with edge buoyancy aids that fall have 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 utility model 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 the 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 eight shuttle table types described in the utility model 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, eight prism-frustum-shaped FPSO(are described docking eight shuttle table type ocean engineering floating working substances 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 such 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 vertical the swinging with the rolling motion performance of novel FPSO has larger lifting when laterally heading sea, and barge type FPSO vertical swings and basic close being more or less the same of pitching performance 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 utility model can increase substantially the hydrodynamic performance of FPSO.
