Fanyu FPSO i.e. " offshore oil 111 " number is the two ship side structure Floating Production storage in a single end handler, its length overall 262m, molded breadth 46m, designed draft 17.1m, oil storage capacity 157500m
3, life building staffing 100 people.This device adopts the permanent mooring of inner cupola formula, and typhoon is not freed, and can bear storm at sea not seen once in a hundred years.Because of Fanyu sea environment inclement condition, stormy waves is very big, not only device body can produce motion responses such as rolling, pitching and heave, also has distortion vertical in the device body, hogging, device body beam The deformation calculation result: vertical absolute displacement is 327mm, and the maximum vertical relative displacement in adjacent rib position is 25mm; Vertically absolute displacement is 96mm, and the maximum vertically relative displacement in adjacent rib position is 5mm.Device body motion amplitude under harsh environmental conditions is bigger, and its motion amplitude is as shown in table 1 below:
Table 1 is the motion amplitude of No. 111 two ship side structure Floating Production storages in single end of offshore oil handler.
| Motion | In bit manipulation | On the throne extreme |
| Rolling: amplitude cycle | 7.5° | 22.0 |
| 11.0sec. | 11.0sec. | |
| Pitching: amplitude cycle | 4.0° | 8.0° |
| 12.0sec. | 13.0sec. | |
| Heave: amplitude | 0.09g | 0.26g |
According to the motion amplitude shown in the table 1, designed floating type production, storage and offloading device upper module deck support of the present utility model, pedestal configurations is, and main supporting leg 1 is the cylinder of 610mm for diameter, and material is the steel of GB712-2000 D36, and length is 4100mm; Diagonal brace body 2 is the cylinder of 508mm for diameter, and material is the steel of GB712-2000 D36, and length is 360mm, and diagonal brace body 2 is provided with opening 21, and the width of opening 21 is 40mm, and the degree of depth of opening 21 is for being 500mm; Backing plate 4 is the square plate body of 50mm for 1200mm * 1200mm thickness, material is the steel of GB712-2000 D36, three connect plate 3 is that material is the pentagon steel plate of GB712-2000 D36, thickness is 40mm, connect plate 3 and be 1100mm with the length (length of promptly main supporting leg slot) that is connected of main supporting leg 1, the width of slot 11 is 40mm, and diagonal brace body 2 is 500mm with the connection length that is connected plate 3 (being the degree of depth of opening 21).Earlier three length equidistantly being offered in main supporting leg 1 outer rim side is 1100mm, and width is the slot 11 of 40mm, then main supporting leg 1 is vertically welded in the center position of backing plate 4; It is fixing respectively three sides that connect plates 3 to be inserted in the slot 11 welding, and will connect plate 3 bottoms and weld with backing plate 4 and fix; Wherein a connection plate 3 inserts in the opening 21 of diagonal brace bodies 2 settings then, and insertion depth is 500mm, and also welding is fixing, promptly finishes the preparation construction of bearing.
The bearing that the foregoing description is built, directly is welded on the backing plate 4 of fixing main supporting leg 1 on the device body buttress 5 to being positioned on the two middle arranging device body buttresses 5 of device body with the hanging device integral hoisting earlier, constitutes fixed bearing.
Again on the device body buttress 5 that is positioned at the most front-seat and last row of device body, weld 2 baffle plates 6 that are the font of falling L respectively in the left and right sides of device body buttress 5 along the device length direction, the backing plate 4 that to fix main supporting leg 1 then directly is positioned on the device body buttress 5 and makes backing plate 4 be positioned at the limited field of baffle plate 6, constitute sliding bearing, in the wide and short transverse displacement of device, allow backing plate 4 only can carry out appropriate displacement by baffle plate 6 restriction backing plates 4 along the device length direction.
After treating that fixed bearing and sliding bearing structure finishes, module deck is placed on the bearing.
The advantage of the utility model floating type production, storage and offloading device upper module deck support is: 1, at the abominable marine site of sea situation, because stormy waves is very big, cause the device body distortion bigger, therefore be arranged to the part bearing in module deck centre position fixed, and front and back two rows' bearing is arranged to sliding, like this, when distortion appears in device body, because sliding bearing can carry out appropriate displacement along the length direction of device, but even its small amplitude slip on the buttress of device body deck, allow module deck discharge along the length direction of device, thereby reduce the device body distortion, active force to module deck produces reduces the stressed of module deck horizontal direction greatly, and it is reasonable that the module deck structure stress more becomes.2, the module deck support is the bearing that adopts plate body and body to combine, module deck facade framework span is bigger, the usage quantity of bearing obviously reduces, when general every upper module deck uses module deck support of the present utility model, be 3 rows, 4 of every rows are if use the bearing of other types to be at least 3 rows, therefore about 8 of every row can reduce by about 1/2 use amount.3, in bearing, increased the diagonal brace body structure, make between the main deck of device body and the module deck (being that module deck can exceed device body main deck 4.4m) very spacious space can be arranged, device body line pipe carriage can the frame height, operating personnel walk freely betwixt, handled easily, the accumulation of oil gas also can be avoided in open space, improves safety.4, bearing can optionally be arranged on device body stiffening girder position, it is more reasonable to be located at the device body position, can reduce the reinforcement of device body inside in a large number like this, device body design and the workload of building are reduced, save whole engineering time.
The above, it only is preferred embodiment of the present utility model, be not that the utility model is done any pro forma restriction, every foundation technical spirit of the present utility model all still belongs in the scope of technical solutions of the utility model any simple modification, equivalent variations and modification that above embodiment did.
