Abstract
The utility model discloses a marine drilling platform enhancement pile leg, comprising a pile shoe, a main steel pipe, a horizontal support pipe and a pair of oblique support pipes. The main steel pipe, the horizontal support pipe and the oblique support pipes are arranged on the pile shoe to construct the pile leg. The oblique support pipes are symmetrically and obliquely welded on the horizontal support pipe. The welding positions of the two oblique support pipes are in lapping joint with each other. The welding gap between the oblique support pipes is roughly in parallel with the radial section of the horizontal support pipe. Thanks to the lapping joint of the welding positions of the symmetrical oblique support pipes and that the welding gap between the oblique support pipes is roughly in parallel with the radial section of the horizontal support pipe, the entire support power of the pile leg is improved. The influence caused by wind, wave and seawater flow is reduced, compared with an X-shaped pile leg steel tube structure.
Description
Technical field
The utility model relates to a kind of reinforcement spud leg that is used for the seawater offshore boring island.
Background technology
As shown in Figure 5, the string tubular structure of offshore platform drilling well spud leg adopts lattice section point form mostly at present, and down tube 2,3 symmetries tilt to be welded on the horizontal stay tube 1, have certain distance between the down tube 2,3.Continuous expansion along with the offshore boring island scale, spud leg is also had higher requirement, not only need spud leg that higher bearing strength is arranged, but also want to resist Effect of Environmental such as wind, wave, stream better, deposit ability certainly with lifting platform adaptation severe sea condition work capacity and storm.
The utility model content
Technical problem to be solved in the utility model is to provide a kind of offshore drilling platform to strengthen spud leg, higher enabling capabilities is not only arranged, but also can reduce the influence of environment such as wind, wave, stream.
A kind of offshore drilling platform of the present utility model is strengthened spud leg, comprise: shoe, main chord tube, horizontal stay tube and down tube, main chord tube, horizontal stay tube and down tube are built and constitute platform leg in shoes, the down tube symmetry tilts to be welded on the horizontal stay tube, this a pair of down tube overlaps mutually at weld, the radial section almost parallel of weld seam between the down tube and described horizontal stay tube.
The utility model is by overlapping symmetrically arranged down tube mutually at weld, and make the weld seam between the down tube and the radial section almost parallel of described horizontal stay tube, thereby improved the integrated support ability of spud leg, and compare with X type leg-chord tubular structure form, also reduced of the influence of environment such as wind, wave, stream spud leg.

Fig. 2 be among Fig. 1 D to enlarged diagram.
Fig. 3 be among Fig. 1 E to enlarged diagram.
Fig. 4 be among Fig. 1 F to enlarged diagram.
Fig. 5 is the prior art structural representation.
The specific embodiment
As shown in Figure 1, 2, the utility model comprises: shoe 11, main chord tube 14, horizontal stay tube 15 and down tube 12,13, main chord tube 14, horizontal stay tube 15 and down tube 12,13 are built in shoe 11 and are constituted platform leg, down tube 12,13 symmetries tilt to be welded on the horizontal stay tube 15, this a pair of down tube 12,13 overlaps the weld seam 16 between the down tube 12,13 and the radial section almost parallel of horizontal stay tube 15 mutually at weld.The material of main chord tube 14, horizontal stay tube 15 and down tube 12,13 can select yield strength to be registered as the high strength steel of 690Mpa and 520Mpa.The design can be more firm than traditional X type welded construction, not only improved the enabling capabilities of drilling platform leg, and can reduce environmental impact factors such as 7% wind, wave, stream.
In addition, if be positioned at the position at spud leg middle part, then as shown in Figure 3, down tube 12,13 not only is symmetrical set, and symmetrical up and down; If be positioned at upper position, then as shown in Figure 4, down tube 12,13 is symmetrical set in horizontal stay tube 15 bottoms.No matter adopt which kind of mode, the weld seam between the down tube 12,13 all with the radial section almost parallel of horizontal stay tube 15.
Claims (1)
