As shown in figure 35, as different from Example 14, semi girder 02, two semi girders 02 that the offshore boring island of the present embodiment comprises described in two embodiments 7 are arranged spaced reciprocally.Without the second through hole 7 on semi girder 02, the hardness offering the semi girder 02 that the second through hole 7 causes is avoided to reduce.Offshore boring island also comprises slide rail 05, and the two ends of slide rail 05 are connected with two semi girders 02 respectively.Derrick 03 is arranged on slide rail 05, and can move along slide rail 05, thus drives the drilling tool on derrick 03 to move along slide rail 05.When derrick 03 moves between two semi girders 02 along slide rail 05, drillng operation can be carried out.
Except said structure, other structures of the offshore boring island of the present embodiment are all identical with the structure of the offshore boring island of embodiment 14.
When ensureing that semi girder 02 does not produce torsion, spacing distance between two semi girders 02 in the present embodiment can up to 20 meters, substantially increase the drillng operation scope that drilling tool can cover, thus greatly improve spudder's bit quantity of offshore boring island, improve the drilling duty of offshore boring island, improve productive profit.
The torsional strength of semi girder is improved by the width increasing semi girder 02 with embodiment 15, thus the coverage expanding drilling tool is further different, the present embodiment is the number by increasing the semi girder 02 on brace table 01, and make the spaced setting of semi girder 02, to expand the drillng operation scope that drilling tool can cover, therefore, when reaching identical torsional strength, the width W of the semi girder 02 of the present embodiment is less than the width of the semi girder 02 of embodiment 15, the weight of the semi girder 02 of the present embodiment is more also compared with the weight saving of the semi girder 02 of embodiment 15, thus the ability that brace table 01 carries miscellaneous part can be improved, as the drilling pipe quantity of carrying on brace table 01 can be improved, thus improve drilling efficiency and the drilling duty of offshore boring island, improve productive profit.In the present invention, perpendicular to the first cylinder axis to direction be rectilinear direction perpendicular to the first cylinder central axis X.
In the present invention, the winding direction of fiber reinforced material line or fiber reinforced material band can regulate according to the Impact direction of semi girder, and preferred winding direction is successively along circumferencial direction and the axially winding of the first cylinder.When fiber reinforced material line or fiber reinforced material band are wound around along the circumferencial direction of the first cylinder, the central axis X of fiber reinforced material line or fiber reinforced material band and the first cylinder is 90 ° or 45 ° of angles.
Embodiment in the present invention, only for the present invention will be described, does not form the restriction to right, other equivalent in fact substituting, all in scope that those skilled in that art can expect.
