Abstract

The invention discloses a method for welding a pile leg and a pile shoe of a drill platform. The pile shoe comprises a pile shoe main body and an upright plate component. The method comprises the following steps of: a) welding the upright plate component on the pile leg; b) inserting the upright plate component connected with the pile leg into the pile shoe main body, and c) welding the upright plate component inside the pile shoe main body. The method of the invention solves the problem that the exterior of the pile shoe is difficult to weld because the working station space is narrow. The welding quality is ensured, the welding cost is saved and the construction period is shortened.

Description

technical field [0001] The invention relates to ocean drilling equipment, in particular to a welding method for pile legs and spud cans of a drilling platform. Background technique [0002] For some offshore oil drilling platforms, such as the CJ series platforms designed by Gusto MSC in the Netherlands, the roots of the pile legs are welded on the outside of the spud cans, and the 18 welds will fully bear the lifting weight of the platform (the maximum weight is about 20,950 tons). The importance can be imagined. According to this type of platform structure, the welding seam between the pile leg and the spud can is special, and the space of the welding station is particularly narrow, such as figure 1 As shown, the gap between the spud leg 2, the glideway 3 and the spud shoe 1 is about 135 mm, which is very narrow, so engineers cannot weld from the outside of the spud leg and the spud shoe at all. At present, for the CJ series platforms of Gusto MSC, the major shipyards ha...
