Embodiment Construction

[0022] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0023] Taking the post-docking process of the jack-up platform spud shoe on a 90-meter offshore platform as an example, the following steps are included:

[0024] A. Tooling production and installation in place: First, it is necessary to determine the end position of the spud shoe in the dock and the entry path of the spud shoe. At the same time, the entry method needs to be considered. This plan considers the use of three rails 1 plus specific tooling 4. By considering Special tooling 2, firstly install the track, and then make the special tooling. When laying the track, the butt joint area should be considered. There are no joints and track fixing devices in the projected shadow area under the main hull of the spud shoe, so that the track can be placed after the spud shoe is in place. dismantled in time;

[0025] B. Complete loading of the main hull:...

Abstract

The invention discloses a subsequent docking process of self-elevating platform pile shoe. The process comprises the steps of tool production and accurate installation and complete building of a main ship body. In the step of tool production and accurate installation, firstly, a final position of a pile shoe at a dock and a docking path of the pile shoe are determined, and a docking mode is considered; the process uses the combination of three rails and a special tool; for a special tool 2, the rails are first mounted; then, the special tool is produced; a butt joint area is considered in the laying of the rails; joints and fixing devices of the rails are absent in a projection area of the lower position of the main ship body of the pile shoe so that the rails can be timely detached after the pile shoe is mounted in place. In the step of complete building of the main ship body, the building of the platform main ship body is performed according to a design drawing without considering the pile shoe and pile legs. The building method of the process has the advantages of high building stability, prevention of mounting accidents such as collapse, high building speed and high quality, and is well received by customers.

Description

technical field [0001] The invention relates to a post-docking process for spud shoes of a self-elevating platform, and belongs to the technical field of ships. Background technique [0002] With the development of modern science and technology, the shipbuilding industry is developing more and more high-end, from the original small wooden boats to 10,000-ton steel ships, especially the construction of large offshore platforms, which has pushed the marine industry to the highest end, but The construction of the offshore platform is very difficult. Because it has four legs, it bears a lot of weight in the dry dock, and it is easy to collapse if it is directly supported by the legs. It must be built with appropriate technology, which is an urgent problem to be solved. Contents of the invention [0003] The purpose of the present invention is to provide the subsequent docking process of the jack-up platform spud can. [0004] The problem to be solved by the present invention ...
