The invention provides an operation method for installing an upper module structural sheet. The operation method comprises the following steps that S1, a self-propelled module transport vehicle is adopted to transport the structural sheet to the position below a gantry crane in a land construction closure site; s2, the gantry crane lifts the structural sheet; s3, the self-propelled module transport vehicle advances to a specific position below the supporting tool, the top height of the self-propelled module transport vehicle is adjusted, and the supporting tool is borne by the self-propelled module transport vehicle; s4, the gantry crane downwards places the structural sheet on the supporting tool; and S5, the self-propelled module transport vehicle transports the structural sheet to a preset position in the upper module, and installation of the structural sheet is completed. The method has the beneficial effects that the self-propelled module transport vehicle and the supporting tool are matched to hoist the structural sheet to the height required by post-installation, the post-installation problem existing in the land construction closure stage of the upper module structural sheet is effectively solved, and the overall operation steps are simple, safe and reliable.
Description
technical field [0001] The invention relates to the technical field of offshore oil platforms, in particular to an operation method for installing upper block structural sheets. Background technique [0002] In recent years, due to increased efforts in the exploration and development of offshore oil and gas resources, the jacket platform as an important facility for the development of offshore oil and gas resources has been widely used. The existing jacket platform includes a jacket and an upper block arranged on the upper part of the jacket. The upper block involves multiple specialties and is difficult to construct. Currently, the construction process is mainly divided into pieces, that is, considering factors such as site resource allocation and structural layout, etc. The upper block is divided into multiple structural pieces, and each structural piece is transported to the land construction and closing site for final assembly and closing after prefabrication in the work...
